Maybe you need to cool the generator when it stops working the fan like in tropical/subtropical climates? That's my best explanation,but I'm not very smart about generators...
When I was in the military while in the field we used generators. To quiet them, you dig a small hole and surround it with filled sand bags, little higher than the generator . Totally absorbed the sound!
Exactly. It comes down to basic principles of sound transmission. Dense materials like sand / pile of rocks will do far, far more than some kind of BS frame or enclosure.
Yep, always dug in the gennys if possible. It also helped with identifying direction, that said, the old thumper generators were like a noise beacon in the night, nothing tactical there.
The generator that I've been looking at getting is $1,700, uses propane or gas. The reason I'd want it, is because I'd often be using it inside of buildings that don't have easy access to a 220v outlet. -- So, while I can understand this isn't exactly a common practice use, there are people that would greatly appreciate the machine.
Honda inverters generators are insanely priced too (repeatedly mentioned in the video). If I could parallel 4 of them, I'd finally have a decent sized generator but I'd need a bottomless wallet to due it. It's not hard to be quiet when you're running a Cox 0.049 engine (exaggeration) and take your fuel consumption ratings using 1/4 output (when output is already 1/2 regular generators. Other manufacturers rate sound output and fuel consumption @ 1/2 output, not 1/4. Let's try some apple to apple comparisons. The inverter don't enter into the reason they're quiet it's because they are 1/2 the size both in output power and engine size (or more) along with twice the price tag.

No offense, but I guess you are a master of none and a novice of many. -Boxing in the generator will make the motor run hotter than normal. It actually should stop running if u box it as it likely has a CO kill on the generator. -you especially hold the wood(in this case with a push stick-or you should) that is between the table saw blade and the fence. You are just asking the wood to pinch and potentially snap the blade sending metal at you. -you know, you could skip getting a battery fan and plug in a fan to an outlet on the generator... -plug the hole with "a thick piece of rubber" when you show a picture of patching a drywall hole with mud over mesh. among others.
I always advise against #4 - car muffler. It doesn't make a significant difference AND more importantly it'll increase the back pressure on the engine causing premature failure.
Even a muffler for a 1.3l engine is not going to create any real back pressure in these tiny generator engines. It will not shorten the engines life. Best practice is to use a motorcycle/scooter muffler, with the scooter muffler designed for smaller engines similar in displacement to a generators engine.
@@KhlandestineThe short answer is yes, but it depends on the size of the engine of your generator. You should do your best to match a properly sized muffler to the displacement of the engine. You should be able to find generic guides online.
I mounted a 250 amp dc alternator on the engine of one of my little Honda cars. Then I wired it to a 120/ 240 volt ac inverter . I have a breaker power box that allows me to plug the 10,000 watts inverter to my house through a throwover switch. With an adjustable throttle cable, I can park the car outside my garage and plug my house into the cars power inverter and power most of the house with a cord we got from a trailer house we got rid of some years ago. Our propane house heater is no problem, but can only run one ac unit on the house. But everything else works fine. And you can't hear the car running at all. And since it's water cooled it never overheats. It's the car we take camping, so we always have all the electricity we want. Thought about building a generator head attached to a car motor on a trailer, but this works good as is. And easily portable. You can barely hear the car running.... And the best part I'd it sips gas and I can drive to to the gas station for more gas.
Umm I don't think you need a battery powered fan if you are running a generator. Just plug it into the generator (roughly a 100 watts depending on the size of the fan)
Zombie box uses a solar powered fan with a storage battery for night time use. the solar fan can be bought at hardware store if you want to make your own
Thank you for sharing this nice video. I apologize if someone else already mentioned what I am about to say because there are currently 397 comments to dig through. People need to be careful modifying the exhaust systems on an engine. All engines have an ideal amount of back pressure required to achieve the most power at the least amount of heat out of the engine while compromising a bit of power loss for noise reduction. There is usually a sweet spot that the engineers already hit for you. Maximize power, reduce heat and decrease noise. When you add another muffler you could be significantly increasing the backpressure on the exhaust port of the cylinder(s). This will reduce power and can also affect carburetor jetting efficiency. The noise mat and sound suppression box are a great approach so long as the engine has proper ventilation. If you stick it in a box, the oxygen level in that box will drop and that will cause the engine to run richer in fuel. So assuring the air intake at the air filter is closest to or outside of the box would be best. All of the better engine companies do extensive testing to maximize the output of their engines. When they run their tests they do so in varying environments such as high altitude, cold climate, hot climates. However they do not assume someone is going to put the engine inside of a box and this could have a detrimental impact on the engines lifespan / fuel consumption and performance. Ok, preaching over with now.
The ideal amount of back pressure is always zero. Any amount of back pressure will reduce power since it requires the engine to do more work to expel the exhaust gasses. Exhaust tuning revolves around pressure waves and their termination. By altering when the pressure wave is terminated, you change what RPM peak torque and power occurs at by making use of the scavenging effect to increase cylinder filling at specific RPMs. That is what hot rodders do with headers and muffler placement. Car mufflers will flow more than enough for any small engine to not add back pressure, however it can change when the pressure wave is terminated and that can change when peak power occurs. Since most small engines operate in a small range of RPMs, 3,600 or less, a shift to a higher rpm would be noticed as a loss of power in the lower operating range because the engine will never turn enough RPMs to achieve the new peak scavenging.
Unlike a box, the plywood is angled so that the noise is directed downward. A box is not angled, it's just 4 vertical walls which keep the sound inside without any directional focus. So a hole would disrupt the acoustics from being enclosed inside.
He said leaning boards will reduce the noise by 10 decibels. A hole in the box will let the sound waves out. You are trying to compare apples and oranges.
@@user-1A-2A These are two different sound dampenings going on here. Angling the boards against the generator deflects the sound downwards and into the sound absorbing grassy ground. If it were concrete it would not work as well. The other was a cabinet where it is designed to hold the sound waves inside the box and just like a damper in a speaker box if there is a hole in it, the sound waves will escape.
Some of these ideas will definitely make the generator quiet but will also cause it to run hot with improper ventilation which will shorten the life of the generator
Moving the generator away from the house requires wire gauge considerations and becomes important ... the longer the wire ...greater the load loss. Can become very expensive.
I tried an extra muffler i had lying around first, on my Chinese 5kw diesel, but made very little difference to noise outside(generator was in garage with exhaust going thru wall outside). So found a 2 meter long piece of old lead bath drain pipe i had lying around, and attached that instead, worked well, without a meter to test though, but seemed like about 50% reduction.
