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. :)

    Beware don’t use damp towels! Even just slightly damp towels can either catch fire or become mould havens.
    Dry them completely and spray them with furniture protector before use. You can also use silicone sealer to glue the towels to the frame and a blob or two to glue them to each other.
    You don’t need a frame either just hang them over a curtain rail. Don’t pack them tightly it’s the gap between layers that does half the job.

    Cool! I will probe rely be looking into sound proofing for a small studio apartment- use case so I can watch movies / listen to music / play games without bugging the neighbors! Not sure how this would scale up though. Also the low frequencies are the toughest ones.
    I used to put foam behind cardboard movie stands that I used to get working at a video store. I used them to cut down on 1st and 2nd order reflections in my bedroom/home theatre room. They did a great job and looked great too!

  • andocrates

    Great experiment. However anyone who is actualy reading this because you need sound panels.
    The goal of acoustic foam is NOT to act as a sound barrier, that is done with vapor barriers and 8 inches of fiberglass insulation in the walls. You don't want the room to be dead, like singing in a closet. You just don;t want early reflections. Still you found what you needed and did it, that's good.

    that reminds me of my experience with the Bundeswehr / German army
    3 felt duvets hung with 1 meter spacing each are bulletproof against 7.62 NATO ammunition
    if they are wet even against ammunition up to 23mm from the russians. you have to think about it ,
    7.62 NATO comes through 60 cm wet / living wood.
    a reason why I always laugh when in a movie the hero gets behind 10 cm plywood safely without getting hit.
    P.S. By the way, in my old days, you had to be once on the receiveing end in the shooting practice to learn how it sounds
    so no wonder, towels are the best choice ;))))))))

      i think if the painting was glossy oil it would reflect a tiny amount so not that good, but it was printed or watercolour then the sound would pass thru and then in the towles, I like the idea, and I think ill have a go.

    Hello, i was wondering about the effectiveness with polystyrene though as that was not part of the test?
    I am busy completing my venue and the current acoustic problem is rather bad with a bad echo and no ceilings - my building is in the style of industrial warehouse therefor i do not want drapes or ceilings and all steel frames are exposed. After many other snags and costly mistakes people made i am definitely looking at the toweling options however would like to know of polystyrene would also do the job.

    This vid is well done but ideas are amateur (but yes cotton is good). Absorbing and blocking are not the same thing btw. Polyester batting is probably the best for all considerations...since cotton gets a bit funky after a few years..if you've left cotton clothing in closet with rewashing for a couple years...kinda like that/stronger after several years. Noticeably, but not horrible. I know this from using recycled denim batting for several years. But, it is best performer and is easy/friendly to work with. You can make nice panels by using 2'x4' 'luan' the thin wood covering for interior doors, is easy to find. Is about 1/8 thick or so. Anyway, just take 2" batting, either denim or polyester, and stretch cloth over it and snugly staple to the back of the luan. You can then lean these about against whatever, mount them on wall or on stands, could make bifold floor panels, etc. Fiberglass is a nightmare being very unfriendly to deal with etc, is a non-starter. I know from experience, made a few covering them with cloth..bad idea. Oddly, polyester batting seems to be at least fairly easy to get in some other countries, but not USA. Though I think you can order it of course. But yeah I will be trying to order some. Also, besides not being a stellar performer, studio foam disintegrates after several years and makes a giant mess, sticking to where its been and to floor it falls on. I will maybe be sharing a vid about that soon.

    Malheureusement les tests qu'il fait n'ont absolument aucun sens !!!
    1) il utilise une fréquence précise pour tester. Même s'il en fait plusieurs à des fréquences différentes, en l'occurence 13khz 15khz 17khz, cela est une vrai blague en vue du nombre de hz non testés. Entre 13khz et 15khz il y a quand même 2000 hertz non testés.
    2) Pour mesurer l'absorption du matériaux, il le place entre le haut parleur et le micro de mesure. Cela n'a aucun sens !!!! Si ce n'est de vérifier l'étanchéité acoustique du matériau.
    Imaginons qu'il test une plaque de métal, avec son test il aura l'impression que la plaque absorbe le plus, alors qu'en réalité la plaque et bien le matériau qui absorbera le moins.
    Pour faire au mieux, il faut tester le matériau dans son contexte.
    En gros, on met une mousse dans une pièce (une salle), on mesure la pièce avec la mousse et sans la mousse, on fait la différence et on a le résultat d'absorption.
    Bref sa vidéo est catastrophique....

