This is incorrect. The foam panels are hybrid panels which both deaden and diffuse the sound. The plastic diffuser only diffuses the sound. Diffusion makes the echo more "even", more neutral and pleasant. But for a recording scenario it is better to have the room dead, and only foam can do that. The thicker the foam, the better it performs in deadening resonant bass problems as well.
Other materials like rockwool and heavy cloth can dampen as well. You can even make absorbers out reflective materials like wood depending on the shape of it. For example, if you get a hollow wooden box with a hole in it, any sound that enters the hole will get stuck reflecting inside the box, meaning it absorbs the sound.
@@Zadamanim they are not bad to have for room acoustics, carpets also do a great deal. but nothing compares to the efficiency of acoustic foam. the wooden box you are describing is a resonance absorber. it needs to be foam lined on the inside to work and unlike a large foam pad it only absorbs a specific (low) frequency range. again, not as good as plain old panels but it's used to target problematic room modes (resonance) when everything else is already okay.
okay so my question is, if you would make a mould out of one of the panel. and made it thicker then mould it out of some foam would the effect be simmilar or even better?
@@mikload the pyramids and other contours on foam panels are largely cosmetic. they do add a small amount of diffusion but plain flat foam panels are actually the most efficient absorbers, just with a very unappealing look. The problem is that the efficiency of the foam depends a LOT on the material. Cheap general purpose foam will work but special foam engineered for maximum acoustic absorption will outperform it by a huge margin, needing less area for the same amount of deadening. Finally, the thickness of the foam panels determines the bass response. Thin panels will only absorb the mid and high frequencies. For voice recording purposes, you are usually not concerned with the bass response since the voice contains very little of it and it just gets filtered out in post.
Not necessarily. Those foam panels do next to nothing. But, then again, this panel is flat with no angles, so it will just reflect the sounds back the way they arrived. Edit for clarification, since people are missing the point. The $10 Amazon foam panels do next to nothing for absorption, because they are not dense. They absorb almost no sound. Likewise, the 3D printed wall panel is not only not dense enough, it is also not shaped properly for diffusion and is not going to provide any sort of absorption. Diffusion panels are useful, only when used in combination with absorption. Absorption panels must be dense and thick, like 4" Rockwool insulation.

Given the structure size and depth of only a few cm, this panel will only diffuse frequencies around 5-10 kHz. Lower frequency waves (human voice) will still see a hard plane wall. The structure size has to be between around 10 and 100 cm. I guess the foam will still do a slightly better job.

Also 3d printing allows all types of geometric intricacies. The internal ingil could be arranged in alternating materials of varying densities and with an internal structure representing an inverted conch shell or a fractal geometric composition. I mean honestly it doesnt take too much imagination... frankly I'm shocked that you havent figured out ways it could be possible and are on the side of the accepted, stunted progress of yesterday rather than the innovation of tomorrow......
Deadening a room is so you can have try to have a flat frequency response, and give you control over how you want things to sound. I don’t know much about 3d printing, but it seems to have many applications, just know diffuse is to keep the sound from bouncing all over the place and giving weird noise or feedback, and absorption is to kill any reverb and to make things stop right after the sound, example: clap your hands in a bathroom, notice the echo and reverb and the acoustics of the room, then clap your hands in a “dead room” and the sound should dissipate instantly. Hope this helps a little, I remember a little bit of stuff from audio engineering school 20+ years ago😅
96th like and no comments, lemme fix that! 💯% agreed! I my studio I used a wall filled with books which provide a similar effect. Alternatively a cheap and reliable way would be to cover a wall with pool noodles which are perfectly shaped for diffusion and thick enough for absorption.
As an audio major I can assure you that this is flawed logic. Those definitely serve a purpose, but they're not a replacement for the sound absorbing foam panels. All they do is stop standing waves and nasty resonances.
Even these are of limited function. Density, wall thickness, material, and X,Y dimension play a factor. They do not look dense, and are not deep at all. I’d be surprised if these help at anything lower than 5-6khz
Cheaper and easier and more effective is…. TOWELS. I swear by this, tested it. Buy a bunch of towels from the thrift store, hang them on the walls, or place them in old picture frames, about 8 towels thick, and it ABSORBS the sound, not just diffusing it. Helpful in my suburban garage setup. Foam doesn’t decrease volume at all.
wait buddy, i record in my room in a low budget setup, so this can really help me a ton. You mean 8 layers of towels or 8 towels throughout the room? Lol
@@nooneiszzm I just made panels out of old picture frames, 8 towels deep; some hung on the walls, some on the ceiling, some just as moveable boards for wherever I need for a particular application. Drops the dBs like crazy. I tested the volumes with multiple materials, and towels worked the best. (There are videos of how to do this, how I found out about it). You also end up with a SUPER DEAD room; no reverb at all, so you can do all that in post-production with an incredibly dry clean signal to work with. Hope this helps.
