In today's video we are going to cover the 5 Acoustical mistakes most studios are making. They are as follows:
1. Low frequency management,
2. Room set up,
3. Absorption rates and levels,
4. Floor and ceiling,
5. Size and volume.
I go into studios all the time and I am constantly amazed at how many are getting one if not more of these items wrong. It's better to get these issues correct at the start of a new studio build than it is after. That is not to say that we cannot fix problems but in the long run its cheaper to solve at the start of the design phase than it is at a later stage.
So enjoy the video and let me know if you have any questions or issues you are facing in your current studio or a new build you are thinking of, and I'll be happy to help answer them.
Thanks

Love the way this guy is so brutal and matter of fact, he doesn't sugarcoat anything. The truth can be a tough medicine sometimes!
M, The problem today is that less and less people subscribe to the laws of Physics. Speakers produce energy. Rooms hold energy. Its all physics and you have to follow the rules. No compromise. The compromise occurs when you have all the basics done correctly. You have right room size for usage, the correct speaker/room marriage, the correct speaker to side wall distances for usage and a host of others. Once you get the basics correct, then and only then, can you experiment with creativity.
These lecture style vids have made the whole subject of room acoustics immensly interesting.
You tubes finest,
Fantastic video! This info is GOLD!
amazing information!!
It is so hard for me to focus on what you are saying because there are compression and reflection artifacts in the recording that severely interfere with the coherence of your voice. It makes it very difficult to believe you care about the quality of the sound reproduction when the sound quality of your recording is so bad. Try listening to your videos in one of your critical listening rooms some time.
Hi bill garrett
Yep guilty as charged. We outsourced the production of this video (and a couple of others) to a new team. The mics they used had a hiss on them so this was their repair job. Suffice to say we won't be using them again. Unfortunately, due to my work schedule it was either use these videos or not publish anything for a 6 week period so we decided to go ahead and publish so people could see the content and hopefully forgive the production issues. My apologies, its not the standard to which we normally adhere and have a new team all set for 2015.
why wouldnt you just overdub the voice and put a little message why you had to overdub the voice , the audio just makes you company look bad when its all about sound and the sound in the video is terrible
The problem with overdoing noise reduction. I've learned the hard way that a lil EQ is a much better solution than using a bunch of noise reduction.
So what you are saying, is if a fireman's home burns down, you will not call the fire dept? Oh ok.... That makes sense......
I'm a working sound professional in broadcast. I don't mind what the video sounds like. I'm here to advance my professional knowledge of acoustics not to enjoy quality media production. I know a couple things -- #1 the person in front of the camera can never also be dialing levels and usually isn't setting the audio up in any way. He just lends his voice. #2 videographer microphones (especially poorly placed inexpensive ones) hear a space much differently than ears or even studio microphones due often to interference tube (shotgun) designs and how they react to nearby reflections, so I wouldn't judge the sound of the space by this example. He is right in front of a huge board after all. #3 I've been doing this for more than a couple years and I learn something new in every single one of the Acoustic Fields videos. I know sound professional advice and free don't often run in the same circles. Thanks for the awesome videos!
I am so grateful for the knowledge you have shared here!!! The headache you speak of is the one I am having now!! :) I am trying to setup a tracking and mixing space in an attic apartment. Angled walls. :(
Hi Michael,
Send me photos and calculate angles in photos. Let me see if ray trace can help you.
Invaluable advice. Thank you
Great Video, I have no problem hearing or understanding the video
I've subscribed more than 73 channel of my intrest on TH-cam...your channel surprass them all !! Thanks a lot 👍👍
we watched the entire video and it was great. we're sharing it with all of our peers.
What you said about being able to have an emotional involvement with the music is right on.
Having a room that may never work because of size and dimension is a hard pill to swallow for many project studio owners.
We have great equipment and years of experience. we can track in our studio but for mixing we must go to a pro environment.
+nublackmusic I tell people every day to find new rooms. We all owe that to the music. Especially, if you are making your living in it. The reason for this is that the treatment required in order to smooth out the acoustical issues within a small room, will leave you no money in your bank account or no place to sit.