      Oui effectivement pour les basses il y a plus efficace que cela, mais bien plus complexe à réaliser. Toutefois le principe est le bon, plus c'est épais, plus c'est efficace vers le bas du spectre, mais il faut bien accepter et reconnaitre que pour absorber des basses fréquence aux alentours de 50hz il faut environ 1 metre d'épaisseur... c'est dire... Cependant les panneaux en laine de roche ou de verre, auront un bien meilleur rapport qualité prix que des serviette de toilette. Mais, je te recommande vraiment de les recouvrir avec un tissu, pour ne pas répandre partout de la poussière, qui au passage n'est vraiment pas recommandé pour les bronches. Si tu veux vraiment avoir des panneaux nus sans tissu et bien plus sain pour les poumons, cherche des panneaux de chanvre, lin ou coton.
      Par exemple ici :

      Ah oui merci je viens de voir (tombé sur RockWool) et j'ai lu dans les com d'un tuto que pour les basses, il suffit d'augmenter l'apaisseur (plus on rajoute des chouches, plus on descends dans les basse fréquences), j'imagine que ce n'est pas aussi simple et efficace que c'est dit mais bon ça semble être la meilleure solution fait maison. Merci je vais donc suivre tes conseils et je pense même me passer du recouvrement esthétique (cadre en bois, tissu...), ça sera donc : toile de roche nue sans rien, histoire de pouvoir les trimbaler où et quand je veux :)

Cherche sur Google, panneau acoustique laine de verre ou de roche, tu trouveras 10 000 tutoriels sur le sujet, c'est absolument, sans aucune hésitation, le meilleur rapport qualité prix efficacité, pour ce que tu veux faire. Pour traiter les basses c'est beaucoup plus compliqué.. mais sera déjà bien pour les médiums et aigus.

      Mais là si je suis tes conseils, je ne dois pas me fier à cette expérience (serviettes) et revenir vers des panneaux pro ?

    This may have been mentioned (certainly haven’t read all the comments), however one of the advantages/selling points of the Auralex panels is that they are fire retardant. In a commercial environment, it’s against firecode to hang something on the wall like the DIY towel solution. On the other hand, this is obviously a great home solution, but you do still want to be aware of the fire risk. I may build a bunch of portable version of these!

    A popular aphorism is “The proof is in the pudding”. Your tests demonstrate this axiom. The panels do what they were intended to do, reduce sound reflections by stopping transmission thus helping to reduce the acoustical reverberations of the room. Other words by adsorbing the sound “transmission” you have reduced the “refraction” and thus the “reflection” of that sound. Your sound absorption panels are far more appealing than just hanging moving blankets on the wall. Rightly done indeed.

    i´ve dealt with some studio high, mid and low frequency rage absorbers. The goal of these is to reflect the energy of certain frequencies again and again inside until their energy is, more or less, gone.
    Usualy they archieve this with open structured foam where the sound energy can get into and "get lost" in a sort of labyrinth.
    Of course the towels work, as their surface is a caotic structure and the soundwaves will get reflected in random angles and therefore get diffused and less "hearable" but they only work for rather high frequencies, if you also want to ged rid of mid and low frequencies, you would need to make the labyinth path longer and longer, until several meters for the lowest range, if you hear some "booming" in your room...that´s not an easy task to place some fridge sized things in the room corner(s) but that´s how absorbers work, they absorb ;)
    Anyway great video, and a good and cheap way to DIY acoustic absorbers for mid and specially high frequencies.

    Hi Matt, I am a fan and enjoy watching your videos. I'm sure what I'm going to say has already been addressed, but here's my 2 pence worth: the purpose of acoustic foam is not to stop noise from being transmitted to another room, but rather to stop sound from being reflected back into the room sounding like the inside of a fish bowl. It does so by providing a multi-faceted, multi-layered surface so that sound waves lose their energy.

    You should leave a gap between the wall and material and more gaps between more layers used, it sounds like a waste of space but its significantly more effective, it allows the sound waves to bounce around a bit so more time for them to be absorbed.

    Is it the sort of pointiness of the towels that makes them so good at absorbing sound? The actual texture means that sound will bounce off one point of fabric, into another, into another, and so on rather than bouncing a bit and then heading back out of the material, right?

    First of all, your sponges are probably closed pore materials. Second, with what did you perform your measurements and what method you used? Third, most problems in small to medium rooms are in the low frequency range due to room modes.
    Also regarding measuring transmission and reflection are both coupled. Sound propagation phenomena are: Transmission, Reflection, Absorption and diffraction. The three first are important here. You can have small transmission but no absorption because the material is reflecting sound. Therefore to test correctly the absorption of a material you need to measure the reverb time in a room previous to applying a certain surface of the absorbing material and the reverb time after. Thanks to the Sabine formula you can obtain the α of the material for 1/3 or 1 octave bands and establish the properties of the material. Everything else is little scientific and based on the perception that obviously, anything you change in your room will make it sound different in certain frequencies.
