How to Make High Performance Sound Absorption Panels for $5

  • Опубликовано: 8 авг 2016
  • In this video I explore the possibility of making DIY sound absorption panels on a budget, later comparing them to much more expensive acoustic foam. The results are pretty amazing!
    There have been many comments pointing out that my test only measures transmission and not reflection, so is essentially unsuitable for my initial testing goal. While this is partly true, testing reflection is pretty difficult to do in a home environment, and the only way to do it that I can think of would be to spend a long time in the middle of a field with a powerful speaker and mic rig, which is really beyond the scope of what I was prepared to do for the video.
    My tests are not rendered pointless however - it would do no good to have only measured reflection, as the thinnest lightest material would have won (like foam), as nothing would have bounced back. Reflection and transmission need to be tested together to measure how much sound passes through, and how much sound is reflected back - this should give an indication of how much sound is absorbed by a given material.
    Regardless, only testing the transmission doesn't affect the outcome of the project at all, as any sound waves reflected by the panels themselves would have theoretically bounced off the wall anyway - again this is why reflection wasn't tested, as it doesn't matter so much for a panel setup (though would matter very much for a vocal booth).
    Open to hear any thoughts about it though! Keep up the great discussion. :)

    Brilliant! Why is everything better when a pleasant Englishman presents it. For those who didn't recognize it, Matt was using an ironing board as a platform to lay his towel on. Very British, indeed! Did you see his garden? In America we refer to that as our backyard. A "backyard" in Cockney is a reference to a women with a rather wide bum!

    I'm thinking about adding an acoustic liner to the partition wall when I move house to avoid having issues with my neighbour when I fire up the home cinema system, but you have reminded me that I also need to consider my own acoustic environment.I doubt that towels will be involved but I may find a use for some "Wood Fibre Underlay Boards".

    Dumb test. You would (wrongly) get better result if you put a flat piece of wood in between the speaker and and the mic, hell put a piece of metal if you want, and that says how stupid this test is. You're doing sound blocking test, and not sound reflection test. Room acoustic treatment is about improving sound reflection, and not about blocking sound.

    I was doubting the sound absorption untill you actually spoke with the panels in the room. I was thinking that the towels were just blocking the noise, creating similar results on the test.

    Does this dampen sound or absorb it? I've been reading a lot of comments questioning the actual affect this has on acoustics, to me the comparison at the end is more than enough. But can you elaborate on the difference this panel has on sound absorption vs dampening?

    Dude out of all the acoustic videos I've seen your's was by far the best. It's like the foam boys are trying to make a sale of cheap foam calling it "acoustic" foam. Having said all that, I have done this a ways back. However, with my DIY project, a friend and turn his useless old barn style garage into a major cinema using several piles of pallets behind a warehouse, landscape shade house netting, and loose fibrous house insulation matting. However, getting back to your solution, having done this before, I got a slightly better performance when I offset my panels from the wall by an 1.5". Here's why: some of the sound wants to hit the panels at an angle and it can't. So by allowing for some room behind the panels, sound gets trapped back there. However, 1.5" was all I got, anymore and the DB meter went up. Any less and the same. I couldn't tell the difference blindly but the meter didn't lie...

    Thank you for this vid. I am woundering what the quality of sound would be like if you were to put a couple of hinges on a couple of the panels, so as to essentially have folding, portable absorption panels, and erect them directly behind your microphone. Is that something you might consider and share in a future video?

    Great video which started a quest for the best material for sound treatment for my space.
    I have arrived at recycled Denim which has a sound absorption coefficient of 0.95 (allegedly 95% of the sound is absorbed ) and acoustic fading of 42 dB with a density of 45 kg/m3 (+/-10%). The stuff comes in plates of 45 mm x 80 cm x 90 cm and sells for about EUR 9.36 per m2.
    It's steep compared to Rockwool (Rocksono Solid 211) which has an alleged sound absorption coefficient of 0.70. The latter comes in plates of 45 mm x 100 cm x 60 cm and sells for EUR 4.77.
    What speaks for Rockwool is: it's proven technology. The Denim materials is allegedly hard to handle in terms of cutting it to size. Some RUcliprs have used power tools with success but from the looks of it, a DIY support tool allowing you to temporarily compress the material and simultaneously guide a sawing blade through it should do the trick.
    That said, it's a tough call in terms of effectiveness and economics. Hope this contributes.

    You get better result by just taking 20-40mm mineral insulation wool sheet. Spraying it with spray glue and placing some thin sporous canvas on top of it. Like the canvas they use for making speaker covers. And glue stiff paper sheet on the other (back) side of the wool. The glue, canvas and the paper/cardboard will hold it's shape and you do not need wood frames for it.

    Actually, the panel performance is much better than the measurements you show would predict. The panels hanging on the wall work in reflection, i.e. a double pass configuration. The measurements made are in a single pass transmission configuration. In reflection you have twice the towel thickness. Nice video. liked it !