@@Luclin a few layers of carpet goes a long way too. That is also in my set up. The reflective concrete block walls also needed treatment. I tried rugs on the walls, but upon testing against the towels, the towels were way more effective. Super quiet and almost no reverb whatsoever, so you get a super dry clean signal to work with in post-production. Also the neighbors don’t complain
I agree this is very effective and wanted to add that stage curtains are an example of how well this works. Not only do they block the sound coming from the stage to the audience , but when good stage curtains are closed you might think you were about to perform to an empty building and yet curtains open to a packed audience. The sound travels through the air, so after a 2nd layer of curtain you will have created an air gap in the middle where the air doesn't want to move because its trapped between two curtains.
spider roomba is the solution. spider roomba, spider roomba, does whatever a spider can. although if you got andrew garfield as spider man he'd surely clean them while he's already up there
Cheaper to by the foam panels then to print these ones. Probably running close to $3 a panel. It all depends on the price of the filament and the infill percent (Which I am guessing is less then 10). Regardless, these look pretty cool, though I was wondering if there are caps to hide the screw holes.
Cheaper _and_ they actually work. I’m not sure what scam the video maker is running here but please for the love of god just buy foamboard. It is literally made for this. Hard plastic is not.
I don't think these pannels will be very effective for noise cancelling. They don't absorb (only reflect), and such a small height difference (circa 1 cm) will not cancell or significantly diffuse the longer sound waves ( ~35 cm for 1KHz). Besides, not a very cheap and time-consuming solution. Why not buying standard specially designed pannels or DYI similar ones?
Aside from your confusion regarding sound diffusion and absorption, these things actually have to be calculated for each individual room according to your results with the measurement microphone.
Hey man, let me save you a lot of money and time, and tell you that plastic will not dampen sound like that foam does. It bounces the waves all over. It doesn't lower the bounce-back at all, it just makes it sound more open and you get less of a "singing in the bathroom" effect.
"most favorite" is a redundancy expression. if it's the most liked it's implied it's your favorite. if it's your favorite, it's implied it's your most liked.
@@GBOB68 it’s true that sound damping is affected by a lot of factors like density, porosity, and even surface texture, but if we were to hold those constant and only increase the elasticity of a material, there’s a good chance it will absorb more energy and therefore be more effective at dampening sound. it still does depend on various other factors like the resonance of the material and hell, it might mostly transmit certain frequencies. so what i stated was that, all things held constant, a more elastic material will likely absorb more energy, but i couldn’t be certain if the damping effect would be perceptible in this application. i’d like to know what’s wrong with my assumptions.
@@SHKEVE The tile is a sound diffuser. It relies on the sound waves being reflected from all the different surfaces rather than being absorbed into them. I don't have the time to fully explain but that's a summary of how the tiles work. Hope this helps.
@@GBOB68 i understand how sound diffusers work - i was only entertaining the question of whether building diffusers out of different materials would have an impact on sound dampening to which i stated that it likely will. when elastic materials are deformed (e.g. when hit by sound waves) they will convert some of the acoustic energy into heat via internal friction. i also wondered if this would be noticeable to our ears or if it would be like asking if wearing a raincoat will give some protection from standing next to a thermonuclear blast. yes, it technically will provide some protection but you’d be vaporized all the same.
Although the idea is good, these wont do much on their own due to the material. Foam absorbs the sound, plastic just bounces it around. You could combine these tho, would work nicely.
@@TGMisKillingTheMiddleClassIt’s 3D printing filament. It is solid. That’s how they work. Even if the inside is hollow the material is solid. It bounces sound, it doesn’t absorb it like a porous soft foam does. It’s just physics. That’s _why_ wall sound dampeners are foam and not hard plastic.
it diffuses reverberation And the acoustic foam pads with the diffusers would make a better work than just filling the wall with the diffusers. Add a good absorbant curtain and carpet and you could have a less reverberant room, but it may also may make your room less welcoming acoustically speaking... Still, filling it up with the diffusers may break the purpose of having them
Diffusion and Absorption are very different. Also, 3D prints aren't anything close to "Professional". The material matters and you literally showed us a clip of the print, showing a very thin walled hollow structure.