I used to have one of those 2-stroke, 800 watt Harbor Freight generators. Chincy little thing, but it worked quite well for running some lights and fans during camping on hot summer nights. I put the 'genny about 100 feet away, over a hill. Then a 10 foot long bit of electrical conduit large enough to slip over the little exhaust outlet with the spark-screen in it. A small hook clamped about 5 feet down the pipe where a bungee with a metal hook was connected, then the other end connected to the frame of the 'genny to keep the pipe tight against the exhaust. Finally, a Y-shaped branch jammed firmly into the ground to support the far end of the pipe. By the time the exhaust had exited the pipe, it was barely warm. All that, and a few bits of wood stacked as mentioned. This was in a state park campsite. During the still hours of the night I could just barely hear the 'genny. I asked neighboring campers if they heard anything, and if so, if it was bothersome. Nobody, not even the park rangers could tell that it was a generator only 100 feet away. It sounded pretty much like a window air conditioner running across the street. With little load, one full tank lasted all night, and long enough into the morning to make coffee. I sold it to my brother 10 years ago. He still uses it on jobs. Now I have an inverter 'genny. I still use the stacked wood method, but with 2 inch thick, rubberized-coated Styrofoam insulation boards rather than plywood. (Leaving openings for air and fully open on the exhaust end) Cant hear the thing at all. ALWAYS.. ALWAYS! Secure your 'genny with a lock and chain around a tree at least 6 inches thick. Junkies & crackheads are everywhere trying to steal anything to sell for their next hit. CHAIN IT UP!
I know this ia an old comment but i am interested in exactly what materials u used to make your "rubberized coated insulation boards". Were they actual wooden boards lined with styrofoam? Or were they styrofoam only? If styrofoam only what doyou use to keep them from blowing away? What kind of styrofoam? What was the rubberized coating? Rubberized Undercoating? A thin rubber mat? Thanks in advance.
@@webstella What I had was some kind of underlayment my uncle got from a jobsite he worked at. An insulating foam that goes under the steel sheeting. Basically, it was a panel of 2 inch thick, white strofoam with this black cating on it that was elastic and rubbery. But it looked like black cork. I have never seen anymore of that stuff since. But I never really looked for it either. Ok I just googled several keywords, and nothing similar comes up. I was trying to give you a link to a photo or source, but I'm having no luck. The closest thing I could find was Polystyrene "Sandwich" board. But it has metal cladding rather than the rubberized coating. As for the method I used to keep it in place, I used landscaping fabric pins. I just pinned then together in a 3-sided box shape and put it over the "genny, with the exhaust pointing out of the open end. Sorry I couldn't give you more info. I really do wish I knew what the stuff was called.
Best way to eliminate generator noise is to put it far enough away from your home so that someone can easily steal it. Once it has been stolen, things will be nice and quiet.
The instructions for the generator I have says to leave at least four feet of free air around the unit to prevent overheating. How is enclosing it in a wooden box not going to cause it to overheat and possibly ruin the generator ?
@Michael Miner Isn’t a plywood box a solid barrier? Plywood seem pretty solid to me. I guess that I’ll have to make a 10’x10’ shed with insulated marine plywood walls to give it plenty of breathing room. Another project.
Hey man! You'll have to install some fans/vents. I'm still in the process of designing my compartment for my generator, so I can't help you with specifics, but a dude on a forum told me he built his with vents that had small fans built in, and he somehow wired the fans in with the generator so anytime it was running the fans were running as well
@@jamesgaudreau8315 Sounds cool, no pun intended. I’ll look into the fans, maybe on on each end. Do you think that both should exhaust the air, or maybe one to exhaust and one to bring in cooler air from outside. Just a thought.
@@rayhs1 or where I live there are boulders under the surface here bigger than a vw bug. They are building a new house across the street and you should have seen these huge boulders just under the surface.
I did that too but I left it in there too long and when it rained, it got flooded in my hole! Also when I covered my hole, it choked my generator out. I'm going for the vented box now
quick safety tip. I work on powerlines and during storm restoration we love to be able to hear a generator running. If a generator is incorrectly installed it can backfeed the high voltage and kill us. When we hear it, we know to be more wary. Great vid! TLDR: keep it loud after a storm.
My first time using a generator after a winter storm resulted in having the cops come to my house on a noise complaint and me getting a written warning that the generator would be confiscated and I would be fined if they got another complaint.
Perhaps buy a better generator to start with! A better, more commercial generator typically rotates at 1800 RPM instead of the typical home generator bought at a big box store. The typical lower cost generator turns at 3600 RPM.... do you see a problem here? You can put all the mufflers you can afford and it won't help a noisy motor clanging away at 3600 RPM. Buy a better designed commercial or long life generator turning at 1800 RPM. It will be significantly quieter and lasting much, much longer.
Never point a generator exhaust toward your home or place your generator in a garage or carport area!!.., whether you are looking for a quieter sound or not...you would be pointing carbon monoxide laden fumes toward your living enclosure
Everyone talks about inverter generators on how good they are, and how quiet they are. Well, let’s see how long they last and when they do break how much they are to fix. There is a lot more to an inverter generator than just a motor and an alternator. A lot of technology, and you know that technology is exposed to heat, cold, and humidity
Be careful about useing wood, wood absorbs gas fumes making it flammable, its what happened to my neighbor, the fire spread to his house and burnt the house down.
Oh, man I wonder how long before the box would catch fire with my 8500 watt genny. We had a power outage a few weeks ago and can run the entire house on it, plus one AC. The muffler glows red, you can see it at night. If you stand 5 feet from the exhaust, your legs get hot. This is at 50% load too! Imagine if we cranked up two AC! One thing I can say, enclosures do work, provided they are designed with cooling and exhaust ventilation in mind. For example, look at the Generac 7.5Kw genset. Its basically the same as a caged generator, but in an enclosure. The key though is that it has plenty of ventilation and the exhaust is piped out of the box so it doesn't release its heat inside it. I also know that the alternator in the genny has a good sized fan to suck heat out, so making sure there is good in flow and out flow is key. If you do make an enclosure, make sure the front and back, in relation to the genny, the front would be the motor side, the back the exit of the alternator where the air blows out, and some method of getting the exhaust out, and it will work. Give at least 12" clearance all around. Here is the MOST important ting, Make sure you can open it up to air out BEFORE starting it! Gas fumes can and will accumulate in the box and if you have a power starter, and you push the button, you could very well go BOOM!
You have zero actual experience dealing with this problem. Half your stuff contradicts itself. Several of your video clips swiped from other youtubers. Several tips are dangerous.
He's trying to cure diarrhea by fixing the toilet. Buy a twin cylinder inverter Cummins/Onan genset or Honda and Yamaha and Suzuki make them too(yes, they are expensive, but you can hand them down to your grand kids if you maintain them) and be done with it. What is the ONLY brand of generator that can be used in ALL National Park Campgrounds after "Quiet Hours" and all National Forests and all State Parks and all Corps of Engineers Recreation Areas? Onans. I had an Onan 11000 Emerald Series in an AirStream Excella MotorCoach and put 55000 hours on it with only oil changes and new spark plugs. When the vehicle ran, so did the Onan for the twin roof Coleman A/C's. We got better fuel economy that way, 15.5 MPG VS. 14.5 trying to use the the cab A/C to cool the rig (pulling different Hondas, Civic or Accord Hatchbacks didn't make any difference). 454CID Chebby slightly worked on(headers and Jacobs ignition replacing the worthless GM HEI), G50 chassis, 400 Turbo-HydroMatic 19" Alcoa wheels. I THINK Yanmar makes a liquid cooled des-iel inverter genset that's quiet as a baby's breath too. Look at what's at the base of the local cell phone tower for a back-up. Ex-room-mate installs and maintains those things...
confused. dont leave any tiny gaps but you need holes of sort for ventilation and exhaust. oh and best yet dont point the exhaust towards your house. do it like my neighbor and point towards my house.
