Acoustic Foam Panels 12 Pack 1" x 12"x 12" High Density Soundproofing Wedges for Wall Sound Proof Foam Panels Noise Absorbing Blocker and Sound-Damping Black Perfect for Studio Office Gaming Room

The material is thin thus it wont deaden sound, but it’s certainly better than nothing. I use this in conjunction with custom built absorbing panels and these serve as great compliments, especially given the size of my small studio. Love the color and design as well. It is very much used functionally as it is aesthetically. It fluffs up to its full volume in about a day after removal from the vacuum sealed packaging.

I bought this to soundproof a box that holds my rock tumblers. The noise went from unbearably loud to white noise that helps me sleep. I only used it on m3 sides of the inside of the box but I think if I used it on all sides it would be nearly silent.

I ordered the 2” and instead I received the 1”, besides this foam squares are not dense at all, they may be good at canceling echo, but that’s about all they do, they don’t reduce noise at all.

These are nice. Originally paid $19.99 for 12-pack but the price has since gone up which I’m not happy about since I was planning to get more. The product didn’t come with any sticky tabs. Installation is easy…I use t-pins to attach them to my wall (will leave tiny holes in dry wall…you’ve been warned) and they are very secured in place. I got these for decorative purposes and to hopefully deaden some sound. The quality of the foam is pretty good and thick for the 2-inch. They come compressed for ease of shipping; must open the package and let air re-inflate them. They aren’t perfect (a few had bad end cuts) but they work so I’m keeping them. Will purchase again…eventually.

Overall these were a great purchase. I used adhesive and put them in the ceiling of my vocal booth. They do come very vacuum sealed and sucked down to just a few inches thick, meaning they'll need to expand before you can use some if not all of them. I've seen people saying they won't expand back to normal. I have found the easiest way to get them back into shape and get rid of some of that chinese factory smell, is to put about a dozen at a time in the clothes dryer on low for 5 minutes and add another 5 as needed until they return to normal. You may have a few edges or in my case, corners that needed a kick in beanbags with a hair dryer or heat gun on lowest setting to get them to expand. It does take keeping the heat on the edge for a few seconds, so don't move it back and forth too fast. You will soon notice that like some people, it will slowly creep back into its proper shape when sufficiently heated.For installation I used 3M Super77 spray adhesive and gave the back of each tile a light coating, 3 at a time. While they were getting tacky, I measured out the approximate area in the booth and gave it a light coating as well. When both surfaces were tacky, it was go time! Keep in mind these will shrink a bit, maybe 3mm, in the first few days, so pack 'em tight to each other to help counter this issue.So far their performance has been as expected. Nothing to complain about here. I would recommend these to anyone who read down to this point in the review.Peace out!

Works great but does not come with adhesive to stick to wall. Adhesive must be purchased separately so for all that you may as well spend the extra money and get the foam that already comes with double sided tape pre attached.

I ordered 2 of these because I didn't want to run out on this sound-deadening project. The surface area to be covered isn't a simple one since it needs cut panels in order to fit and be most effective.The surprise came when I opened the shipping box and- wondered where they were. (Compressed and in black vacuum packs, almost totally flat and invisible on the bottom of the box.) A plastic wrap around the heavier plastic holding them all so flat took a little time to cut away since I didn't want to damage any of the panels, but after puncturing and then sliding the heavy cover off they began to expand immediately. In only a few hours they were each almost full-thickness and ready to be installed. I used a caulking gun with silicone adhesive (that sticks to ANYTHING) laying them out first and snipping the odd rows to fit. It probably doesn't matter too much it there are small gaps, the sound will still be attenuated. This is a lightweight folding chamber that's large enough to fit over me when I'm sleeping (note: Adequate Ventilation!) because of the noisy fat people upstairs who not only stomp back and forth at all hours but also drop Heavy Objects on the floor - that are like Explosions! (How RUDE!)Ahhhhh! The benefits of not having to listen because there's a solution to excess noise!

These are just basic sponge it doesn’t do anything. I also thought they had adhesive at the back but that’s my fault for not reading the description properly.