@@deathtiki my recommendation is that if you are trying to reduce echos, use acoustic foam. Or if you're cheap. Stacked towels work just about as well. Diffusers are used to make echos and reverb equal across a wider range of frequencies. The material for this should be hard and dense. Something that sounds bounce off. Wood is great. Or you could print shells, and fill them with concrete or plaster. That'd be wonderful, but expensive and super heavy.
You know how I know this won’t work? Because caves have so much echo even when they’re not smooth. Also to describe something as producing a large amount of echo, you can call it “echoey”.
Each one probably costs around $5-10, including electricity used. Right? Depending on the filament used, at least. Hella cool, will never be as good as triangles, though.
Looks like $1:30USD to me and my supplier. It isn’t structural so basically hollow. Probably wouldn’t work with much of a range though. It needs to be deeper or add the foam back to it.
This is not going to work well. But watch out for people suggesting using packing foam or matterss toppers. Both are flammable as hell. Google the nightclub fire and read about The Station. The best choice is probably rockwool safe 'n sound. Just make a 1x4 frame and cover it with whatever kind of fabric you want.
@@ruisuter6139fiber glass would be terrible but yeah you can print, sand, make a silicone mold and start producing insulation foam versions but they might make the room a little hot and the startup process is way longer. Still though it is a great idea to do it fast but if you have a fast printer then the process is a lot more automatic and hassle free and doesn't take that much longer... Either or will work
"Professional Grade" and 3D home printing don't go together lol. Maybe buy professional grade sound diffusers rather than some shitting ass packing foam
Stop acting like you know something and need to tell us. Also that foam is cheap af. The prints aren't professional grade. I'm using Basotect for better acoustics
"my goal is to fill the entire wall" Ouch... Don't do that. Don't just go ahead and slap a bunch of diffusers on your wall. Look up how to do acoustic treatment correctly, please
You made this the least fun way possible! We used 2×2 lumber, cut it random sizes and pieced it all together. Ok, maybe a bit more expensive, but way more fun, and actually more effective at the job.
@@Cycronos Imma shamelessly nerd out here. Diffusors break up sound into "smaller" or just different segments, making echo, reverberations and reflections less strong. However, if you want them to work properly in a setting where accurate audio is necessary, you need a fairly large area for the sound to have the space to gradually break up and you would likely need some more absorbing material. If you want to have less noise coming from outside, you can try putting some absorbing material on the wall where the noise is coming from, best if it was on the side of the source if there was a wall between you and the source, but you can try perhaps setting some thicker material a bit away from the wall on your side with an air collumn in between and that could dampen some sound. Any doors, windows, vents and other gaps will let sound through most. If you provide some padding there, there will be a big difference in volume. Well... I hope this helps a bit and I hope you find a way to reduce noise.
So u dont pay anything for electricity? I live in The Netherlands and last time I checked the electricity was at least as, if not more, expensive as fillament
Those are not a diffuser bud, it has to be a material that can reflect and absorb sound, like WOOD. PLASTIC ONLY REFLECTS. I'm a college trained music engineer and I specialize in studio design, room attenuation and recording. While what you printed will help remove standing frequency if place where they accumulate, it is not and can not diffuse sound waves. Sorry..
@@gamingsnake1769 It takes minutes to cut them randomly frm some scrap wood and the you simply glue them on a board. It would be cheaper and faster. 3D Printing is cool and all but some things simply don´t make sense to print. Or would probably take me longer to open a CAD program slice the part and so on than just cut them pieces.
Hmmm. Lets see. Cost of filament and cost of electricity to operate the equipment. I see so many 3D printer people not mentioning their GODLY electric bill.
😊 3D printing is not energy intensive, if indeed your KWH is that high no one would be able to afford to run a clothes dryer or an A/C unit. In those conditions Printing would be the least of your worries. Average $25 per roll for plastic, maybe 5-7, depending on lighting infill, my guess with electrical included $3/per panel. With maintenance and labor $5per panel, and a couple hours R&D and modeling and screws… my guess is $6per panel assuming there are at least 30panels to average out the non-printed costs. 👍
$3 a panel for eletricity? Where do you buy the eletricity from? Lol. These types of 3d printers have 100-125 Wh power consumption so running it 10 hours consumes 1-1,25 kWh which costs 23 cents in average in the USA according to the internet.
@@hologos_ no that is I plastic+electric for $3 per panel... I was adding in the rest because progressively, because ‘cost’ is a relative term. To be more precise $2.90 in plastic and at most $.10 in electric for a nice round $3.