Wish I had found this video before commenting on another of yours earlier today. This answered most of my questions. My wife and I just started escrow on a home and I had my room all picked out.....until now. lol. I better get used to TV dinners.....haha
Dennis you are a genius and i can't wait for more people to learn from your
expertise and help the little guys make better recordings....cheers
Thank you Rick Spyder Much appreciated. Thanks for all your support, much appreciated.
Dennis
Thank you for another informative video. The theoretical information you give is very valuable. I understand some readers don't understand that you cannot give all the information you have labored and learned throughout years of research and practical experience and you cannot just give specific instructions or data on their rooms unless of course they get your service. People forget that you are in business and some of the specific information that they are asking frankly should not be given for free. Also what ever free information you give and explain is more than enough.
Hi Henry, Thank you for your observations. Our data base of built and measured rooms goes a long way to assisting clients with the correct room size and volume for their particular audio usage. From there, we can address any barrier or treatment options. Our DIY series of diffusion and absorption products can assist those clients that are on a budget and for those who do not have the carpentry "gene" , we can build both absorption and diffusion units for them.
Great Video!!!!!
Might be a good idea for people making educational videos concerning sound, to actually capture descent sound for the video. It should be quick and easy for some sound pros. You could stick a zoom handy recorder in the room hit record and it would sound way better than this.. just saying. Good info though..
If you focus more on content than presentation value you might learn more.
Great Info. I was totally absorbed.
W, Thank you for your support.
This really put it into perspective.
Hi David, Glad it helped. If you have any ideas for topics you would like to see covered, just let us know.
I Love your Work.
Thank you very much!
Thank you, your videos have shined a light that I couldn't see before.
I've spent years learning instruments and engineering skills.
I understand the concepts here but find it hard to fix my low ceiling,corner speaker position,angled walls with a hallway @ 90degrees at the edge of my rear wall behind the mix position, which has a huge 50/60hz bump when I walk into the hall.
I use it as a reference for too much or not enough bump.
I know my room is not correct but thanks again for sharing your knowledge, you're very kind.
+mebangondrum Thank you. I will need more information in order to assist you. Go to this link and fill out the required information. www.acousticfields.com/free-room-analysis/
I love how passionate you are about the quality of the setup rather than the aesthetics of the setup. Thank you for making this video!
watcher of your great videos for some time ..Out of interest,what would be the smallest dimension room that would still work with acoustic treatment for a control room in your opinion
Hi Rockit, Here are dimensions from my data base that is a good break point for material, labor, modal and RT-60 "costs" 17' w 12' h x 27' l. Use this size as a minimum. Sound quality improves with each 1' distance increase from these dimensions.
Great video. I am building a mixing and production studio in Koh Samui in Thailand. Need all the help I can get. I bought the DIY resource book but would honestly love a quick chat if possible.
what should i do to my room to fix the bass as its to loud ,i have some bass traps ???
One of the great features of proper acoustic treatment, it, generally, doesn't wear out , "age", or become obsolete. It can't really "break" or suffer from AC power surges and sags. If a guitar player spills a beer on the treatment, it doesn't end the session.
Respetar las distancias exactas entre parlantes, oyente y paredes creo que funcionaria si tuviéramos una sala simétrica, pero si nuestra sala es "el living" u otra pieza de la casa, donde existen diferentes arquitecturas, muebles, aberturas , etc, respetar esas medidas no necesariamente traería buenos resultados.
Love your take on things, I'm currently working on a remodel project. Studio is 200 feet from a main rail line, 50 freight trains a day. We have steel corrugated siding, 2x8 pole shed construction, R21 glass insulation, 1/2" drywall. AKA train wreck for a studio. Well that has to go... I was going to tackle this from the main stream line of thinking and materials, until I landed here. You have confirmed my suspicions that most general contractors are clueless regarding low frequency sound (trains with no horns) and what it takes to mitigate it. What is you take on large glass windows. Example Three 48 tall by 60 wide commercial double pain Aluminum frames. This is my biggest concern. I can replace them or even add a second set to double up. I don't care about space and can frame thicker walls Regards Al
All noise must be measured. The barrier you build is based upon the frequency and amplitude of your particular noise. Without the noise numbers, you are just guessing and guessing with noise issues is failure. Fill out the information in this link:
www.acousticfields.com/free-room-analysis/
not only are the floor and ceiling a problem but most studios have a parallel surface with their fav analogue desk
so now there are double the reflections even before the walls are heard.