  • Oscar Burke

    Interesting video, however the testing you did was invalid as to the "acoustic value" of each type of surface. What you did do is test and demonstrate the value of "soundproofing" or in your words "sound absorption" here is why. What you are trying to achieve is a acoustically "dead" room ..An example a empty room four bare walls ceiling and bare floor is a "live" room as you know when you are in such a room it sounds like a tin can. And you already know you put a rug on the floor and you reduce this "tin can" effect add more items and you further reduce it To demonstrate and see this you can put your speaker in the room and microphone connected to an oscilloscope looking at the tone from the tone generator and the tone on the microphone you will see a single wave form from the tone generator and multiple waveforms from the mike. This is caused by the reflection from the hard smooth even surfaces of the floor walls and ceiling. Now add the rug and you will see this reduced or attenuated. So to achieve a "dead" room of the desired level you need to prevent that "echo" or "reverberation" you need to add uneven or non reflective surfaces to the room. Acoustic foams are not "sound absorbent" but are non-reflective. The reason you saw the results you saw is because the foam was doing exactly what it was designed to do. You were not testing the reflectivity but the sound absorption. Since acoustic foam is not dense the air passes straight through it and the sound wave is broken up so as not to be reflected but is recreated has the air moves through the foam and the sound wave is reproduced on the other side but attenuated somewhat. This is also why to achieve maximum effectiveness of the acoustic foam it must be installed flush against the walls and any other surfaces you need. If you were to use a high density foam it would fail to give results because it is too dense. The reason "egg crate" foam is used is because the shape also prevents the reflection of low frequencies. The reason your "towel" works is simply because of the coarseness of the towels surface. I would be willing to bet that one thick or maybe not even thick in a frame place against the wall would achieve the same effect all you really did with multiple towels wash increase the soundproofing ability which is pointless unless you do it to the entire wall, at least for preventing the sound from being heard on the other side of the wall. But my compliments on a great looking result and it works as you intended just not exactly why you think it did.

    Has anyone tested this method using canvas for paintings? Not only with the canvas as it is, but layering towels behind it. It could be an easier alternative for someone who can't find the wooden frame alone. I'm thinking about trying it.

  • MrCunan
    MrCunan 28 дней назад

    You showed how much sound your materials block, not how much they absorb. nonetheless those towels are definately a improvement. if you want a broadband absorbtion till 100Hz or so, you need stuff wich would not pass your specific test at all. like sonorock (quite cheap). two important factors in absorbing (low) sound with porous absorbers is the thickness and reflection. quite expensive stuff like basotect does not do much better if it is thicker than 10cm, because lower frequencies will just be reflected back (into your room). You could improve your absorbtion if the sound is not reflected partially in the absorber, but at the wall behind the absorber. so it will travel a second time through the absorber on the way back, thus absorb also lower frequencies that passed the first run and thus be more even in absorbtion. Such an absorber wont be good at your test but in reality it will absorb more. Most difficult thing with absorbtion is a even absorbtion of all frequencies and not just the highs. If you just want to kill early reflections and some high frequencies, towles work fine. I write this, because once I treated a room for drum recordings in a similar matter. and it was not succesfull because all the high frequencies where gone and the low frequencies where still boomy. actually it was quite uncomfortable to be in this room, because there was no reflection from voice - felt like a coffin. i guess, if you just record voice in your room or stuff like that, all that does not matter so much and those DIY absorbers are just fine.

    Amazing video.. One question tho. If you don't want to make your own frame, could you just as easily go to like a Goodwill store and find a couple very large canvas piece and then layer the back of it with towels stiched together and stapled to the back of the wood like you suggest. My take on that is that while the towel in front is softer than the rougher fabric that comes without whatever canvas photo that it would still work well with towels packed inside of it--and maybe hung up look better too?

  • André Jordaan
    André Jordaan 29 дней назад

    @DIY Perks Your tutorial is really well hosted, however, your tests are incorrect. When measuring the RT60 (Reverb Time at 60dB) you need to measure reverb, not sound absorption. Your panels will work extremely well with keeping sound out, but does it really work any better than the foam when it comes to reverberation within rooms? Not sure if you have a video that covers this, but would really appreciate a video looking at this. Keep up the good work. :)

    In olden times we did cheap acoustical control with things like blankets, foam, sofas and coats ("Salad days"). But one better idea is office cubicle panels. In Flor-duh... there are so many places that go out of biz & just trash them. As in 'free'. We have dozens. Cut and re-frame them and put them on wheels. They really suck the sound in and are as good as way overpriced Aurelex which falls apart anyway. Don't forget to do the overhead to dull out the 'bounce'. Now go make some cool stuff!

    You should make a follow up in which you Pink a small room with these panels to show people how to use them properly. Also do a test of like maybe a drum kit in a room and use that real foam vs your towels to see what actual musical noise gets absorbed and whether it sounds better or not.

    I would like to see what happens with carpet and/or padding. Used carpet (or unused cutoffs) is frequently available free. Beware odors.
    When assembling frame corners, if you've already put glue in the joint it may help to clamp before drilling to prevent sawdust and wood chips getting between the boards. I like to drill one hole, apply glue, put in the first screw to hold the joint together, then drill the other screw holes. This ensures that the holes line up.