I mean for what it’s worth and I’m sure someone mentioned this but this is not professional grade simply bc of the material. More importantly, diffusion may have a pseudo “randomness” but proper diffusion is done by complex maths and is made for a specific room . I’ve made these after being in the space. Measuring, and running software to work out the angles and an algorithm to ensure smooth scattering. It’s an important point bc ppl have diluted what a diffuser is. And I could be wrong but that board just looks like different heights not custom made for that room. A blend of sound “treatment” is required combining deadening and diffusion on all surfaces to move sound around the room like a game of audio tetris. For instance if you do spread the waves, now what? No foam dispersed to catch it. Also the benefit of knowing your spread even if random. To catch the waves jn predictable spots. Again that’s why those types of “diffusers” with THAT many blocks would’ve useful. I personally much prefer to move sound intentionally around where I want it then deaden depending on the room
With a bit of forethought, you could end up with something a lot more appealing than a black wall. Although I guess you could paint it afterwards as well.

Interesting comments. Indeed, diffusion and absorption are different, needed for different frequencies. Also, my comments are from a 2 channel listening application, not a recording application. The video shows a decent concept for diffusion IF the cell size is correct for the target frequencies. Room testing will show exactly what frequencies are giving you trouble, so you can design the panel accordingly. Also, diffusion is generally less effective in small rooms and near field listening. However, the 3D printed diffusor is a sound idea (no pun intended) so long as the shape/size of the "block" is correct and small groups of panels are placed strategically. Covering an entire wall can actually degrade the listening experience... time and amplitude are a calculated part of sound quality in a given space, and deadening a room completely can hurt both listening and recording experience, depending on what you are listening to, or recording. Most music recording studios are only dressed where needed so that the mics can be optimized for a desired sound. I think the neat idea regarding 3D printed items is that manufacturing is no longer a hinderance. If a smart person can design the specific shape/size (and combinations of shapes/sizes used) on a diffusor panel, they no longer have to figure out how to accomplish making that unique panel. I also think a 3D printed diffusor panel could be effective with slots or holes in certain surfaces (the panel being printed as a hollow shell) and the hollows on the back of the shell filled with bits of rockwool or some other proven absorption material. This way you get the best of both worlds, and much cheaper than commercially available products available from companies like GIK. Everyone here is a freaking genius. The FACT is that there are literally unlimited ways to dress a space when trying to achieve a desired sound. Especially if you get creative. Example... I once had some thick ass floor mats from a 2004 Nissan Maxima, back when they were still making quality products. Heavy but supple rubber clad with really thick automotive carpet. The shit was designed to absorb road noise, and it was cheap way to deaden the sound in the car. I was getting a spike when room testing, so for a goof, I hung it next to one monitor about a foot away, between the monitor and the side wall with the carpet facing the monitor. Spike flattened immediately. SQ improved immediately. It wasn't practical or aesthetically pleasing, but it worked way better than dressing the wall. Moral of the story... don't shit on someone for trying new things. Innovation is born of a need to accomplish a goal. Just report the results so we can all benefit from your trials.
So - as mentioned elsewhere he'd need 42 panels. 42 x $130 (Ender 2 Pro), and 42 x $3.50 for panel materials - whole wall printing = 3.5hr @ $5607 (excl. hospital fees for PLA poisoning!) :)
Wow, a lot of people who know better in these comments. Perhaps one of you can chime in on a related topic. My buddy was building this type of diffuser using wood blocks. I offered to develop it a bit further since I have a CNC mill, and added that we have more freedom regarding geometry, for example using generative patterns. My buddy refused this, saying it HAS to be the square configuration of blocks, that it has been calculated for optimal results. My argument is that the specific geometry is due to conforming to an available material (wood beams) and given the right constraints another base geometry could perform just as well, if not better. What do the know-ot -alls here have for input?
I looked this up, unless you have a very fast printer, each panel would take near a day. Plus, even without any infill, its gonna be 200-350gr each panel. PLA is around $15-20 per KG. So, no.
Tedious and somewhat laborious, expensive, time consuming, plentiful options that work better and cheaper, dust will be an ass, and it wont even work anywhere near like u think it will.Quite literally the most IMPRACTICAL thing ever
guy with audio engineering diploma here. Those foam panesl look to me as though they are extremely lightweight. I'm pretty sure they are acoustically transparent, even though they are sold as being acoustically absorbent. I've done experiments to test this kind of thing out, so i know what to look for.