Two things you didn't mention is you can bury the generator and you can run the exhaust into a bucket of water as long as you leave a small hole for backdraft..I have used boards to silence one and it worked really well...also one thing you said that made me laugh was you could get a battery operated fan to use in the shed....not like there is a huge generator or anything in there to hook up a box fan 😊
2:27 the guy running the table saw doesn't know what he's doing to the point of endangering himself and people behind and around him. After running a table saw for a minimum amount of time, it becomes evident as to why. This tells me that this guy has almost zero experience with a table saw. I'm not even going to waste my time explaining it. Other than that, this video was beneficial to me. Cheers
I have a predator just like this. Muffling the exhaust is of zero effect. The noises overwhelmingly from the motor crankcases. The enclosure has merit. Exhaust muffling is simply ignorant crap.
Exactly. Exhaust noise is a small percent of the noise. I dug a 5x5x5 hole in the ground , covered it with a roof and big exhaust fan, and I can barely hear my genset now.
@@FrustratedBaboon I've recently had a Full House generator installed, and I'm looking into ways to mitigate the noise, I'm looking into something I can build myself.
@@sambiscits6711 I'll build my own as well. Gonna spend extra for 500+ CFM exhaust fan and air filter so that the internal temp is only a few degrees higher than outside.
Don't run your extension cords any longer than necessary and if you do need to, make sure you match your gauge size to the distance and load to be used. Running too small of an extension cord a long ways could overheat, causing damage or even a fire.
It also makes the devices consume more amps... You're actually consuming more power from your generator cuz part of it is heat. I found out a long time ago my generator couldn't start a circular saw with too long of an extension cord..... But with a short extension cord.. no problem
We stuck ours in our old abandoned mini van, we just drilled a small hole in the gas tank to get rid of the gas. Keeps rain off it. Works good! Can barely hear it.
You need a thicker cord. If you are going 100 feet, get a 12 gauge cord. More expensive, but it won't heat up and it won't offer as much electrical resistance. It's not just a matter of how much it taxes the generator, but also how much power loss you have at the far end.
You use the proper size cord for the amperage you're feeding and for ever 50' extra length the cord is, you size up (bigger) one guage. For instance, if you're running a standard 15A circuit at 110-125v up to 50 ft you would use a cord that is 14 guage and if it's between 50' and 100' you would size up to 12ga etc. 16 guage is good for 10A at up to 50 ft.
I rigged my Duramax dual fuel generator with the gen turi exhaust system,which takes exhaust noise up 16 feet thru pipes,and it also takes heat with it,so noise,heat and fumes are up above our campers and others,also have a box that Al this goes into,so on full load noise is around 42 decibels.
DO NOT RUN YOUR GENERATOR IN A SHED.Manufacturers of generators strongly warn against running a generator in a shed or garage under any circumstances, even with the door wide open. Carbon monoxide is very dangerous! You can't see or smell it. Eventually you will need to go into the shed to add gas to your generator, and it will be full of CO. Whoever made this video does not even mention using a carbon monoxide detector. DO NOT RUN YOUR GENERATOR IN A SHED.
Car muffler will not work because it need large amount of air to cancel its own sound. Don't spend $200 on "gen-silencer". You can get same result from $15-$30 exhaust from Amazon just type "generator exhaust". Don't forget to use 90* elbow when connect to new silencer.
Big mufflers never work. It’s the fact that a small 4 cycle engine has to rev to 3,600 RPM it’s the engine itself and the surrounding parts. VIBRATION IS THE REASON FOR THE NOISE, ALSO, SIZE MAKES NO DIFFERENCE I OWN A GENERAC GP 17,500E ITS A 992CC V TWIN AND WEIGHS 400-500LBS ITS LOUDER THAN ALL OF THEM!! LOTS OF MISS INFORMATION AND HAPF FACTS HERE.
Assuming I face generator away, no echo, fumes or heat issue, CAN ANYONE PLEASE “ONLY” JUST TELL ME 1-WHICH OF THESE 11:00 FOLLOWING METHODS IS QUIETEST>>1-HOMEMADE A FRAME BOX(construction material, 2- MUFFLER(type) or 3-OTHER? Thanks in advanced!
or - she could just up and leave you - am sure there are plenty of guys more than happy to listen to her. You don't sound as though you'd be great conversation yourselves :-(
sound proofing a generator like this can cause damage to the Generator . 1 it can cause the generator to over heat .has to be vent very well then you lose the sound proofing . also alot of gens have alot of plastic's on them that can warp over time use due to the heat . intakes . carbs can be plastic . elec control are plastic that do not do good in the heat . most Gas gen are loud . propane gen run alittle smother and alittle more quieter then gas . but if you do this you do it with a bad risk . risk over heat wharp plastic due to over heat elec failure due to over heation elec control system has silcone base to weather proof elec that can melt an turn it into a 700$ repair . an sometimes parts you can't get specailty with honda generator's since Honda loves to not make part for engine's or generator parts for to long . 10 years i think is the max . also you can blow your self up . due to the gas tank being mount on the generator . SO DO AT YOUR ON RISK! IF SAY IT CAN BE PUT INTO A BOX PUT IT IN A BOX OTHER WORD'S THEY MAKE QUIETER GENERATORS
The best way is not to buy these cheap units they all run at 3600 RPM buy a Onan they run at half that RPM I own a 28 KW unit that is powered by. 4-53 Detroit 2 stroke Diesel engine I bought it for less than some of the gas units it’s 3 phase I bought a transformer to convert it’s out put to 240 volts 1 phase along with a big transfer switch that runs the whole farm for $300 I used a semi muffler on it it is in its own insulated metal building you can hardly hear it I have a used semi 100 gallon fuel tank that feeds it along with 1500 gallons in the ground tank for the the equipment. Shop around you can find bargains and do not forget army surplus you find any thing look up government planet.
Just to correct the information, no small engine is splash oiled anymore. Flathead engines will not meet EPA requirements and OHV requires an oil pump. The easiest way to deal with a generator is to make a corral of filled concrete blocks in which to run it. It only has to be as tall as the generator.
Just buy a variable speed, quiet, inverter. Don't do this dumb shit! "Lets cover gen set with plywood". So it will over heat? Big muffler is waste of time! Buy a 500' extension cord?
