How to Make High Performance Sound Absorption Panels for $5

  • Опубликовано:  Год назад
  • 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. :)

      A wood panel in front of all those towels would reflect the sound back into the room...just like the wall does. You'd essentially just be building a mini wall and hanging it on the wall. Leaving the towels exposed is the whole key to absorption of the sound that would have hit the wall and/or reflected back off.

    pretty cool although you did do something wrong. you did your test with a flat piece of acoustic foam and a flat piece of foam isn't going to absorb much if anything it will reflect, the foam needs to have notches in it. the notches are what absorb the sound because when the sound goes in between the notches it kind of just bounces around in between the notches until it dies out. that's why anechoic chambers have those big triangular blocks protruding from the walls, it traps the sound in between the notches so there is no echo.

    Why is it that an excellent video such as this attracts so many aggressive know-alls, for whom a little knowledge is a dangerous thing?  No, the test is not conclusive, but it is simple and practical and goes a long way to evidencing the effectiveness of the cotton towels. The sound that doesn't pass through is either being absorbed or reflected. It is obvious that a pile of towels reflects comparatively small amounts of energy; the rest is absorbed down to a surprisingly low frequency. For really low frequencies of course mass absorption is needed - diaphragmatic, Helmholz, membrane, etc -  but these panels don't pretend to be offering that solution.

    Hi Matt: You are totally lovely! I appreciate your input but my issue is the TRAIN noise which in the USA is covered by Federal Guidelines so they don't have to respect their neighbors. I am only 500 feet away from a switching station and needless to say what with my backyard neighbor cutting down 5 trees (had no choice I understand; Asian Beetles) and across the street from my sleeping space in the front of my home built a 20 foot graduated cement garden and I am now bombarded by the reverberation when the trains start can last all night- up to 16 hours at a time which is affecting my health after 7 years....Can you confirm please if this option will work for windows in a wooden home covered in slack (poor) stucco and an open cement basement? I rent and it's not inexpensive to live here in Minneapolis so I don't want to move....Any kind assistance/suggestions would be Most Appreciated!!! I will be out of pocket for this upgrade....rental company just wants their rent. Thank You for any suggestions you can possibly provide!!!

    Although towels are great for this purpose and probably are the best material that you tested, I do not agree with your test method. You tested the amount of sound that passes through the material, but the test should be of how much sound reflects off the material, since the purpose of the panels is to reduce reflections. A material that reflects 100% sound would allow 0% to pass through. That would seem like the best material based on your test, but it would in actuality be the worst.

    Hi! I am amazed at the towels performance! Long live the towel, then! I have one question for you. I came across your video while looking for an effective (possibly also cheap) way to make my Yamaha U3 upright piano sound a little less intrusive for neighbours. Now my question to you is, provided I do use you idea of sound absorbing panels behind the piano itself, will they help, you think, absorbing much sound in general? (I could maybe muffle the inside between the strings and the hammers also with felt) Thanks very much in advance and sorry for the lengthy comment.

    These tests confuse sound conditioning with sound proofing. Your opening statement about reducing room echo says you're looking for sound conditioning. But your tests are testing sound proofing.

    An example: a 5-inch thick layer of ceramic would absorb a lot of sound and do well in your tests. But it would be horrible to line a studio with.

    And a fuzzy blanket would do poorly in your tests, but would be much better to line a studio with than lining it with a 5-inch thick layer of ceramic.

    Ok, I really hope people read my comment, and take precautions. I'm not saying you CAN'T use this method, just be mindful of the risks and take steps to minimize them.

    1) Fire hazard. These can be hung on walls, but do *NOT* put them in a spot where there are outlets that are going to be used. Keep all electrical wiring away. Keep any and all sources of heat away, don't put them over heating vents or radiators, and obviously, no open flame.

    2) Moisture. If your studio or office or youtube-video-making-hole-in-the-wall is not humidity-controlled, well, it should be, for the sake of all the equipment. This could be as easy as getting a meter and finding out that it just happens to stay at around 30-38% ambient humidity all the time, so you don't NEED to get any additional equipment. It *COULD* be more complicated, if the humidity gets high, you need a dehumidifier (you can obviously turn it off while you're recording) in that room. High humidity in a room with a bunch of towels hanging on the walls can be a huge problem, leading to the growth of mildew and mold, even deadly black mold spores that will go airborne the moment you turn on a fan or do anything that shakes the towel-panels around a bit.

    There IS a better option, but you can't quite do it for 5 bucks a panel. Do exactly what he did with the wood frame, but then put in some rigid fiberglass insulation (Owens-Corning 707 or 705 or 703, or Roxul if you have a bit more to spend). The white towel on the outside is an acceptable covering, although in won't be necessary, and you could cover it cheaper with basically any dense fabric (ask about the fabric's resistance to fire and moisture) from the fabric store. You obviously need to cover BOTH front and back of these panels, so you aren't getting dust from the insulation in the air. Use hot glue around the edges to make a decent seal, and if you are using speaker-cloth or a similar stretchy nylon or rayon type fabric, maybe wrap two layers to contain the insulation well. This will raise the price of your acoustic treatment to around 20 bucks a panel (4' x 2' panels), but it will also do a far better job inhibiting the reverberation and comb-filtering of the really low frequencies, which are the ones that are most problematic for recording audio, and also LISTENING to audio, if you are editing, mixing, mastering a musical track for your video, or if you came to this video because music is what you do and why you need acoustic treatment in the first place.

    Good luck everyone. Feel free to ask me any questions, if you don't get an answer within a day, it means I didn't get a notification, so just post it on my channel.

    I think your test has a fundamental flaw. Your sound absorbent material is placed between your mic and the speaker, so your test is effected by the density of the material. Therefore a sheet of glass would give a better result than the other absorbent materials you tested. Your test is set up for measuring sound passing through a material but what you really need to test is what happens when sound bounces off the material. Then you would find that the sculpted foam performs much better than a dense sheet of smooth glass. It would have thought that this error would be an obvious one.

  • Punk Duck
    Punk Duck Месяц назад

    What you measured is sound transmission not absorption. As it is towels are absorbing sound giving you a good result in the room, at least at vocal frequencies. However if youd placed concrete slab in the test rig (balanced on super strong string!), youd probably get a good result, but this would be because of reflection rather more. I applaud your inventiveness in any case. I wonder if other fabric would work as well, say curtain material. Id hazard a guess that its the layering of the material that increases absorbance. Good work anyway!

    I think this guy is just elegant when it comes to making videos and it's a rare quality not found in many hosts these days. Cheers mate.
    Also, for a youtuber or content creator who just got a 250$ condensor or a Zoom H5 for his/her vocals echo is certainly a main concern and only people who listen/track/record 24bit audio in a studio environment will ever have to face the challenge of getting that perfect deflection to absorption ratio that makes their recordings wide and crisp. You wouldn't need to fret that much if you weren't such a professional. On the other hand if you just wanted to soundproof your room then this might not be the solution for you. You would be better off layering chipboard and foam an inch or so away from your walls and reinforcing the doors so thwy don't leak, or.... you could always just find a better place to jam :p just sayin... I personally just open up my cupboard where all my clothes are and play my acoustic facing the cupboard so the sound doesn't escape off the room walls and it doesn't so there's another idea for guitar players.

    So you are picking/testing most sound blocking material, not most sound absorbing. If i.e. some material will reflect 100% of speaker sound mic will not pick that up, but this material will be the worst for room-treatment. For the real test you should put speaker and mic on THE SAME side of tested material.