Hi Rick Spyder
Great comment and yes that's correct, only that console reflection is so powerful the science of acoustics refers to using its own name: "comb filter". It produces a phantom image or sound as a result of the near field, time delayed, energy hitting the console and reaching our ears.
Thanks
Dennis
I can hear two voices, you have lavalier and the camera mic in the mix. Someone forgot to mute one audio channel in the video editor. When you move your head, phasing accures. Right?
+BadHead Rock (Blues) Spend your time focusing on understanding the concept instead of the delivery system. You music will thank you.
I’m thinking of setting up my listening room on the diagonal to see what happens. That is, speakers and listening position are not on a line bisecting the room but instead going on a line from corner to corner. Maybe even at an angle not quite diagonal, just to get acoustic modes more random.
J, You could try. However, without knowing your room dimensions, this is problematic. Make sure your side wall distances are equal.
Hello dennis thank you for all the videos. Its really great and helpful, Im learning a lot from your videos.
And I have a question for you about room size ratio (WHL). Can you tell me what kind of ratio are good for controlroom and whats bad?
You can tell me just approximatively. Or if you have time, you can tell me in details.
Thanks.
Han Lim No problem. For control rooms, 17' W x 10' H x 23' L is a great start. Larger is better but this should be a minimum ratio of WxHxL for a control room, home theater, or listening room. I will put this on the list to answer in next weeks Google Hangout to give you a more in depth answer.
Thanks
Dennis
Thanks!!
Hi Han Lim I recorded an answer to your question in this weeks Google Hangout which you can see here th-cam.com/video/nHy7qmHEl9k/w-d-xo.html I hope it helps. Please let me know if I can be of further assistance.
Thanks
Dennis
I have gik acoustics basstraps in my room, however the walls on all sides have built in ledges on them, so centering a basstrap on the wall is impossible. How can I work around this? Would putting them horizontally work? Thanks.
Hi Skrenja, I will need more information about your room to assist you. Fill out the information in this link: www.acousticfields.com/free-room-analysis
Best advice: Put the look last...put the music first! It's easy to get carried away making it "look cool"...this is such great advice and a great video! Thank you!
B, Form + Substance = Essence
Hi, I just started yesterday to see your video, and they are GREAT, so great that depress me. I'm a 20 year old guy so I live with my family, in my house. Now we will get some new rooms for our home and I want to create a little studio for music production and super basic mixing, the problem is that the room is only 3,9m W 2,9m L and 2,7 H ( sorry I'm italian so I'm not great with feet and inches ). I started to make a plan for the room, placing thing there and things there, the equal triangle etc etc Then I started to watch your videos, and I understood that my room probably will never sound good. Now, should I continue to plan the room following some basic acoustic advice ( triangle, 38% for listening position, symmetry ) or I can just put things to make them functional for the creation environment ? ( for example in the actual plan I can't open a window )
Sorry for my bad english, hope to receive some answer, no matter what it will be :)
Hi S, Room size/volume must match your intended usage. Go to this link and fill out the information required. Photos of all room surfaces are helpful. Lets look at the frequency/amplitude issues that we will have to treat. After we have identified the issues and their treatment, we can then make a determination. www.acousticfields.com/free-room-analysis/
Hi, I have a question. if I’m not able to acoustically treat my room, will investing in a isovox 2 booth be a great alternative ?
K, I am not familiar with this product. Different room usages have different requirements.
Is this more addressed to having a room with monitors while mixing, or actually setup to record in?
Hi Michael, The "sound triangle" is an "triangle" with speakers / listening position at equal distances from each other. The issue then becomes where to place the triangle in your room size and volume for smoothest response.