The muffler one is a joke and dose not work, I seen a video of a guy who repairs generators and he used a sound decibel meter and that there was no difference in sound with a car muffler and without a car muffler added to it. So DON'T WASTE YOUR TIME WITH IT.
How exactly are you supposed to be able to return a muffler after you've welded it to something as you suggested ??? Also a zombi box for 1K !!! ... Now I see why you never purchased one like you said you were going to in your last video about generator noise. Out of curiosity you had to know what the price was so why didn't you want to share it with us ? Because you know that it would be a complete waste of money and one can make one themselves for a third the price. This is the soundproof guide channel 😆🤣
2 in Styrofoam 3 sided box and lid. Leave the exhaust end open facing away from your home . Use velcro and bungee cords to assemble. Easy to take down for storage .
A Zombie Box or an enclosed soundproof box sounds like a good idea, but what about all of the heat? Where does it go? Out that small ventilation hole. It might work for 20 minutes. But after an hour or so, it's going to shut down and most likely destroy the equipment. Generators are air cooled. If there's no air getting into the enclosure, how does it get cooled? If you figure out the cooling issue, please let me know. I would keep one side open and aim a large fan at the generator. Unless you don't like your generator, then do whatever.
Compresión sounding like air-conditioning like police and security cars have except getting stuck or chasing somebody the compressed thing off by its self and loudness comes out automatically or if it has bad muffler senior trucks nowadays and delivery trucks and cb performance and stock engine ones and school buses delivery trucks same thing but made of stroker but bigger boxer Volkswagen custumized deisel turbo and desil stock engine or all four in some they compress the noise sounding like normal truck and Volkswagen cars Volkswagen street Volkswagen and trucks like normal sounding but air-condition sounding tinging
Obviously - buy a quiet model first, but after that use the landscape to your advantage - put in a dry ditch or behind rocks, or dig a pit and use the spoil to fill sandbags or fabric bags and place around it like sand bags. Stagger an entrance for access and exhaust as sound does not travel around corners well. Then use an old soggy plywood roof, or use earth on top. Parking it on planks or a board supported at the ends like a bridge will prevent the ground vibration problem.
So the blap blap blap noise is from the crankshaft , not the explosion in the cylinder. ? I have a car muffler and all you can hear is the intake noise so . Oh my god now your saying ... oh i quit ...nvmd
Yes, you can have a problem, the engine could overheat. The engine operating temp could be as high as 200* f in that box with no problems. However, the generator wiring insulation maybe only rated at 105*c or 220*f
Any box should have fresh air only duct, vent, opening to cool the engine and gen head made in such a way that the intake air does not mix with the heated air under the box. The box will pressurize and will need a vent back out. An exhaust fan will not be sufficient to keep heated air from recirculating though the engine and run too hot. The engine carb intake should have new air also. This is how Enclosed generators work. The front of the engine and the back of the gen head is where air is pulled in.
Bravo.........the box needs 150cfm air blower......for cooling...........best .....pipe the exhaust into 5 gallon metal bucket filled with water......like a boat......cheers
Lol, I hope zombie fires their engineer. Radiant barrier around a heat source when cooling is benifical ? Ha ha ha. Unless it's used in the south pole why?
Your gonna be have to disable the carbon monoxide unit if you have the a generator with this. I was just putting Oly wood around mine and it shut off. So I just disabled the carbon monoxide unit.
Any holes you make in your shed are going to allow sound to escape. The holes need to be covered with a baffle to break the sound up before it reaches open air. This includes air intake and heat exhaust fans. Isn't a gen 'silencer' just another name for a 'muffler'? When building a sound-proof enclosure, you should think in terms of reflective, absorptive, and inert layers. Innermost is reflective, next is absorptive, with the outermost inert. The inert layer prevents the engine's noise from being transmitted into the surrounding environment. See the comments about sandbags below.
@@westmcgee9320 right right. Like dont build on out of paper or cloth and several other obvious materials that wouldn't help. Like toilet paper, or silk.. but basically any kind of wood enclosure. The thicker the better.
When your power is out why would you care how loud the genny is? You got power. That's all that matters. Neighbors can hear it and sit in the dark with jealousy.
Mostly not at all useful information. And sometimes silly. And put a long extension cord on it? Any idea what gauge wire you would need for 5 or 6 Kwatts to extend it 100 or 200 ft? VERY BIG!

-plug the hole with "a thick piece of rubber" when you show a picture of patching a drywall hole with mud over mesh.
among others.
I don't even have a generator and I'm watching this because I'm bored while quarantined...
Awesome! Keep watching and subscribe to my channel and most of all, stay safe ☺️
So cool😂
That's funny, nearly the same situation
lmao
😂🤣😂
I always advise against #4 - car muffler. It doesn't make a significant difference AND more importantly it'll increase the back pressure on the engine causing premature failure.
I agree with you
Even a muffler for a 1.3l engine is not going to create any real back pressure in these tiny generator engines. It will not shorten the engines life. Best practice is to use a motorcycle/scooter muffler, with the scooter muffler designed for smaller engines similar in displacement to a generators engine.
@@JV-io3nndoes it actually help at all? The scooter muffler?
@@KhlandestineThe short answer is yes, but it depends on the size of the engine of your generator. You should do your best to match a properly sized muffler to the displacement of the engine. You should be able to find generic guides online.
Yes, point the exhaust toward your neighbor's house!
Loll I'm doing that now😅😅😅🤣🤣
that'll teach them!!!
I mounted a 250 amp dc alternator on the engine of one of my little Honda cars. Then I wired it to a 120/ 240 volt ac inverter . I have a breaker power box that allows me to plug the 10,000 watts inverter to my house through a throwover switch. With an adjustable throttle cable, I can park the car outside my garage and plug my house into the cars power inverter and power most of the house with a cord we got from a trailer house we got rid of some years ago. Our propane house heater is no problem, but can only run one ac unit on the house. But everything else works fine. And you can't hear the car running at all. And since it's water cooled it never overheats. It's the car we take camping, so we always have all the electricity we want.
Thought about building a generator head attached to a car motor on a trailer, but this works good as is. And easily portable. You can barely hear the car running.... And the best part I'd it sips gas and I can drive to to the gas station for more gas.
Umm I don't think you need a battery powered fan if you are running a generator. Just plug it into the generator (roughly a 100 watts depending on the size of the fan)
You could certainly do that if you don’t need all of the outlets.
@@soundproofguide That's what Zombiebox does with their fan.
Just use an outlet expander of some sort or take remaining power from a multi-outlet cord.
Zombie box uses a solar powered fan with a storage battery for night time use. the solar fan can be bought at hardware store if you want to make your own
Thank you for sharing this nice video. I apologize if someone else already mentioned what I am about to say because there are currently 397 comments to dig through. People need to be careful modifying the exhaust systems on an engine. All engines have an ideal amount of back pressure required to achieve the most power at the least amount of heat out of the engine while compromising a bit of power loss for noise reduction. There is usually a sweet spot that the engineers already hit for you. Maximize power, reduce heat and decrease noise. When you add another muffler you could be significantly increasing the backpressure on the exhaust port of the cylinder(s). This will reduce power and can also affect carburetor jetting efficiency.
