How to Make High Performance Sound Absorption Panels for $5


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. :)

Shame this was entirely the wrong measurement. A slab of concrete would have performed better than all of them, but been entirely useless at reducing echoes. The correct measurement would have measured the sound reflected from the material, not what passed through it. That would be equally easy to set up.

This treat mid high to high frequencys. The hard part to get rid of is low frequency and low mid... When you treat them, generally the midhigh and high are under control. Often, they are too much lowered and the room sound dead. We put a thin layer on top of acoustic treatement to give a bit of life back to the room and boost the low frequency's capacity of the treatment. I would say that this is a good solution if you are planning to record violin or voice. For speach, intelligibility is arround 3khz so it would be good also. Early reflection is the number 1 thing to take care of at the beggining. For those who are interrested, see Ethan Winner or Winer webpage (i don't remember correctly is name) anyway, he give a lot of advice and he know is stuff... For you, good try, but you should have read a bit more on acoustic to talk about the limitation and application of your device.

David ClickDavid Click (7 дней назад)
This test was totally done wrong lol... The sine wave test is testing how sound proof the towel is, not how absorbent it is. In order to test how much its reflecting/absorbing, he would need a mic on the side of the speaker emulator. This is stupid unless you're trying to build

I was wondering could you overlay posters over them. I have several spots in my room where I would like to place these towel frames, but at those spots there are some posters. I was wondering if I could just put the posters over them. Would they still work? Would the sound just bounce off the paper? I really enjoyed your video by the way please do make more content!

Suggestion....Don't include the tones in the audio from your tone generator. I am listening to this with ear buds at a moderately low level and those tones are ear-piercing! When you did the first live test I turned up the volume to hear the difference between the bare walls and the paneled walls. Then you tested the professional acoustic tiles ....I ripped the phones out of me ears! AAAAARRRRGH! Jeez!

Jeff ZakanyJeff Zakany (9 дней назад)
It's just the frequency of the tone itself. High frequencies hurt my ears. But I did turn it up slightly to hear the difference in the treated and untreated walls.

You are testing sound insulation not absorption. So you have no good idea of the reflected, diffracted and absorbed sound. You'd be better off doing this in a room and in reality your acoustic panels off then on the wall test is more telling of the effectiveness than the "test" outside. But interesting video.

Michael TaylorMichael Taylor (15 дней назад)
You didn't test sound absorption you tested sound blocking they are two completely different things, and there a 3 things that decide how well an acoustic material (usually foam) is, Sound Blocking (makes where outside sounds do not get through it) Sound Diversion / Deflection (how well the material makes the sound bounce off in lots of different directions) and sound absorption (how much sound is actually absorbed into the material)

Michael TaylorMichael Taylor (15 дней назад)
You did have the right idea with your panels though, they work and do a good job for the price (although they are not "better" than actual acoustic foams that appear on the market, just diffrent

Did you find the best type of towels. And why towels and not layers of the same cloth, like cotton. Is it about the weave? Is it better to use 1 very thick one or several thinner ones adding up to the same thickness?

Mark EdwardsMark Edwards (21 день назад)
I thought of this a day after my last comment. Just because the sound isn't passing through to the other side doesn't mean it was absorbed. Think about using a 1/2" (12mm) plate of steel. Probably very little sound would be picked up by the mic. But most would be reflected. We need a different test method.
Thanks again for posting.

There is a huge difference between sound blocking and sound absorbing. You could put a piece of plywood on there and It would probably fare well in this test but it doesn't absorb much sound. In a studio you want to absorb sound with your baffles to reduce certain frequencies not block them. I don't think this test tells you much but I appreciate the effort.

Fredric GeorgssonFredric Georgsson (1 месяц назад)
The mic test does not consider reflection? A slab of concrete or stone would win the test easily, but not absorb anything at all? I think the best bang for the buck is usually found in insulation materials such as glass wool?

the acustic foam does not absorb the sound. It is designed to work with the reflected sound waves. you should try the whole process with not absorption but reflection - set an accusticaly neutral wall in 45 degree angle and measure the reflections from it with the different matterials. the towel solution works but I have a feeling it dampens the sound too much. in deaf rooms there are absolutely no eco and it can drive some people crazy. the purpose of the acustic foam is not to absorb the frequencies but to lighten the overll interferencies and small noises, as eco is still needed :)

I wonder how well denim insulation would work compared to the towels

Panos LaPanos La (1 месяц назад)
well that's just wrong... usually acoustics are difficult to handle at frequencies up to 500hz... another thing is that you actually measuring the soundproofing ability of your acoustic panel rather than the absorption which is necessary (when sound is hit on a material one part of the energy is absorbed by the material, one is reflected and one gets through it). and finally some other things you have to consider is hygiene... towels can be a cosy place for moisture and thus fungus... also you don't want to have something on your wall which potentially can be a fire Hazzard... so... good idea but I wouldn't recommend it