Dennis which materials are suitable for blocking an extemely very loud music in a night club from escaping outside? can you recommend and link me to see materials which can be able to block low frequency escaping outside of a night club?
+CONGA MUSIC You are referring to barrier technology. If you have a noise source ( night club) and a receiver ( police), you must erect a barrier between the noise source and the receiver. The type of barrier you build is strictly dependent on the frequency and strength of those frequencies (noise). You must quantify the amount and frequency of noise that you have before you build any barrier technology. Building a barrier to manage frequencies (noise) below 125 Hz. is drastically different than building a barrier to stop noise below 125 Hz.
Wow this info is priceless.
I have a room that is W 11'-10" x L 21'-6" x H9'-7" without any windows. The walls, floor & ceiling are in concrete with only one door. I guess that room is a nightmare to treat right?
The room will be used to record drums and mixing. Since I want to take advantage of the space to have "room" in the mix, once I record I guess I can make small the room to mix by putting removable walls behind me?
What can I do? The dimensions are right to record and mix drums?
Thanks...!!!
Hi Gamalief, Fill out the info. in this link and lets look at your room issues. www.acousticfields.com/free-room-analysis/ We will compare your room to our data base of over 100 rooms built and measured. We will identify unwanted low frequency pressures, their frequencies, magnitude, and location within the room. Once quantified, we can treat with the correct sound absorption/diffusion technologies. Middle and high frequencies treated next.
JUMP on ACOUSTIC FIELD offering man . That is GOLD he is offering. Just buying a Spectrum analyzer (the cheapest made) and doing the calculations would be about a $500+ tab
@@AcousticFields I think that you guys really the best option to go with, but sadly ... I'm too far away to benefit from your services, but I'm going to fill in the form anyway.
I’ll take that room. With sensible treatment you’ll be fine.
I am starting to build a room in my back yard, do you have any advice as to optimal sizes. Building in wood. Thanks
Did you find any info that could help me do the same :)
@@ian.new.life. if you follow Acoustic fields they’ll keep you right
your sound on the video certainly was not done with any sound engineering techniques!!
Hi Alejandro, If you focus on presentation only, you lose sight of the message. The value is in the experience and knowledge behind the message.
Give em' a break Peak, they're providing great information, FOR FREE!!! how could you call it disrespectful...
Noom word! To me it's almost has the opposite effect. It's like the crappier it is, it somehow makes it more believable and genuine to me. I don't really care about the presentation, the info is super helpful, thanks Dennis!
It is still hypocritical of you to teach us about audio when you deliver such horrible horrible audio for your video....
He is talkin about acoustics not audio
Hi, at 1:38 what do you mean by rates? Is that the frequency rate you are talking about? Presumably levels is the SPL? Thanks
Rate is how much is absorbed at each frequency. Level is how low the technology starts to work at.
@@AcousticFields Ah great, thank you, I misunderstood. So, rate would be a decibel reduction value for a particular technology (or rather particular useage of that technology) for a specific frequency. Is that correct? And, when talking about 'level' being how low the technology starts to work at, do you mean low as in what SPL it starts to work at? Thanks again.
gold
What are your thoughts on Anti Mode devices to take care of the low end?
I have DSPeaker's AntiMode SII, and the difference it made in both movies and music in a 5.1 setup was huge, after it takes away the peaks.
I only have a room that is 10ft w x 10ft l x 7ft h, with B&W CM10 S2 Fronts, with matching Centre and Surrounds {all biamped} with an SVS PC2000 Sub, via a Yamaha RXA 3040 and MXA5000 power amp... so a tonne of power in a very small space!
Hi Paul, I know some designers that have had limited success below 100 Hz. I do not have any personal experience with phase inversion electronics. You need to find another room. These are the worst three dimensions I have seen in a long, long, time. There is nothing that can be done to improve upon these dimensions.
If you mean inverting on an electronic level, then the AntiMode doesn't do that by itself {that only needs to be done if using 2x subs}, otherwise the only inverting that can be done is via the AVR when you select the XO.
AntiMode does great at EQing the sub, then you run YPAO after and the results combine, and given the small space it's all in it sounds great to me, not boomy at all; just nice, tight, well~defined and punchy!
