How to Make High Performance Sound Absorption Panels for $5

  • Added:  11 months ago
  • 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. :)

    The towels Just bounce the soundwave's back, wich is the problem in the first place.

    Great research. Nice job for absorption. If you want to take it one step closer to recording studio environment "diffusion" is also required in concert with absorption. Shop bought diffusion panels can be really expensive. Any ideas ?

    We collected catalogs of carpet samples (stores are happy to give away old ones free!) and stapled the carpet tiles all over the walls, door, and ceiling of our 'music room'. Easy to apply 2 or more layers with tacks or nails.
    We never bothered color coordinating so it looked awful, but it worked brilliantly!!!! ;)

  • Mike G

    Nice test and to everyone saying this test is wrong and implying that the towel reflected the sound away instead of abosrbing it, his before after test in the room completely debunked your statments, If the towel was just reflecting the sound, there wouldnt be such a noticable difference when he put the panels up so clearly the sound is being ABSORBED. And LOL at ppl bringing up concret slabs and plywood.. a towel is no where near those so just because those will do good on this test by not letting sound through and reflecting it doesnt mean thats what the towel is doing. it just seems like towels are veryy good at damping sound. Id like to see how it does down to 100hz.

    THANK YOU FOR THIS GREAT IDEA! I don't have the tools or skills to make a wooden frame but your video inspired me to find an alternative. My wife is a painter and has many stretched canvasses on wooden frames around the house that aren't being used. I was able to pirate one and modify it suitably using foam, towels and an old fleece blanket, all got from op shops (like Salvation Army) for almost nothing. I was also able to get more canvasses that had been donated to Salvos. Although the pictures on the canvas were frequently hideous, they were given purpose by me re-creating them as sound absorption panels. Again, thank you.

    I wish DIY Perks Put the material informaion such as measurements, types of wood, sizes of towels.
    1. if i were to build this, what measure ments would i need for each piece?
    2. what would the measurements be if i didnt put a miter cut into it.
    3. about what size wood, would you start out with. for example 2 by 3 by 8. is an example of a measurement of wood. out of that what would be ideal about using?

    I want to build the measurements similar to the video but the information isn't all there :) if you could add those into the description or comment on my comment I would be greatly appreciated!

    My plan is to film my build and seeing how my build matches up with yours :D ( i have no experience with building with wood)

  • Ed Witte

    I noticed from the video of your testing of the acoustic foam - there's something protruding from the microphone and touching the foam. This could cause a direct conduit for the sound waves and could adversely affect the results.

    Making ten of these to form a folding screen so that the noise from our A/C is diffused when we record. Does anyone know what would be a method that's just as effective as sewing? After sewing two of the panels, it's getting very tedious after cutting the material.

  • EumlOriginal
    EumlOriginal 20 days ago

    Unfortunately, your method is not suitable with the test for the desired result ...

    Which you have tested is not how much sound is absorbed, but what is less sound-permeable

    But the sound should come through the material in order to remove the energy, but if the resistance of the material is too high the sound will be thrown back

    Acoustic cotton - made from recycled denim - is sold commercially as a sound absorption/sound proofing product. There are several companies which make products ranging from insulation batts for walls to small squares for spot treatments and everything in between. And it is indeed one of the most efficient sound absorbing materials.

    Why measure the sound they let trough if you are only interested in what they don't reflect, (try putting a thick panel of glass in between, it Wil come first out of the test, hang your walls with glass and you have a reverb-room)

    why do you use such high frequencies? Human voice mainly takes place in the range below 4khz. and transmission properties are often different to reflection properties.

    Am I wrong, or does his test not actually test the echo reduction? The foam isn't supposed to stop sound from passing through it, its supposed to stop sound from bouncing off of it.

    you need various density material in-between to spread the over the frequency range. also, the frame may not touch the walls... it would create a sound bridge...

    In your tests you are confusing sound absorption with sound insulation. You are checking how much sound is being prevented from passing through the material, not bounce off of it. Towels perform better in your test because that have greater mass (which is the main factor in getting good sound insulation). However, sound absorption depends more on porosity and other factors. Notice, that in your test a wooden or concrete plank would perform best! That is why sound absorption tests are performed in reverberant chambers, not in free field, i.e. garden.

    Flawed test, but the idea is still good though. I do believe that "acoustic" foams are mostly rubbish. Simple mineral wool works much better, but the towels are a great idea as well! However, I am pretty sure that you need to spend more than $5 to get 4-5 towels and all that timber framing...

    the towel doesn't "absorb" the sound as much as it will not let it though in this case, making it more of a diffuser basically... try the initial test with a sheet of metal for example and I dare you to say it absorbs sound ;)

    Lots of missinformation!!!
    There is a difference between sound absorbtion and soundproofing. (Google it!!) the setup in the video measures the soundproofing because the microphone is on the other side of the material. But what affects the sound “quality” inside the room is the absorbtion. To keep it simple: flat surface = more reflections= bad sound. Like a wall for example. This is why the towel thing works.

    this is a test of sound BLOCKING not absorption!. To properly test for sound absorption, you need to create an echo chamber, by putting the speaker and microphone in a wooden or metal box together with the material lining the walls, and measure the echo.

    The acoustic foam isn't meant to absorb sound like how you tested it's meant to limit echos and the towels just muffle the sound they do help with echo cancellation but you didn't test the foams correctly
