Auralex Acoustics Studiofoam Wedgies Acoustic Absorption Foam, 2" x 12" x 12", 24-Panels, Charcoal (WEDGIE-24)

This is (by lab test results and general opinion) the best Acoustic Foam Brand out there currently. In my studio, it did exactly what I needed it to do, and I can confidently recommend it. However, you need to know what this is for, I'm not a sound engineer, but this is what I've gathered from a month of looking at tons of videos and reading tons of forums to learn how to sound treat my studio. Also, English is my second language but I'll do my best to explain this clearly. There are two different types of sound treatment, and I really mean they're TOTALLY DIFFERENT: (I'll explain) 1) Sound Proofing 2) Acoustic Sound Treatment 1) Sound proofing: This is when you're trying to make it so no one outside a room hears what goes on inside the room, and vice versa. This foam is NOT FOR THIS PURPOSE. This foam will NOT make your studio/room sound proof, so please don't give it a bad rating if you used it for the wrong purpose. 2) Acoustic Sound Treatment: This is what this foam is for. It will catch sound frequencies (specially high and mid frequencies, but definitely not the bass) when they try to bounce on the walls and will absorb a little, and scatter a little in order to reduce the echo or reverberation effect. This will in turn make your studio/room sound "dead" which gives your ears a chance to hear your mix a lot more accurately, and without the room adding it's own sound effect to your creations. In laymen's terms, it absorbs some of the sound because it is porous and waves that try to go through bounce so much they lose momentum and die, and the waves that don't go through get broken up by the pyramid shapes and sent back weaker, and spread out. With that said, there are better ways of treating a studio than this foam. I recommend you look into Fiberglass Panels made with "Owens Corning 703" a quick google search will yield tutorials on how to make these bad boys yourself, and they're many times better than this foam, I guarantee it. I personally use this foam for the ceiling of my studio, and in my recording booth for the ceiling, and a small part of the wall lining. I use the Fiberglass panels for the walls, this combination of the two has yielded Amazing results. How to Adhere: This is a very common question in forums, and every person will give you a different method. Here are 2 of experiences with them, and how I managed to get them on. First attempt - The not so good 3M Super 77 Multipurpose Adhesive Spray method: I wanted to be able to remove them when I move, so at first I tried this 3M Super 77 and sprayed it on the back of the wedges, then put it on the ceiling. That was a DISASTER. I came back the next day to find all of them all on the floor, and I had used the spray generously. To fix this, I sprayed the wedges again, and I also sprayed the area of the ceiling where the blocks are going to be, with adhesive on both ends, it works a lot better. BIG FAT RED WARNING: This spray creates a mist, that could potentially fall on your equipment, and make it sticky for a good while, so if you go with this spray, cover the gear below with newspaper while you spray it on the ceiling, and spray the foam blocks into a piece of cardboard, or outside. The second and better method - 3M High-Strength 90 Spray Adhesive: This spray is a lot stronger, and it shoots a kind of silly string, so it doesn't create the sticky mist that other one does, thus it's a lot safer to use in your studio with all your expensive gear. The only downside, is that once you stick it, it's a lot harder to take off the wall, albeit not impossible. To use this spray you MUST SPRAY BOTH WALL AND FOAM, otherwise it will not stick. Another Tip: This foam works better when you change the direction of the pyramids with every block, as to create this pattern: ≡|||≡|||≡|||≡|||≡|||≡ |||≡|||≡|||≡|||≡|||≡||| ≡|||≡|||≡|||≡|||≡|||≡ |||≡|||≡|||≡|||≡|||≡||| Please let me know if there's anything that should be added, or corrected here.

24 pieces of 12in x 12in acoustic foams for under $100 is an inexpensive way to improve room acoustics. It removed all perceptible echos in my room. Made my stereo sound better by reducing bounced-sounds from the speakers. And the TV seems to have more clear dialogs. Overall, I'm very happy with the product. It came in a big box, uncompressed & not deformed. I'd rather receive it this way than in a bag that was vacuumed. Less chances of being deformed & no need to wait for it to come back to its normal shape. I didn't notice any strong smell as other reviewers have indicated. And it has a fire rating which is important especially that I placed it in my bedroom On some reviews...I've read a few people comment on reviewers trying to pop their bubble that this foams don't have any soundproofing abilities in them. So here are a few questions for you know-it-all people: 1. If the Auralex Studiofoam has a NOISE REDUCTION COEFFICIENT (NRC) rating of .80, meaning it absorbs about 80% upper-mid to high frequencies...does it mean that it does NOT reduce the sound transmission to other materials behind the foam? 2. Then you would argue that soundproofing is the art of isolating the sound from one room to the next or from the outside world. And sound absorption does not stop the transmission or movement of sound. I would counter argue: if parts of the sound have been absorbed by the foam then the transmitted sound have been reduced. Is it safe to say that a reduced sound is a quieter acoustic transfer? 3. If the foam can absorb some frequencies & reduces the amount of sound being transferred from the foam to whatever material behind it then isn't having some sound-absorbing abilities also the same as having some soundproofing abilities? I am not an acoustician but a big part of sound is subjective dependent on how each individual perceives it. Yes, there are scientific ways to interpret sound but there is no concrete evidence if there is a standard way of how individual brains interpret perceived sound. So just because these people have read definition of things on the internet doesn't mean they have keener or more sensitive ears than everybody. If a reviewer says that he thinks his room got quieter after he installed these foams then that is his perception. Read reviews as you please, take it with a grain of salt and no need to pop other people's bubbles by commenting on their reviews that they're wrong.

I've spend over $1000 on these, and I cant get enough. They are very useful, and efficient. Compared to other acoustic foams I have tried, these take the cake. A little pricey for a piece of foam, but it does its job.

La utilizamos para quitar el eco en nuestras oficinas y funciona muy bien, además que tiene un diseño muy padre y se vuelve más cálida la oficina. Sólo que el precio es alto.

Expensive but super high quality! Way better than other cheaper competitors

Muy buenos paneles. Vienen los 24 en la caja y totalmente nuevos, bien empaquetados. Lo que dice la publicación eso es lo que viene. Los probé inmediatamente y van geniales. Prónto voy a comprar más. Excelente vendedor.

Massively improved flutter echo and general acoustics in my 12*14*7 live / recording / mixing project studio. Used with lenrd bass traps, very happy