Why would you do the whole wall? Most sound gurus recon something like 15 and 20 % absorption / diffusion. I'm no expert. But seems the room might start to feel odd acoustic wise
"Proffessional grade"? Yeah, i don't think so. that's not going to be effective. Maybe on a small wavelength, but it's going to be very limited. There is a reason that professional sound dampening panels are much thicker
To anyone interested 3.5 hours and about $3.50 per panel to print, $150 for the whole wall (found him saying it in another Shorts video with the panel in the thumbnail) So that's going to take 150 hours to print

No thanks,!
Given the structure size and depth of only a few cm, this panel will only diffuse frequencies around 5-10 kHz. Lower frequency waves (human voice) will still see a hard plane wall. The structure size has to be between around 10 and 100 cm.
I guess the foam will still do a slightly better job.
You havent factored internal structure or density of plastic, not mentioning material composition and type
I'm eager to see the replies from "professional sound engineers" like the person above me. (And yes the OP is correct, the panel printed is doing mostly nothing)
@@fzigunov obviously a panel that small would have to be made of some rather fantastic and probably at this point, theoretical materials at the size printed and given commonly expected means afforded by the individual who printed it. The idea is that at scale or with newer more dynamic 3d printed materials (which admittedly may be out of the means of the video posters parameters) the ignorance and suredness with which both of you speak about something which has so many variables is frankly obnoxious and not conducive to the epwrimwntal nature of science and discovery, especially in this modern age in which so many previously held beliefs are being adjusted or disproven. Even just going by your video of jetstream acoustic manifestations due to resonance from the induced loop, while not entirely original is in the spirit of experimentation.

@@samueletienne9158 can you explain, how an object with a normal mode in the range of several kHz (typical for small thin-walled objects made out of PLA, PETG, ASA, or ABS) can dampen frequencies which are about one order of magnitude lower?
@@craesh i think you answered your own question....it would have to be out of the normal mode. As i said earlier it would have to be experimental materials(maybe even theoretical and not one of the four that you listed. Ideas off the top of my head- if the material that this is comprised of is printed larger and out of a ballistic gel type of material or a foaming material that created copious micropores. Also 3d printing allows all types of geometric intricacies. The internal ingil could be arranged in alternating materials of varying densities and with an internal structure representing an inverted conch shell or a fractal geometric composition. I mean honestly it doesnt take too much imagination... frankly I'm shocked that you havent figured out ways it could be possible and are on the side of the accepted, stunted progress of yesterday rather than the innovation of tomorrow......
Deadening a room is so you can have try to have a flat frequency response, and give you control over how you want things to sound. I don’t know much about 3d printing, but it seems to have many applications, just know diffuse is to keep the sound from bouncing all over the place and giving weird noise or feedback, and absorption is to kill any reverb and to make things stop right after the sound, example: clap your hands in a bathroom, notice the echo and reverb and the acoustics of the room, then clap your hands in a “dead room” and the sound should dissipate instantly.
Hope this helps a little, I remember a little bit of stuff from audio engineering school 20+ years ago😅
96th like and no comments, lemme fix that!
💯% agreed! I my studio I used a wall filled with books which provide a similar effect. Alternatively a cheap and reliable way would be to cover a wall with pool noodles which are perfectly shaped for diffusion and thick enough for absorption.
As an audio major I can assure you that this is flawed logic. Those definitely serve a purpose, but they're not a replacement for the sound absorbing foam panels. All they do is stop standing waves and nasty resonances.
He's part of the lower bell curve of the general population😂😂
wrong......that is not ALL they do.....they ALSO....look cool ;)
Even these are of limited function. Density, wall thickness, material, and X,Y dimension play a factor. They do not look dense, and are not deep at all. I’d be surprised if these help at anything lower than 5-6khz
I love the part where he tells us how much they cost.
Cheaper and easier and more effective is…. TOWELS. I swear by this, tested it. Buy a bunch of towels from the thrift store, hang them on the walls, or place them in old picture frames, about 8 towels thick, and it ABSORBS the sound, not just diffusing it. Helpful in my suburban garage setup. Foam doesn’t decrease volume at all.
wait buddy, i record in my room in a low budget setup, so this can really help me a ton. You mean 8 layers of towels or 8 towels throughout the room? Lol
Actually thick carpet under pads are cheaper and more effective.
@@nooneiszzm I just made panels out of old picture frames, 8 towels deep; some hung on the walls, some on the ceiling, some just as moveable boards for wherever I need for a particular application. Drops the dBs like crazy. I tested the volumes with multiple materials, and towels worked the best. (There are videos of how to do this, how I found out about it). You also end up with a SUPER DEAD room; no reverb at all, so you can do all that in post-production with an incredibly dry clean signal to work with. Hope this helps.