The noise mat and sound suppression box are a great approach so long as the engine has proper ventilation. If you stick it in a box, the oxygen level in that box will drop and that will cause the engine to run richer in fuel. So assuring the air intake at the air filter is closest to or outside of the box would be best.
All of the better engine companies do extensive testing to maximize the output of their engines. When they run their tests they do so in varying environments such as high altitude, cold climate, hot climates. However they do not assume someone is going to put the engine inside of a box and this could have a detrimental impact on the engines lifespan / fuel consumption and performance. Ok, preaching over with now.
Thank you for the comment! I will mention all of this information in a future video and give you a shout out if that's ok with you! :)
@@soundproofguide thanks again for your content.
Good info. Well spoken.
The ideal amount of back pressure is always zero. Any amount of back pressure will reduce power since it requires the engine to do more work to expel the exhaust gasses.
Exhaust tuning revolves around pressure waves and their termination. By altering when the pressure wave is terminated, you change what RPM peak torque and power occurs at by making use of the scavenging effect to increase cylinder filling at specific RPMs. That is what hot rodders do with headers and muffler placement.
Car mufflers will flow more than enough for any small engine to not add back pressure, however it can change when the pressure wave is terminated and that can change when peak power occurs. Since most small engines operate in a small range of RPMs, 3,600 or less, a shift to a higher rpm would be noticed as a loss of power in the lower operating range because the engine will never turn enough RPMs to achieve the new peak scavenging.
Cool another slide video of someone that’s done none of what they’re suggesting and just recycled others content.
He puts his in a shed or barn.
Half the things this guy suggests he has no 1st hand experience with and the other half is down right dangerous.
So a tiny hole in your box will make it useless, but leaning plywood against your generator will greatly reduce sound? I'm confused now lol
Unlike a box, the plywood is angled so that the noise is directed downward. A box is not angled, it's just 4 vertical walls which keep the sound inside without any directional focus. So a hole would disrupt the acoustics from being enclosed inside.
You’re right. He got caught slipping.
Why don't we just design a pyramid box? it's angled to the ground while having slits for exhaust?
He said leaning boards will reduce the noise by 10 decibels. A hole in the box will let the sound waves out. You are trying to compare apples and oranges.
@@user-1A-2A These are two different sound dampenings going on here. Angling the boards against the generator deflects the sound downwards and into the sound absorbing grassy ground. If it were concrete it would not work as well. The other was a cabinet where it is designed to hold the sound waves inside the box and just like a damper in a speaker box if there is a hole in it, the sound waves will escape.
I shot my generator with a 9mm, job done, no more noise.
Also if you Let the Generator far away from your home you will have problem with loss of power. Due to the cable resistance
I would worry more about it being swiped!
The cord also has to have the proper gauge wire for safety reasons. The longer the cord, the lower (heavier) the gauge.
@@GalileonPrime Disconnect the neutral bonding wire from the frame, replace it with one of the 120V hot legs, problem solved.
Get ya one of those new fangled quiet generators. I think they are called solar panels.
What do you do at night?
Some of these ideas will definitely make the generator quiet but will also cause it to run hot with improper ventilation which will shorten the life of the generator
Moving the generator away from the house requires wire gauge considerations and becomes important ... the longer the wire ...greater the load loss. Can become very expensive.
your right JRP , father in law is retired electrician , said don't extend beyond 20 feet , with 10 gauge , my rig , 14 horse v twin 8000 watts B&S
I tried an extra muffler i had lying around first, on my Chinese 5kw diesel, but made very little difference to noise outside(generator was in garage with exhaust going thru wall outside). So found a 2 meter long piece of old lead bath drain pipe i had lying around, and attached that instead, worked well, without a meter to test though, but seemed like about 50% reduction.
I wonder how rigid iron pipe would work with a couple extra bends...
I was thinking about doing that. Like welding a second muffler to my generator
Just go buy a generator from a good manufacturer,most of these methods are hazardous and inefficient
I used to have one of those 2-stroke, 800 watt Harbor Freight generators. Chincy little thing, but it worked quite well for running some lights and fans during camping on hot summer nights.
I put the 'genny about 100 feet away, over a hill. Then a 10 foot long bit of electrical conduit large enough to slip over the little exhaust outlet with the spark-screen in it.
A small hook clamped about 5 feet down the pipe where a bungee with a metal hook was connected, then the other end connected to the frame of the 'genny to keep the pipe tight against the exhaust. Finally, a Y-shaped branch jammed firmly into the ground to support the far end of the pipe. By the time the exhaust had exited the pipe, it was barely warm. All that, and a few bits of wood stacked as mentioned. This was in a state park campsite. During the still hours of the night I could just barely hear the 'genny. I asked neighboring campers if they heard anything, and if so, if it was bothersome. Nobody, not even the park rangers could tell that it was a generator only 100 feet away. It sounded pretty much like a window air conditioner running across the street. With little load, one full tank lasted all night, and long enough into the morning to make coffee. I sold it to my brother 10 years ago. He still uses it on jobs.
Now I have an inverter 'genny. I still use the stacked wood method, but with 2 inch thick, rubberized-coated Styrofoam insulation boards rather than plywood. (Leaving openings for air and fully open on the exhaust end) Cant hear the thing at all.
ALWAYS.. ALWAYS! Secure your 'genny with a lock and chain around a tree at least 6 inches thick. Junkies & crackheads are everywhere trying to steal anything to sell for their next hit.
CHAIN IT UP!
Holy shit ..
I know this ia an old comment but i am interested in exactly what materials u used to make your "rubberized coated insulation boards". Were they actual wooden boards lined with styrofoam? Or were they styrofoam only? If styrofoam only what doyou use to keep them from blowing away? What kind of styrofoam? What was the rubberized coating? Rubberized Undercoating? A thin rubber mat? Thanks in advance.
@@webstella What I had was some kind of underlayment my uncle got from a jobsite he worked at. An insulating foam that goes under the steel sheeting. Basically, it was a panel of 2 inch thick, white strofoam with this black cating on it that was elastic and rubbery. But it looked like black cork. I have never seen anymore of that stuff since. But I never really looked for it either.
Ok I just googled several keywords, and nothing similar comes up. I was trying to give you a link to a photo or source, but I'm having no luck. The closest thing I could find was Polystyrene "Sandwich" board. But it has metal cladding rather than the rubberized coating.
As for the method I used to keep it in place, I used landscaping fabric pins. I just pinned then together in a 3-sided box shape and put it over the "genny, with the exhaust pointing out of the open end.
Sorry I couldn't give you more info. I really do wish I knew what the stuff was called.