Hi Paul, Send me a response curve of your room with and without electronic manipulation. Lets pursue this line of reasoning for our followers.
So what if i use safe and sound and make it 9 inches thick will it be able to absorb blow 100 herz then?
Yes, but it wont have rate. It will have level but wont absorb at the proper rate for music and voice. Music and voice can never be treated properly using a building insulation type material that was designed to keep our homes warm or cool. Level is the resonant frequency or how low the unit will go down to. Energy above the design level will be absorbed but energy below will not. Rate is how much energy the unit can absorb at each octave band. Is it a linear absorption rate or does it have spatial irregularities in its response. Remember that music and voice and building insulation do not mix.
ear opening knowledge
nice
I've got the worst room for acoustics.
Wall on the left 3' and a open rightside to kitchen door 12.5', open ceiling 9' fall if fine except might get a pad for under carpet.
R, You must have equal distance to each sidewall.
Your tips are very useful. Tho, how is it that your video sound quality is that bad? For a sound acoustic lesson channel, it's odd.
Focus more on content than production value. What did you learn?
@@AcousticFields No problem about the content, it's great!. Il watch a lot of your stuff ;)
@@xperiencerecordz What did you learn?
I've watched three of your videos, now. It is educational but, not addressing my concern. My concern is for an office environment. A law firm with several offices along the perimeter wall of the high rise glass/aluminum exterior wall building is asking me to "insulate" the offices from each other.
They are interested in damping voice transmission. Their corner offices are good. Those metal stud walls go to the concrete deck above and have mineral wool insulation floor to deck.
In trying to retrofit the remaining offices, we insulated with mineral wool batts over the lay-in ceiling to no avail. We then, blew in fiberglass (attic type) insulation into the wall cavities (again to no avail).
We next are to extend the office walls to the deck, remove the gypsum board, install mineral wool batts, and install new gyp bd. This will bring the walls to the same construction as the corner offices.....I think. We will start with one room to see if it works before we do the other twelve.
What are your thoughts on types of insulation (mineral wool, fiberglass, fiberglass SAB)? Maybe unbalanced wall construction (one layer of gyp bd on one side and two layers on the other side)? Or maybe use resilient channel on the existing metal studs before we apply the new gyp bd? Again, this is just for office environment phone calls (or people meeting) voice attenuation/transmission control. This is not a sound booth.
You may want to look for mid frequency absorbers mounted to the top ceiling of the rooms. They typically are made from 1 inch thick wood having many drill holes of a high density with about a third or a half inch diameter covering about 20% to 25% of the hole surface. These plates have a typical distance of a bout 5 to 10 inches from the ceiling rigid wall. Sometimes the gap is damped with material. This way waves go in and are "killed" because of turbulences around the holes.
ralph sampson look into high mass vinyl
Seen people building DIY vocal booths either using -wood sheets or - drywall/sheetrock. Which one is a better sound barrier ?
H, It depends on the frequency and amplitude of the noise you are trying to reduce the transmission of. There is no good, better, best. Everything used in a barrier is dependent on the frequency and amplitude of the noise source. Material density is critical but so is the construction methodology.
Hello,thanks. It's vocals of different voice styles, metal growlers, rappers, etc. Pre made commercial vocal booths like the "Whisperroom" are obscenely expensive for a regular person. Their walls look so thin. I wonder what kind of layers they use, but really no need to make walls as thin, just need function. I have to be quiet in my apartment or i will get in trouble ! This is like a s.o.s question, lol.
H, That is the noise source inside the room. What are noise sources outside the room?
Depending time of day, some trucks and screaming but i can choose quiet hours for serious recording out of creative/practice time.The main thing is to not disturb thin wall/floor/ceilings of an apartment complex, must avoid a witch hunt, not easy being a creative...Not sure i care for complex richness of the audio. Average/good, ok would be fine, i am running on a budget.
H, What floor are you on?
is there an example of space or room that you make that avoid of that 5 errors? create a video differences in A / B..
