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. :)

    What material deflects sound without vibrating, such as acoustics? I want
    to deflect it back my direction so I know to use a parabolic curve or
    circle with the material.

    Sry but you tested the egg foam wrong. The bumps should ALWAYS be facing the source of the sound. You did it flat side facing the speaker.

    You need to test that again.

    I want to block trafic noise, dogs, esp low frequency from two windows. Is towels, rockwook, butyl , automotive products going to be best. Cheap prefered but cost not critical.
    Thermal insulation would also be a plus.
    How close to the glass window should I mount the frame?
    Im also putting in a plasterboard wall. Whats best in the wall for noise and thermal insulation.

    Another good test would have been putting the mic behind the speaker and/or between the speaker and the materials with the materials in front of the speaker to test how much sound reflects off the surface of the material, which is probably the most important bit of info.

    fyi "acoustic foam is snake oil. It's a terrible material for absorption. you'll find real 'traps' use high density fibreglass (rockwool) combined with a lead loaded vinyl membrane)

  • kumoyuki

    the testing methodology is *hugely* flawed, especially when it comes to the A/B comparison of acoustic foam. All you are really doing here is converting a "live" small room into a rather less "live" room, and for simple vocal recording that is enough to produce important changes in the perception of the recording. You'd easily get the same results with any strategically placed acoustic mass (e.g. squishy armchair/sofa/carpets). And geometry matters, hence my comment about "strategically placed".

  • Elliander Eldridge
    Elliander Eldridge 14 дней назад

    so if I wanted a soundproof fence, I guess the cheapest solution would be to line the inside with towels, put wood on both sides of them, and tap it with some kind of waterproofing material so that the towels don't get wet? I should try that sometime. Boom cars are really annoying.

    I'm going to make those panels you described in this video specifically to go inside of a fence and see how it helps.

    I wonder what the insulation value of this would be for the inside wall of a shed that you wants to be soundproofed completely, compared to other types of insulation, or maybe in combination with them.

    All this proves is towels are better than absorbing than "re-labelled packaging foam" how would they compare to the proper acoustic panels is what I'd want to know!

    He could have compared the weakest absorption material to a box of grapes and came to the same conclusion!

    • Phil Golden
      Phil Golden 12 дней назад

      There is cheap and there is efficient. Not for the sake of content but for the sake of education! If towels compare well with proper acoustic panels I believe the 'results would be pretty amazing'. If you could compare $5 panels to how good they are against expensive ones then it would be worth spending $5 on panels on a budget instead of just guessing that they are good. Just because they are towels and you can get them for cheap it does not mean that they will work the same when it's not even a proven method of acoustic treatment. If they compared well I would go out and buy the towels!

    Google User 25 дней назад

    Regardless of whether it absorbs or blocks sound I just want the noise from outside as well as from upstairs where a noisy roommate lives to be stopped so I can sleep and study in peace. Tried ear plugs but after few hours my ears swell and hurt. I know it absorbs sound but does that mean if you hang it over most of the wall that the noise coming from outside won't be heard? Basically that's my goal. Also does it stop low frequency sounds like car doors slamming, roommate upstairs banging and stomping hard where it shakes the downstairs, and buses going by that cause rumbling which shakes the rooms? I'm looking for cheap method as I'm pretty poor.

    • Korishan
      Korishan 22 дня назад

      Yes, covering your walls in cloth will dramatically reduce sounds coming at you (whether from outside the room, or within). You could even hang carpet remnants, large body/beach towels, or any other type of cloth material. Obviously the more layers, the more reduction.

      hobbyist audiophile, and eliminate sound deflection is redundant, sound dampening would be proper, the word eliminate isn't needed there because you're not eliminating anything

      this is why bose gets so much crap from sound guys, because the system they use to produce sound is minimalist at best, although lately, I believe they have some more traditional ways of producing sound. Bose uses two, sometimes paper speakers in pairs faced at each other and send the sound through tubes before it reaches the air outside, the waves hit each other and many of the wavelengths cancel out each other getting rid of the noise, Bose cannot produce medium range tones as no cheap speaker does well, because it is the low tones that carry the most weight and stay with us the longest. the beat is carried in the lowest tones and the harmony and melody are carried in the medium and highest tones.