Best way to eliminate generator noise is to put it far enough away from your home so that someone can easily steal it. Once it has been stolen, things will be nice and quiet.
The instructions for the generator I have says to leave at least four feet of free air around the unit to prevent overheating.
How is enclosing it in a wooden box not going to cause it to overheat and possibly ruin the generator ?
@Michael Miner Isn’t a plywood box a solid barrier? Plywood seem pretty solid to me. I guess that I’ll have to make a 10’x10’ shed with insulated marine plywood walls to give it plenty of breathing room. Another project.
ventilation ducts
Hey man! You'll have to install some fans/vents. I'm still in the process of designing my compartment for my generator, so I can't help you with specifics, but a dude on a forum told me he built his with vents that had small fans built in, and he somehow wired the fans in with the generator so anytime it was running the fans were running as well
@@jamesgaudreau8315 Sounds cool, no pun intended. I’ll look into the fans, maybe on on each end. Do you think that both should exhaust the air, or maybe one to exhaust and one to bring in cooler air from outside. Just a thought.
one of my employees built a sound box and it overheated after a few uses
No, no, no. Never operate a generator in an inclosed space that is large enough to enter like a shed or garage! NEVER! NO!
is this due to the air in the enclosed space becoming toxic?
I just dug 4 feet below ground and covered with plywood it worked and cheap
that is not an option when you live at sea level like i do .. most ppl put their gen sets up on a platform actually
@@rayhs1 or where I live there are boulders under the surface here bigger than a vw bug. They are building a new house across the street and you should have seen these huge boulders just under the surface.
I did that too but I left it in there too long and when it rained, it got flooded in my hole! Also when I covered my hole, it choked my generator out. I'm going for the vented box now
Dont use mdf on any type of outdoor enclosure. Its a water magnet and useless after it gets saturated.
quick safety tip. I work on powerlines and during storm restoration we love to be able to hear a generator running. If a generator is incorrectly installed it can backfeed the high voltage and kill us. When we hear it, we know to be more wary. Great vid!
TLDR: keep it loud after a storm.
You should always just be careful
My first time using a generator after a winter storm resulted in having the cops come to my house on a noise complaint and me getting a written warning that the generator would be confiscated and I would be fined if they got another complaint.
What would be incorrect installation?
@@jubhgioubgob with either an auto or manual transfer switch. This isolates the house/generator from the grid.
@@Bobaganusche72 sounds like a jealous neighbour snitched on you who doesn't own a generator
Perhaps buy a better generator to start with! A better, more commercial generator typically rotates at 1800 RPM instead of the typical home generator bought at a big box store. The typical lower cost generator turns at 3600 RPM.... do you see a problem here? You can put all the mufflers you can afford and it won't help a noisy motor clanging away at 3600 RPM. Buy a better designed commercial or long life generator turning at 1800 RPM. It will be significantly quieter and lasting much, much longer.
Never point a generator exhaust toward your home or place your generator in a garage or carport area!!.., whether you are looking for a quieter sound or not...you would be pointing carbon monoxide laden fumes toward your living enclosure
Everyone talks about inverter generators on how good they are, and how quiet they are. Well, let’s see how long they last and when they do break how much they are to fix. There is a lot more to an inverter generator than just a motor and an alternator. A lot of technology, and you know that technology is exposed to heat, cold, and humidity
Be careful about useing wood, wood absorbs gas fumes making it flammable, its what happened to my neighbor, the fire spread to his house and burnt the house down.
WATCH THE UPDATED VIDEO / MAY 2023 - th-cam.com/video/v0gik5tNxw4/w-d-xo.html
Oh, man I wonder how long before the box would catch fire with my 8500 watt genny. We had a power outage a few weeks ago and can run the entire house on it, plus one AC. The muffler glows red, you can see it at night. If you stand 5 feet from the exhaust, your legs get hot. This is at 50% load too! Imagine if we cranked up two AC! One thing I can say, enclosures do work, provided they are designed with cooling and exhaust ventilation in mind. For example, look at the Generac 7.5Kw genset. Its basically the same as a caged generator, but in an enclosure. The key though is that it has plenty of ventilation and the exhaust is piped out of the box so it doesn't release its heat inside it. I also know that the alternator in the genny has a good sized fan to suck heat out, so making sure there is good in flow and out flow is key. If you do make an enclosure, make sure the front and back, in relation to the genny, the front would be the motor side, the back the exit of the alternator where the air blows out, and some method of getting the exhaust out, and it will work. Give at least 12" clearance all around. Here is the MOST important ting, Make sure you can open it up to air out BEFORE starting it! Gas fumes can and will accumulate in the box and if you have a power starter, and you push the button, you could very well go BOOM!
thank you so much for this. well appreciated
I listen only guys who had experience and tried to work around this problem. All rest of you: sceptical criticals- you All just Shut Up!!!
You have zero actual experience dealing with this problem. Half your stuff contradicts itself. Several of your video clips swiped from other youtubers. Several tips are dangerous.
He's trying to cure diarrhea by fixing the toilet. Buy a twin cylinder inverter Cummins/Onan genset or Honda and Yamaha and Suzuki make them too(yes, they are expensive, but you can hand them down to your grand kids if you maintain them) and be done with it. What is the ONLY brand of generator that can be used in ALL National Park Campgrounds after "Quiet Hours" and all National Forests and all State Parks and all Corps of Engineers Recreation Areas? Onans. I had an Onan 11000 Emerald Series in an AirStream Excella MotorCoach and put 55000 hours on it with only oil changes and new spark plugs. When the vehicle ran, so did the Onan for the twin roof Coleman A/C's. We got better fuel economy that way, 15.5 MPG VS. 14.5 trying to use the the cab A/C to cool the rig (pulling different Hondas, Civic or Accord Hatchbacks didn't make any difference). 454CID Chebby slightly worked on(headers and Jacobs ignition replacing the worthless GM HEI), G50 chassis, 400 Turbo-HydroMatic 19" Alcoa wheels. I THINK Yanmar makes a liquid cooled des-iel inverter genset that's quiet as a baby's breath too. Look at what's at the base of the local cell phone tower for a back-up. Ex-room-mate installs and maintains those things...
confused. dont leave any tiny gaps but you need holes of sort for ventilation and exhaust. oh and best yet dont point the exhaust towards your house. do it like my neighbor and point towards my house.
lol no shit. hahaha
Two things you didn't mention is you can bury the generator and you can run the exhaust into a bucket of water as long as you leave a small hole for backdraft..I have used boards to silence one and it worked really well...also one thing you said that made me laugh was you could get a battery operated fan to use in the shed....not like there is a huge generator or anything in there to hook up a box fan 😊
Haha I also caught that battery-operated fan comment.
How small of a hole for backdraft?