Hi Amar, Good idea and topic. I will add to our video to do list. There are 42 ahead of you ,so probably summertime. Thanks again for the topic.
nice, i will watch...
Why don't sound engineers in studios just use quality headphones? Removes 100% of room acoustic distortion/interference problems in one go! :-) And you also get to monitor the music in the way most peeps listen to music these days anyway (I know this wound not work for multi-channel sound mixes or playback)
G, I know engineers, classical music mainly, that use headphones almost exclusively. Others that I know use both headphones and monitors. I believe it depends on the musical genre.
@@AcousticFields I use headphones all the time for mixing and get great sound cause the room is not in the way but I do check to make sure everything is right on my studio monitors and it usually is and I mix in mono that really helps me separate the frequencies.
sir, I listened about twenty more videos of yours, these are all theoretical. Is there any practical videos, please advise. If not it will be highly helpful if you post.
+Gsengottaiyan Gurusamy no is not. for the practical stuff u need to contact them and pay. just business
This is what the man has to sell, this is a sales video you listen to from a man who has no idea what hi-fi acoustics is really about.
cool
Too many negative comments on the sound quality of the tutorial and hardly relevant, it's the information quality that is important
For talking audio/acoustics the audio here is pretty horrendous Dennis. Sounds like recorded through a phone.
That being said, I've watched a bunch of your videos and you really know your stuff. Thank you very much for the info.
Noted!
was about to say the exact same lol
Whats up with sound quality ?)
Budjum Pavel We had an issue with the sound card in the camera so we're getting a new camera this week. Hope you can still hear the message in the above video.
Cheers
Dennis
Acoustic Fields I was just about to post how ironic it is that the sound in this video is terrible. :) I hope you get things worked out!
Am I wrong or is he pretty much saying that the set up has to be in perfect symmetry but wouldn't it make a square? Therefore creating the same effect as a squared room. I'm so confused. :(
+h1de Room size and volume need to be considered along with the amount of energy and at what frequencies you are playing in the room. We like rectangular rooms because they are predictable and consistent in the way they react to lower frequency energy. They are also better for middle and high frequencies because the distances are defined and make the time signatures of reflections from their surfaces easier to manage. As a general guideline, make sure the length and width vary by at least 25 %.
Awesome! Thank you, you guys are amazing!
you mentioned the ratio of width height length but did not give any information can you expand on that idea ???
+Kevin Boyd There are room dimensions that can minimize unwanted pressure issues especially low frequency pressure. If you choose a room size and volume that minimizes, you can save money on treatment technologies. Dennis
I'm sorry your not telling me anything I don't know or have learned from your video.still I have no idea how to know if my studio is the right demonsions. it is 25.7 ft long,12.8 ft wide the ceiling is 6'11' my question is, is it a good room size. how do i apply the bonello equation or graph?
+Kevin Boyd
He already answered your question in another video. Check the vid response to Han Lim's question further down. He basically said anything less than 14ft width or length is problematic and ceilings less than 8ft are problematic. He said 8 ft' ceilings which are standard in north america is the worst dimension for acoustics. Does that give you some idea now? It's quite depressing. I'm in the same boat my room is 23' x 10' x 7'-6". Unfortunately that is the best room I have in my house. Guess im gonna need to do a lot of treatment work!
thanks
Really enjoying the tutorials, but there's an echo or delay in the sound, which is somewhat disturbing.
Hi Broedwick, Thank you for your support. Check your U-tube audio quality settings.
the video just has a really bad sound quality, same here
Look man you can mix in headphones so you don't have to worry about the room then when the mix is done check it on your studio monitors.
B, Headphones are one option. However, most engineers want to know how their mixes will sound in both room and cans.
I don't get this not hearing 30Hz thing because you don't have a 37' room. I mean if this is true, forget about headphones, right? Really? I'm stuck in a room 12' x 17' (treated) and I can hear everything balanced and in context just fine. So...
W, If you take measurements in your room, you will see the issues you are not hearing.
