12 Pack Acoustic Panels Sound Proof Foam Panels 12 x 12 x 2 Inches Black Fireproof Soundproof Acoustic Panels for Walls Absorbing Noise Cancelling Panels for Recording Studios, Home, Offices Walls Cei

Summary:Ok, so I bought the 12 pack and lined the wall, 2 rows of 6 just behind my monitors in my Twitch studio. And let me say that WOW what a difference these make. My voice is amplified inside the room, but with the door closed and my family standing on the other side of the wall they say they can barely hear my voice or my "clicky" mechanical keyboard. Inside the studio I hear myself much more clearly and the sound my mic is picking up is already better!Unpacking:So, what about making them expand? Well, while leaving them out will probably do the job, the soak-wring-dryer method works best. I did a control with a few panels left out and the rest i did this method of wetting, wringing them out, and throwing them in the dryer on medium heat for 1 hour. When held side by side, the ones I just left out on the counter were 1/4 inch shorter in depth than the ones i did the cycle with. The second you wet these things, the foam fully expands, throwing them in the dryer is just to get them dry again.Installation:I installed these with Scotch indoor double sided mounting tape. I find this tape to be very forgiving on your wall's paint if you use your thumb and roll it up off the wall like a carpet. It leaves nothing behind and when it does, just rub the remnants with your thumb and they will flake off. However, if you try to reposition a panel, expect it to tear off some foam, so be gentle.Final Thoughts:All in all I highly recommend these. I did a lot of shopping on amazon and these are the best ones on the site. They are consistent, well made, no miss-cuts and I will be ordering another 24 of them to finish wrapping around my entire area to catch all the reverb. Couldn't be happier for 20 bucks.

[Please note these tiles are for acoustic TREATMENT, not SOUNDPROOFING. They helped reduce the reverb in my room, though I can definitely still hear outside noises from the windows. I bought these specifically for the treatment and not for soundproofing since the latter requires a far more intensive process than just slapping up tiles on a wall]9 of the 12 tiles I received were perfectly fine after tossing them into the dryer for 10-20 minutes on the lowest heat setting. The other 3 I had to soak in water for a few minutes, squeeze the water out, and then toss again into the dryer. Turned out great!Command strips work perfectly fine (I put two on the top left and top right when hanging the tiles up on the wall) as long as you press on the strips for a solid 15-30 seconds.-0.5 stars because of the chemical smell they gave off initially. It has been several days and they're much better now, though you can still get a sniff of it if you put your nose directly onto the tile. Otherwise, it's a great value product!

The foam is durable and I can hear the difference with only 12 panels, which I installed on a wall behind a drum set in a small 140 sq ft music room. I ordered two more packages (12 panels each) with an aim to control the sound even more. I attached it using a staple gun, which causes the foam to distort around the point of the staple's entry (see photo). I don't mind this but if you want your foam to look even, you'll probably consider using some type of adhesive. Lastly, the foam panels give off a chemical odor but subsides after a few days. I would suggest opening it and setting it ouside for a few hours or days before installing (give it time to air out) if you are sensitve to chemical odors.

Not that bad but still heard a lot

I use these to reduce echo around my mic setup on my computer. It works really well, but that's really to be expected because it's just foam--it's not some crazy space age material or something.If you're looking for soundproofing, this is not it, but that's not what it's designed to be, either. It works great for echo reduction.One complaint is how much effort it took to get these to expand to their 2-in height. They're packed really tight, and to get them to expand I had to vigorously massage them underwater in the sink for a couple minutes each. Then I squeezed (I don't think wringing them would be a good idea) them out and left them out to dry for a day. If you work them enough in the water, they will grow to their full height and all the ridges will be even.I used a couple command strips each to attach them to the ceiling. If you align the command strips with the ridges the foam flexes downward a little less than if you don't.

I was so excited to get these and when I opened the box they are super thin because they are vacuumed sealed. Then when I open the plastic package, OH MY GOSH the SMELL was horrendous! It smelled like very strong chemicals and these were going in a small room and there's no way that smell will go into my lungs! I left the one open package overnight downstairs, and in the morning they did expand but not very well, they are crooked and it still smells!

These tiles do a passable job of absorbing background noise, which is the only reason this is not a one-star review. The installation was a figurative disaster. I took these out of the package a full week prior to the planned installation and let them sit in a well-ventilated area. They did not return to normal size; not even close. They were cheap enough that a bought a second set to try again, but the second set was even worse.I tried the alternative instructions, i.e. soaking them in water, wringing them out, then putting them in the dryer for 20 minutes. Even on low, half of them sustained some sort of damage in the dryer. Good thing I bought a second set.I purchased the recommended 3M pads for installation on a plywood wall. The 3m pads suck to the wood just fine, but the foam tiles fell off repeatedly. In fact, two of them fell on me while I was typing this review.I would not recommend this product. If you've already purchased it and are looking to make it work somehow, I recommend a staple gun. The result will not be as visually appealing, but I could not find any other way to get them to stick to the wall or ceiling.