2:27 the guy running the table saw doesn't know what he's doing to the point of endangering himself and people behind and around him. After running a table saw for a minimum amount of time, it becomes evident as to why. This tells me that this guy has almost zero experience with a table saw. I'm not even going to waste my time explaining it. Other than that, this video was beneficial to me. Cheers
Exactly
I have a predator just like this. Muffling the exhaust is of zero effect. The noises overwhelmingly from the motor crankcases. The enclosure has merit. Exhaust muffling is simply ignorant crap.
Exactly. Exhaust noise is a small percent of the noise. I dug a 5x5x5 hole in the ground , covered it with a roof and big exhaust fan, and I can barely hear my genset now.
I worry about overheating it with an enclosure. Trying to use my welder in my garage but feel bad for the neighbors..
I would have the same concerns, it's bound to build it heat Using the zombie box, and I'm sure that would shorten the life of the generator.
@@sambiscits6711 Heat rises and there are honeycomb vents seen in the pics and the top exhaust vent. I hope for the sake of those expensive gens.
@@FrustratedBaboon I've recently had a Full House generator installed, and I'm looking into ways to mitigate the noise, I'm looking into something I can build myself.
@@sambiscits6711 I'll build my own as well. Gonna spend extra for 500+ CFM exhaust fan and air filter so that the internal temp is only a few degrees higher than outside.
@@FrustratedBaboon Sounds like a great idea, I'm going to have to come up with something like that also.
price a Zombie Box.. you will deal with the extra noise.
Don't run your extension cords any longer than necessary and if you do need to, make sure you match your gauge size to the distance and load to be used. Running too small of an extension cord a long ways could overheat, causing damage or even a fire.
It also makes the devices consume more amps... You're actually consuming more power from your generator cuz part of it is heat. I found out a long time ago my generator couldn't start a circular saw with too long of an extension cord..... But with a short extension cord.. no problem
Yes it's called resistance
Put my air compressor inside an old refrigerator, I can barely hear it now.
That's borderline genius!
We stuck ours in our old abandoned mini van, we just drilled a small hole in the gas tank to get rid of the gas. Keeps rain off it. Works good! Can barely hear it.
Nothing more annoying than campers with generators.
Just buy a decent whisper gen
Bare in mind the longer the extention cord you use the higher voltage the draw will be on your generator.
You need a thicker cord. If you are going 100 feet, get a 12 gauge cord. More expensive, but it won't heat up and it won't offer as much electrical resistance. It's not just a matter of how much it taxes the generator, but also how much power loss you have at the far end.
You use the proper size cord for the amperage you're feeding and for ever 50' extra length the cord is, you size up (bigger) one guage. For instance, if you're running a standard 15A circuit at 110-125v up to 50 ft you would use a cord that is 14 guage and if it's between 50' and 100' you would size up to 12ga etc. 16 guage is good for 10A at up to 50 ft.
I rigged my Duramax dual fuel generator with the gen turi exhaust system,which takes exhaust noise up 16 feet thru pipes,and it also takes heat with it,so noise,heat and fumes are up above our campers and others,also have a box that Al this goes into,so on full load noise is around 42 decibels.
Please do a video of your setup. This sounds like the complete answer.
How do you allow airflow??? That thing would burn up from no air
DO NOT RUN YOUR GENERATOR IN A SHED.Manufacturers of generators strongly warn against running a generator in a shed or garage under any circumstances, even with the door wide open. Carbon monoxide is very dangerous! You can't see or smell it. Eventually you will need to go into the shed to add gas to your generator, and it will be full of CO. Whoever made this video does not even mention using a carbon monoxide detector. DO NOT RUN YOUR GENERATOR IN A SHED.
Thank you handsome
At least it will be a painless death.
Why would a video about sound/noise reduction have annoying background music playing over and over??!!
Some people would complain if you GAVE them an old $100.00 bill. It's just something to bitch about.
Or you can skip all that hassle & buy a Honda Generator. :-)
Honda’s are quieter.
... and pay a leg and an arm for it ....
ttdelta2 I’ll bet you even eat cheese & macaroni. Don’t you?!
NM. Gotta run. It’s raining dogs & cats. 😝
West McGee Nope. Allergic to them and to stupid answers.
If you buy 4 of them (mortgage your house in doing so) you'll have a decent (not large) sized generator. Ridiculously high for what you get.
In the case of using a box , what about the overheating ?
Car muffler will not work because it need large amount of air to cancel its own sound. Don't spend $200 on "gen-silencer". You can get same result from $15-$30 exhaust from Amazon just type "generator exhaust". Don't forget to use 90* elbow when connect to new silencer.
Great advice! Thank you!
Help me square the circle: "don't leave even the smallest hole in your box, it won't work" with ventilation
Indeed.
You would need to baffle the air intake and exhaust. Keep in mind sound waves travel in a straight line.
You need to seal up every crack and hole, then cut a 2 -16 x 16 inch holes for a vent and fan.
All these techniques to quiet genny are out the window if we get attacked by those monsters from " A Quiet Place" lol!
😂😅😅😅 They would destroy the generator. Those monsters were crazy!
Just buy a 100 foot extension cord and put your generator in the neighbors yard. Ahhh, nice and quiet now.
You increase resistance the longer you make the cord. Plus a cord that long with that thick of Guage would be expensive. Thought about it though. Lol
Most of your sound is not coming from the muffler it is coming from your stater
Making a wall exhaust for the fumes to leave the building......my wife will think I'm making a Glory Hole
Lmao.
My Dad said a car muffler would kill the horsepower of a generator, and that is something to think about too.
Big mufflers never work. It’s the fact that a small 4 cycle engine has to rev to 3,600 RPM it’s the engine itself and the surrounding parts. VIBRATION IS THE REASON FOR THE NOISE, ALSO, SIZE MAKES NO DIFFERENCE I OWN A GENERAC GP 17,500E ITS A 992CC V TWIN AND WEIGHS 400-500LBS ITS LOUDER THAN ALL OF THEM!!

Or buy a Honda generator
sound proofing a generator like this can cause damage to the Generator . 1 it can cause the generator to over heat .has to be vent very well then you lose the sound proofing . also alot of gens have alot of plastic's on them that can warp over time use due to the heat . intakes . carbs can be plastic . elec control are plastic that do not do good in the heat . most Gas gen are loud . propane gen run alittle smother and alittle more quieter then gas . but if you do this you do it with a bad risk .
risk
over heat
wharp plastic due to over heat
elec failure due to over heation
elec control system has silcone base to weather proof elec that can melt an turn it into a 700$ repair . an sometimes parts you can't get specailty with honda generator's since Honda loves to not make part for engine's or generator parts for to long . 10 years i think is the max .
also you can blow your self up . due to the gas tank being mount on the generator .