Acoustic Fields thanks for replying. Like you said "we tend to hear laterally" and I have for years treated ceiling and floors. I have used the 1/5th rule when placing speakers and seated positions. When tuning the room using pink noise and sine wave. My aim when conditioning studios is to make the sweet spot as big as possible. If I find a sub frequency that's a noticeable problem at the rear of the room, I find the frequency length and then design traps that absorb at a harmonic and a resonant level and, as you said this is where the roof comes in handy for making the low end nominal and tight.
ALRIGHT A PROFESSIONAL! Most of these amateur builders FREAK out when I tell them that a booth window requires at least 3 panes of glass (all different thickness) floating in a rubber frame and the frame held to supporters with isolator.
That the glass closest to the studio needs a VERY specific angle and that silica gel must be spread in burlap sleeve filled with some soft material within the glass panes. Their eyes just roll over to the back of their heads. I see a bunch of DIY spending thousands to do a project which will result in a slightly better attenuation than gluing egg cartons on the wall
M, I had to laugh to myself about your comment. I go through this sort of thing everyday. People don't understand how much is required to achieve noise, music, and voice objectives. I try to educate using simple examples but companies have done a good job of misleading and misrepresenting the truth when it comes to isolation and treatment requirements. Its an uphill battle every day. Jump in anytime and assist. You are more than welcome here.
Well said man, you made my day. Some people can’t handle facts.
Is that intended that the sound of this video (unlike your others) has such a low quality to show the issues you are talking about? :-) There is some 50/60Hz bass hum which needs treatment :-) Now seriously: Pointing out the floor and ceiling reflection issue is important: Many people overlook this for some reason. Hard to believe, but even 2 out of 3 companies, asking me to check their room reverb emulation software did not take them into acount propperly. :D. Thinking into the 3rd dimension seems to be an issue for many people. Also rear reflection is sometimes earlier than the side in wide but short rooms when the listener sits at the back in the "HIFI" position.
Hi Juergen, In the beginning of our video endeavors, I was and still am still focused on content and not delivery. We were growing quickly and moving around a lot. I used whatever I had available that was quick to set up and use. I have over time improved upon that system and our new series even uses a black board instead of a white. Lighting a blackboard is much easier without the reflections of a white board. Comments range from only about the audio presentation and no comments on the content to those such as yours that mix both together and then those that are just content driven. I delete the first group without hesitation, because they contribute nothing to the real discussion.
Rear wall issues are always a concern along with, as you point out, the side walls in narrower rooms. Another issue that is overlooked in the treatment of both of these surfaces is the proper rate and level of absorption to match and compliment the chosen usage. I don't know where this one size fits all approach got started. Not calculating the proper reflection time signature for both side and rear walls using the correct rate and level, is a common error and see and hear even with older studios in LA.
I guess it's all about cleat definition. Stating that 100Hz is not a low frequency is all fine as long as you are clear about the consequences of such a statement.
Concluding a bass trap won't be able to absorp bass is just as misleading as all the pirates out there stating you can control all of your low frequencies with their bass traps. 😂
First of all: to my knowledge there is a clear distinction between bass and sub bass, the first being around 60-250Hz and the second one being from 20-60Hz. Having the illusion that your can control 60-250Hz with some 100mm bass traps is ofcourse utopic.
Still, by setting clear goals and respecting the audio on most certainly get a hold of more than this guy is stating. By departing from a good triangle (speakers in relation to the listening position) in relation to the room and the right placement of bass traps you can surely get enough control in high, mid, lower mid range and bass to get a good result. Lower bass and sub bass not so much.
The separation of 100Hz up and 100Hz down is in my opinion a real fact. You need a complete different technology to be able to control that range.
Still understand his way of putting things if you are also selling products and competing in a market full of pirates. 😂
I can only be responsible for what our products perform at. The acoustic world is full of ignorance and outright nonsense. Classifying low frequency energy as energy below 100 hz., separates the energy and the treatment methodologies for better understanding and application. Energy below 100 hz.,regardless of frequency, requires a pressure based technology, while energy above 100 hz. can be achieved with molecular velocity methodologies.
@@AcousticFields That really makes sense. So in other words: everything aboce 100Hz can be absorbed by velocity absorbers. Following the 25% rule you would theoretically at least need 33" of insulation material with a low density and flow resistivity to absorp that energy?