@@Luclin a few layers of carpet goes a long way too. That is also in my set up. The reflective concrete block walls also needed treatment. I tried rugs on the walls, but upon testing against the towels, the towels were way more effective. Super quiet and almost no reverb whatsoever, so you get a super dry clean signal to work with in post-production. Also the neighbors don’t complain
I agree this is very effective and wanted to add that stage curtains are an example of how well this works. Not only do they block the sound coming from the stage to the audience , but when good stage curtains are closed you might think you were about to perform to an empty building and yet curtains open to a packed audience. The sound travels through the air, so after a 2nd layer of curtain you will have created an air gap in the middle where the air doesn't want to move because its trapped between two curtains.
When you go from "cheesy" (professional) panels to "professional grade" (cheesy) panels😂😂

Cheaper to by the foam panels then to print these ones. Probably running close to $3 a panel. It all depends on the price of the filament and the infill percent (Which I am guessing is less then 10).
Regardless, these look pretty cool, though I was wondering if there are caps to hide the screw holes.
Cheaper _and_ they actually work. I’m not sure what scam the video maker is running here but please for the love of god just buy foamboard. It is literally made for this. Hard plastic is not.
I don't think these pannels will be very effective for noise cancelling. They don't absorb (only reflect), and such a small height difference (circa 1 cm) will not cancell or significantly diffuse the longer sound waves ( ~35 cm for 1KHz). Besides, not a very cheap and time-consuming solution. Why not buying standard specially designed pannels or DYI similar ones?
“It doesn’t align but it feels really precise”
ok
The plan is to cover the entire room with plastic
I appreciate the fire- and smoke-resistive properties of my gypsum board walls too much to cover them with a toxic smoke source
Aside from your confusion regarding sound diffusion and absorption, these things actually have to be calculated for each individual room according to your results with the measurement microphone.
Technically yeah, but in my experience anything is better than two parallel flat walls.
@@andybrice2711That… wasn’t the point here. It’s not meant to be better than empty walls, it’s meant to be better than regular foam. Which it isn’t.

Hey man, let me save you a lot of money and time, and tell you that plastic will not dampen sound like that foam does.
It bounces the waves all over. It doesn't lower the bounce-back at all, it just makes it sound more open and you get less of a "singing in the bathroom" effect.
"practical"
Spent dozens of hours and tons of filament to print a fancy panel that doesn't work anywhere near as well as cheap egg crate foam

I wonder if printing in a flexible filament like tpu or even foaming pla would increase the sound dampening
it will definitely increase damping, but if it's noticeable or worth the cost is another thing.
@@SHKEVEWrong. I'm not going to explain, but if you're gonna give an answer you should attempt to only answer things you actually understand.
@@GBOB68 it’s true that sound damping is affected by a lot of factors like density, porosity, and even surface texture, but if we were to hold those constant and only increase the elasticity of a material, there’s a good chance it will absorb more energy and therefore be more effective at dampening sound. it still does depend on various other factors like the resonance of the material and hell, it might mostly transmit certain frequencies.
so what i stated was that, all things held constant, a more elastic material will likely absorb more energy, but i couldn’t be certain if the damping effect would be perceptible in this application.
i’d like to know what’s wrong with my assumptions.
@@SHKEVE The tile is a sound diffuser. It relies on the sound waves being reflected from all the different surfaces rather than being absorbed into them.
I don't have the time to fully explain but that's a summary of how the tiles work.
Hope this helps.
@@GBOB68 i understand how sound diffusers work - i was only entertaining the question of whether building diffusers out of different materials would have an impact on sound dampening to which i stated that it likely will. when elastic materials are deformed (e.g. when hit by sound waves) they will convert some of the acoustic energy into heat via internal friction.
i also wondered if this would be noticeable to our ears or if it would be like asking if wearing a raincoat will give some protection from standing next to a thermonuclear blast. yes, it technically will provide some protection but you’d be vaporized all the same.
Audio engineering “might be one of my most favorite” things. However, we should just leave the poor guy alone - he can’t even speak correctly!
Although the idea is good, these wont do much on their own due to the material. Foam absorbs the sound, plastic just bounces it around. You could combine these tho, would work nicely.
doesnt that depend on the internal structure? you are assuming these are solid
@@TGMisKillingTheMiddleClassIt’s 3D printing filament. It is solid. That’s how they work. Even if the inside is hollow the material is solid. It bounces sound, it doesn’t absorb it like a porous soft foam does. It’s just physics. That’s _why_ wall sound dampeners are foam and not hard plastic.
it diffuses reverberation
And the acoustic foam pads with the diffusers would make a better work than just filling the wall with the diffusers.
