Auralex 2 Inches Studiofoam Wedgies 1 X1 FootAcoustic Panel 24-Pack - Charcoal

The media could not be loaded. 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 Proofing2) Acoustic Sound Treatment1) 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.

I really like these panels. I ended up purchasing more to fill my entire room. They are on prime so I can get them quickly and I didn't have any issue placing them on my wall. I even put some on my door. Once the entire room was covered you it was prime for recording.

QUICK SUMMARY: Worked to deaden the reflected sound in a small nook of my bedroom that I've turned into a recording studio. Seems like a lot of money for foam, but I'm no sound engineer.BACKGROUND: I've turned an unused make-up counter in my master bedroom into a home recording studio. The built-in make-up counter is walled-in on three sides with a large mirror behind the countertop. Without treatment, the sound was reflecting mightily off all the hard surfaces. On a recommendation, I ordered these Auralex Studiofoam squares to dampen the sound in this area. It worked! The space I'm working with is approximately 2' x 3' x 2'. Ideally, I need 21 squares to cover the walls 3' up from the countertop, and another 6 squares to create a hood over the countertop -- 27 squares total. This set only has 24 squares, so I'm missing a few squares on both side walls right now.INSTALLATION: To attach the Studiofoam squares to my walls and mirror, I used Velcro squares I cut-out from industrial-grade Velcro tape. I only used two small, 1" squares of Velcro per foam square. Seems to work so far to keep the feather-light foam panels in place. I did also try using 3M Duct tape (black, which has moderate adhesion properties), and that didn't work at all, which surprised me. For the hood over the countertop, I used small picture frame hooks and 28-gauge picture frame wire to string thin strands of wire over the countertop, then laid six Studiofoam squares on the overhead wire. That worked very well, but it doesn't look too nice, because the wire does tend to sag a little. The benefit of this whole arrangement is I could completely remove all the squares anytime I want, as none of them are permanently attached to anything.PERFORMANCE: After installing just the squares on the three walls, I sampled my voice above the foamed walls and within the foamed walls. It was very, very noticeable the difference! My voice sounds "dead" when I'm talking into the foamed walls, meaning that it sounds weird, almost muffled (it's not really muffled, of course, it's just that it's harder to hear my voice because so much of my voice energy is absorbed by the foam squares). For my purposes of voice recording, this will really be very beneficial.CONCLUSION: I'm not a musician or recording artist, just somebody who has a need to professionally record my voice at home without a big investment. To me, spending a hundred bucks on something like this is a fairly big investment since it looks just like foam padding you'd find when unpacking a new TV set from its shipping box. Be that as it may, these are doing the job they're intended to do, so all I can quibble on is their price. Recommended!

Will work great for small rooms, booths, closets ect. Blankets and clothes are much cheaper and results are similar for alot less. Big rooms should avoid this and go straight to panels.Edit* Had to remove a star. This stuff smells horrible, I'd wash it in cold water before hand. The plastic smell is overpowering, especially in a small space.

These panels used to be great - I've ordered them twice in the past, but the most recent order was completely different quality and clearly was fake. Do not buy these, they are not as advertised. They will not dampen sound.