Why not just say which dimensions are bad, mid and good? For talking so much, so little info was given! Guess this video is just saying, contact us for info . .
laphtoabeat Thanks for the comment. In future videos we do give starting guidelines but we can't give everything away or our competitors would take the 8 years of R&D we did building, measuring and testing rooms of all shapes and sizes to compile our database. I'm sure you can appreciate that.
That said, in our latest videos we are providing more step by step guides as I think we've covered a lot of the over all theory elements and now its time to get down to the nitty gritty.
Thanks
Dennis
laphtoabeat the point of marketing is to give away the "what" for free. However if you want to know the "how", you gotta pay for it 😉 nothing wrong with that at all. How do you expect Dennis to run a company if he's giving everything away to the freeloaders?
I guess it would be completely futile / useless for a 'poor staving artist' - to watch this ... !?!! Peace / LOVE
Unshackled Spirit Not at all. Knowledge and wisdom are the tools to progress. Peace and love to you.
Cheers
Dennis
Thank you Dennis Acoustic Fields ... You're absolutely right & I have watched a bunch of your videos . Peace / LOVE !!
This knowledge is NEVER useless. Musicians have a tendency to ignore the most basic of acoustics. Even if you can not dump $300 on simple treatments the KNOWLEDGE is invaluable. If you are a drummer and just LEARN how to build and tune a GOBO .. you are miles ahead of 90% of drummers out there.
Seldom so much free info on such profitable industry has been given on TH-cam or any other media for FREE . Knowing just a few basics in drum mics you can turn a gig around and YOUR value will increase exponentially.
This is a video of acoustic, but I can't understand anything :v
S, What question do you have? Please be specific.
Does ANYONE trying to build a private recording room understand the 3 to 1 rule ?
Don't Laugh AF!
M, We find the 3 : 1 rule to be a good start point. Final speaker/listening position is always an end result of tuning the room over time.
30hz to 50hz doesnt matter at all, focus on 100hz to 500hz instead
Hi Cameron, 100 - 500 cycles is vocal and those precious mid ranges. However, 30, 40, and 50 cab be just as good if managed correctly. Come to my studio in LA for a demo. It will change your life.
tnx for video ! still it's kind of funny that you talk about good sound and your videos have the worst sound ever :) sorryyyyyy for mean comment :)
Hi J2Sf, opinions on the sound quality of our videos fall into two categories. There are those that realize that the message, with its many years of experience and knowledge behind it, for its benefits to their particular room situation. The messenger or delivery system becomes a non issue. As long as it is not distorting speech intelligibility, message prevails. That has always been and will continue to be, my primary objective. Acoustics is physics based and the physical sciences are not the strong suit of many of my customers. Trying to take this physical science act and put into a framework that people can understand that have no physics background is difficult. I try to take the "what will it sound like in the room" approach and say to people,"did you ever hear this or that". They usually say, yes, about hearing the room distortion, but don't know what it is called. Once they know the name, they then understand more and I can better assist them. It is this level of understanding I seek with my customers. The more you understand in small room acoustics, the more enjoyment you get out of your room and gear. And with as much time as we all spend in our rooms, don't we all deserve less room and more music. I know I do.
I was expecting more examples, pictures, videos, comparisons etc. Not very useful.
Expectations are a wonderful thing. In business, you must always weigh cost/benefit for any marketing consideration. We have increased our production value on all 2021 videos. Watch our new videos beginning. 2/21
For a video talking about proper room acoustics, the audio is terrible! Seriously? You didn't make a small effort to improve the audio by applying your own principles for this video? I appreciate the contents, but it's difficult to take you seriously when you're put off by the audio and struggling to understand the commentator.
N, Do you have anything to say regarding the content that would assist our audience?
my motto is - have no room at all. dont want any 'liveness' anywhere. dead dead dead. we try to only attack problem guys because of time/money etc etc. but i would much rather mix in an anechoic chamber or in the middle of the grand canyon. but i cant, so i try my best to fix what i got. but i make no promises about my skills at doing so