Add a good absorbant curtain and carpet and you could have a less reverberant room, but it may also may make your room less welcoming acoustically speaking...
Still, filling it up with the diffusers may break the purpose of having them
Acoustic foam has high density porous angled surfaces. This is now how acoustics works
I really hate that you did the cheezy "guess how much they cost to print. Come-on man
Diffusion and Absorption are very different. Also, 3D prints aren't anything close to "Professional". The material matters and you literally showed us a clip of the print, showing a very thin walled hollow structure.
Would rubber applied to the back help with that?
@@deathtiki my recommendation is that if you are trying to reduce echos, use acoustic foam. Or if you're cheap. Stacked towels work just about as well. Diffusers are used to make echos and reverb equal across a wider range of frequencies. The material for this should be hard and dense. Something that sounds bounce off. Wood is great. Or you could print shells, and fill them with concrete or plaster. That'd be wonderful, but expensive and super heavy.
You know how I know this won’t work?
Because caves have so much echo even when they’re not smooth. Also to describe something as producing a large amount of echo, you can call it “echoey”.
practically, those foam pads are practical
Each one probably costs around $5-10, including electricity used. Right? Depending on the filament used, at least. Hella cool, will never be as good as triangles, though.
Looks like $1:30USD to me and my supplier. It isn’t structural so basically hollow.
Probably wouldn’t work with much of a range though. It needs to be deeper or add the foam back to it.
This is not going to work well. But watch out for people suggesting using packing foam or matterss toppers. Both are flammable as hell. Google the nightclub fire and read about The Station. The best choice is probably rockwool safe 'n sound. Just make a 1x4 frame and cover it with whatever kind of fabric you want.

only eco
echo
@@j-bob_oreo Ah, what a shame....
Anywho, thanks for the replies guys!🙂
@@Cycronos Imma shamelessly nerd out here. Diffusors break up sound into "smaller" or just different segments, making echo, reverberations and reflections less strong. However, if you want them to work properly in a setting where accurate audio is necessary, you need a fairly large area for the sound to have the space to gradually break up and you would likely need some more absorbing material. If you want to have less noise coming from outside, you can try putting some absorbing material on the wall where the noise is coming from, best if it was on the side of the source if there was a wall between you and the source, but you can try perhaps setting some thicker material a bit away from the wall on your side with an air collumn in between and that could dampen some sound. Any doors, windows, vents and other gaps will let sound through most. If you provide some padding there, there will be a big difference in volume. Well... I hope this helps a bit and I hope you find a way to reduce noise.

Hmmm. Lets see. Cost of filament and cost of electricity to operate the equipment. I see so many 3D printer people not mentioning their GODLY electric bill.
😊 3D printing is not energy intensive, if indeed your KWH is that high no one would be able to afford to run a clothes dryer or an A/C unit. In those conditions Printing would be the least of your worries.
Average $25 per roll for plastic, maybe 5-7, depending on lighting infill, my guess with electrical included $3/per panel. With maintenance and labor $5per panel, and a couple hours R&D and modeling and screws… my guess is $6per panel assuming there are at least 30panels to average out the non-printed costs. 👍
$3 a panel for eletricity? Where do you buy the eletricity from? Lol. These types of 3d printers have 100-125 Wh power consumption so running it 10 hours consumes 1-1,25 kWh which costs 23 cents in average in the USA according to the internet.

"Professional grade" a straight up lie
I mean for what it’s worth and I’m sure someone mentioned this but this is not professional grade simply bc of the material. More importantly, diffusion may have a pseudo “randomness” but proper diffusion is done by complex maths and is made for a specific room . I’ve made these after being in the space. Measuring, and running software to work out the angles and an algorithm to ensure smooth scattering. It’s an important point bc ppl have diluted what a diffuser is. And I could be wrong but that board just looks like different heights not custom made for that room. A blend of sound “treatment” is required combining deadening and diffusion on all surfaces to move sound around the room like a game of audio tetris. For instance if you do spread the waves, now what? No foam dispersed to catch it. Also the benefit of knowing your spread even if random. To catch the waves jn predictable spots. Again that’s why those types of “diffusers” with THAT many blocks would’ve useful. I personally much prefer to move sound intentionally around where I want it then deaden depending on the room
I wonder if you can get some foam insulation panels with 2 different thicknesses and cube them up an glue them on thin plywood an paint.