SO DO AT YOUR ON RISK! IF SAY IT CAN BE PUT INTO A BOX PUT IT IN A BOX OTHER WORD'S THEY MAKE QUIETER GENERATORS
The best way is not to buy these cheap units they all run at 3600 RPM buy a Onan they run at half that RPM I own a 28 KW unit that is powered by. 4-53 Detroit 2 stroke Diesel engine I bought it for less than some of the gas units it’s 3 phase I bought a transformer to convert it’s out put to 240 volts 1 phase along with a big transfer switch that runs the whole farm for $300 I used a semi muffler on it it is in its own insulated metal building you can hardly hear it I have a used semi 100 gallon fuel tank that feeds it along with 1500 gallons in the ground tank for the the equipment. Shop around you can find bargains and do not forget army surplus you find any thing look up government planet.
Just to correct the information, no small engine is splash oiled anymore. Flathead engines will not meet EPA requirements and OHV requires an oil pump. The easiest way to deal with a generator is to make a corral of filled concrete blocks in which to run it. It only has to be as tall as the generator.
Just buy a variable speed, quiet, inverter. Don't do this dumb shit! "Lets cover gen set with plywood". So it will over heat? Big muffler is waste of time! Buy a 500' extension cord?
The muffler one is a joke and dose not work, I seen a video of a guy who repairs generators and he used a sound decibel meter and that there was no difference in sound with a car muffler and without a car muffler added to it. So DON'T WASTE YOUR TIME WITH IT.
basically, build a sound box. Lots of insulation.
How exactly are you supposed to be able to return a muffler after you've welded it to something as you suggested ???
Also a zombi box for 1K !!! ... Now I see why you never purchased one like you said you were going to in your last video about generator noise. Out of curiosity you had to know what the price was so why didn't you want to share it with us ? Because you know that it would be a complete waste of money and one can make one themselves for a third the price.
This is the soundproof guide channel 😆🤣
2 in Styrofoam 3 sided box and lid. Leave the exhaust end open facing away from your home . Use velcro and bungee cords to assemble. Easy to take down for storage .
A Zombie Box or an enclosed soundproof box sounds like a good idea, but what about all of the heat? Where does it go? Out that small ventilation hole. It might work for 20 minutes. But after an hour or so, it's going to shut down and most likely destroy the equipment. Generators are air cooled. If there's no air getting into the enclosure, how does it get cooled? If you figure out the cooling issue, please let me know. I would keep one side open and aim a large fan at the generator. Unless you don't like your generator, then do whatever.
Compresión sounding like air-conditioning like police and security cars have except getting stuck or chasing somebody the compressed thing off by its self and loudness comes out automatically or if it has bad muffler senior trucks nowadays and delivery trucks and cb performance and stock engine ones and school buses delivery trucks same thing but made of stroker but bigger boxer Volkswagen custumized deisel turbo and desil stock engine or all four in some they compress the noise sounding like normal truck and Volkswagen cars Volkswagen street Volkswagen and trucks like normal sounding but air-condition sounding tinging
There’s ibc totes on marketplace for $40. Im gonna get one and cut top off and flip it over mine. Experiment
Obviously - buy a quiet model first, but after that use the landscape to your advantage - put in a dry ditch or behind rocks, or dig a pit and use the spoil to fill sandbags or fabric bags and place around it like sand bags. Stagger an entrance for access and exhaust as sound does not travel around corners well. Then use an old soggy plywood roof, or use earth on top. Parking it on planks or a board supported at the ends like a bridge will prevent the ground vibration problem.
After watching videos on this subject with real life professionals advise I would say this video has fairly bad advice.
Choking off both the proper ventilation for the generator as well as the cooling space required is a sure recipe for trouble.
So the blap blap blap noise is from the crankshaft , not the explosion in the cylinder. ? I have a car muffler and all you can hear is the intake noise so . Oh my god now your saying ... oh i quit ...nvmd
I was thinking your first idea but what really happened with the cooling of Generator ?. We have problem there.
Yes, you can have a problem, the engine could overheat. The engine operating temp could be as high as 200* f in that box with no problems. However, the generator wiring insulation maybe only rated at 105*c or 220*f
Any box should have fresh air only duct, vent, opening to cool the engine and gen head made in such a way that the intake air does not mix with the heated air under the box. The box will pressurize and will need a vent back out. An exhaust fan will not be sufficient to keep heated air from recirculating though the engine and run too hot. The engine carb intake should have new air also. This is how Enclosed generators work. The front of the engine and the back of the gen head is where air is pulled in.
Bravo.........the box needs 150cfm air blower......for cooling...........best .....pipe the exhaust into 5 gallon metal bucket filled with water......like a boat......cheers
Fans really dont pull many amps. Get one and plug it into the generator! Preferably have it exchange air also.
Lol, I hope zombie fires their engineer. Radiant barrier around a heat source when cooling is benifical ? Ha ha ha. Unless it's used in the south pole why?
Squared off walls don't help with sound either. They should start with something more trapezoid.
Your gonna be have to disable the carbon monoxide unit if you have the a generator with this. I was just putting Oly wood around mine and it shut off. So I just disabled the carbon monoxide unit.
Cover it with expanding foam spray. Or just put it underground.
There is no "sudden increase of severe weather." Throughout the history of the planet, weather patterns change.
You first say don't leave any holes as sound will escape. You then immediatley say to make sure and leave vents.
If you add flexible hose in muffler for get generator in car, its noise level is low.
Any holes you make in your shed are going to allow sound to escape. The holes need to be covered with a baffle to break the sound up before it reaches open air. This includes air intake and heat exhaust fans.
Isn't a gen 'silencer' just another name for a 'muffler'?
When building a sound-proof enclosure, you should think in terms of reflective, absorptive, and inert layers. Innermost is reflective, next is absorptive, with the outermost inert. The inert layer prevents the engine's noise from being transmitted into the surrounding environment. See the comments about sandbags below.
Easy answer too this is get a predator 3500w generator its stupid quite compared too other generators and its very efficient on gas
The link for zombiebox doesn’t work
Cop cars are demolition derby loud Baldwin engines but are quieted down by same method it's called ringing down
Don't ever put a fuel burning generator inside a building. You will be dead almost instantly if there is ever a leak.
A car engine woulx mak you deaf without a muffler.
No! Number one should ALWAYS be about the fumes. Are you crazy?
Or you could say top 1 tip.. build any kind of enclosure around it. Lol ok
Not “any kind”
@@westmcgee9320 right right. Like dont build on out of paper or cloth and several other obvious materials that wouldn't help. Like toilet paper, or silk.. but basically any kind of wood enclosure. The thicker the better.
Even plywood now , 50$*++ per sheet , not cheap solution
When your power is out why would you care how loud the genny is? You got power. That's all that matters. Neighbors can hear it and sit in the dark with jealousy.
Storage tote and something for insolation. Pine needles? Pillow stuffing in a mesh?
mine is a 9500 watt with 12000 peak watt and it is loud. It does work though
Mostly not at all useful information. And sometimes silly. And put a long extension cord on it? Any idea what gauge wire you would need for 5 or 6 Kwatts to extend it 100 or 200 ft? VERY BIG!
Even then you would experience a drop in amperage. 10 Gauge is expensive.