    • Kevin Queen
      Kevin Queen 4 дня назад

      through the use of traps, see the sound waves are just compression of the molecules in the air, different compression rates produce different sounds, once the compression gets below or above a certain rate we cannot hear it, so we deflect the air molecules enough to dampen the sound below a certain compression rate. if you've ever been in an audiophile room then you will notice that the walls have planks sticking out of them, no surface is smooth and the ceiling is usually hanging with a space around the edge. and there is one sweet spot in the entire room to sit in. some ppl will spend $70,000 or more on one of these rooms. I, however, did not.

      You can do any kind of cloth arrangement. Remember, he said you could get patterned ones so you could have a piece of art on the wall, too. Get a body/beach towel that has a huge tiger, or flowers, or cars, or whatever on it and use it for the primary display.

      I was thinking this too. However, I was thinking of putting the inside towels on first and stapling them only on the backside, then put the front one on stapling over the back ones. I think he sewed them together to help keep the several internal layers in place. Put you could possibly fix this by putting this strips of wood inside and stapling to that with short staples. My thoughts, anyways.

    You can also add a sheet of fiberglass to give a nice dense layer on the back side and maybe a middle layer. Fiberglass is great for blocking sound due to its density and can be found or made pretty cheaply.

    Not quite sure about that. I am no acoustic expert by all means, but dosent the towel simply reflect more sound than the foam? Sure it absorbs some sound but compared to foam/rockwool panles i bet they reflect a lot more and thats the reason for your results. I think your Test setup isnt thought out correct.

    • derChili
      derChili 16 дней назад

      Korishan I said the towel absorbs some sound. But way less than foam. It reflects more than the foam. Think about it. He needed a second measuring mic that measures the reflected sound. Than you would notice that the towel don't absorbs more sound then the foam it just refects more than the foam back to the speaker. The efficiency of absorbing sound is not correct measured in the video.

    • Korishan
      Korishan 20 дней назад

      I still don't see how the towel isn't absorbing sound. It's obviously reflecting far less sound than without, so his tests proved successful. He was looking for a way to limit the echo and reverberation, and he did exactly that. Not only did he accomplish that, but his voice is now clearer and more distinct than it was before (because of the lack of overlapping sound waves). So his experiment was a success. Not a failure. You state that you are not an expert of acoustics. Looking up sound absorption on youtube will give you loads of information on the subject. That is what I did before posting my results. There are several acoustic companies that posted information related to absorption and reverberation and echo, and they all fall in line with what he did with this experiment.

    • derChili
      derChili 20 дней назад

      Korishan Shure the Towell is absorbing some sound but the foam is absorbing more. the towel has a better result at the test because it reflects more than the foam but absorbs less sound than the foam. yes the room sounds better with towel panels than without. His test is wrong. He needed a mic that measures the reflected sound and one that measures the absorbed sound.

    • Korishan
      Korishan 22 дня назад

      At the testing where he talking in the room with and without the panels up, you can clearly hear his voice is more pronounced and clear when the panels are up. The towels are absorbing sound energy, not reflecting them. It's because the towels are fibrous material. All those little fingers move to the sound and absorb and dissipate the energy through motion. If you looked really close, you'd probably see the cloth move to the sound (especially if you had a loud bass beating)

      It wasn't all about what is all around "better". It was about what was easy to make, relatively inexpensive, and did a fairly good job. Of course he could of gone with high grade, professional sound proofing panels. But he said he was looking for an inexpensive way to accomplish a similar result. It's not perfect, but it's a whole lot better than without the panels.