:D So maybe will diffuse the sound wave but it will resonate at probably 200hz - 300hz . Let us know in a different video :D
With a bit of forethought, you could end up with something a lot more appealing than a black wall. Although I guess you could paint it afterwards as well.

Interesting comments. Indeed, diffusion and absorption are different, needed for different frequencies. Also, my comments are from a 2 channel listening application, not a recording application. The video shows a decent concept for diffusion IF the cell size is correct for the target frequencies. Room testing will show exactly what frequencies are giving you trouble, so you can design the panel accordingly. Also, diffusion is generally less effective in small rooms and near field listening. However, the 3D printed diffusor is a sound idea (no pun intended) so long as the shape/size of the "block" is correct and small groups of panels are placed strategically. Covering an entire wall can actually degrade the listening experience... time and amplitude are a calculated part of sound quality in a given space, and deadening a room completely can hurt both listening and recording experience, depending on what you are listening to, or recording. Most music recording studios are only dressed where needed so that the mics can be optimized for a desired sound.
I think the neat idea regarding 3D printed items is that manufacturing is no longer a hinderance. If a smart person can design the specific shape/size (and combinations of shapes/sizes used) on a diffusor panel, they no longer have to figure out how to accomplish making that unique panel. I also think a 3D printed diffusor panel could be effective with slots or holes in certain surfaces (the panel being printed as a hollow shell) and the hollows on the back of the shell filled with bits of rockwool or some other proven absorption material. This way you get the best of both worlds, and much cheaper than commercially available products available from companies like GIK.
Everyone here is a freaking genius. The FACT is that there are literally unlimited ways to dress a space when trying to achieve a desired sound. Especially if you get creative. Example... I once had some thick ass floor mats from a 2004 Nissan Maxima, back when they were still making quality products. Heavy but supple rubber clad with really thick automotive carpet. The shit was designed to absorb road noise, and it was cheap way to deaden the sound in the car. I was getting a spike when room testing, so for a goof, I hung it next to one monitor about a foot away, between the monitor and the side wall with the carpet facing the monitor. Spike flattened immediately. SQ improved immediately. It wasn't practical or aesthetically pleasing, but it worked way better than dressing the wall. Moral of the story... don't shit on someone for trying new things. Innovation is born of a need to accomplish a goal. Just report the results so we can all benefit from your trials.
They might be at different heights, but they're on the same plane and made of hard plastic. Barely any different than a bare wall.
Most favorite... 🤢🤮
So - as mentioned elsewhere he'd need 42 panels. 42 x $130 (Ender 2 Pro), and 42 x $3.50 for panel materials - whole wall printing = 3.5hr @ $5607 (excl. hospital fees for PLA poisoning!) :)
Wow, a lot of people who know better in these comments. Perhaps one of you can chime in on a related topic. My buddy was building this type of diffuser using wood blocks. I offered to develop it a bit further since I have a CNC mill, and added that we have more freedom regarding geometry, for example using generative patterns. My buddy refused this, saying it HAS to be the square configuration of blocks, that it has been calculated for optimal results. My argument is that the specific geometry is due to conforming to an available material (wood beams) and given the right constraints another base geometry could perform just as well, if not better. What do the know-ot -alls here have for input?
I looked this up, unless you have a very fast printer, each panel would take near a day. Plus, even without any infill, its gonna be 200-350gr each panel. PLA is around $15-20 per KG. So, no.
Tedious and somewhat laborious, expensive, time consuming, plentiful options that work better and cheaper, dust will be an ass, and it wont even work anywhere near like u think it will.Quite literally the most IMPRACTICAL thing ever
diffusing ≠ dampening
Unless it is printed from TPU, it will do nothing. PLA is rigid and will just diffuse sound above 4-5 khz. Itcs good for singing, bad for voice.

Shoulda blue tacked them on instead. But I’m just a perfectionist. You might not care all that much😂😂
guy with audio engineering diploma here. Those foam panesl look to me as though they are extremely lightweight. I'm pretty sure they are acoustically transparent, even though they are sold as being acoustically absorbent. I've done experiments to test this kind of thing out, so i know what to look for.
Why would you do the whole wall?
Most sound gurus recon something like 15 and 20 % absorption / diffusion.
I'm no expert. But seems the room might start to feel odd acoustic wise
"Proffessional grade"? Yeah, i don't think so. that's not going to be effective. Maybe on a small wavelength, but it's going to be very limited. There is a reason that professional sound dampening panels are much thicker
