Sonicism 12 Pack Pyramid Sound Proof Foam Panels with Self-Adhesive, 12" X 12" X 2" Acoustic Foam Panels of High Density, Soundproof Wall Panels Fast Expand, Sound Absorption and Decoration (Black)

I used these to reduce sound from the engine compartment on my boat. Easy to cut and easy to place. I did use spray adhesive as it gets hot but I may not have needed to as the adhesive on these is very strong. End result was terrific. Before, hard to talk over the noise. After, easy to have a conversation. Highly recommend.

Overall we were happy with the product as we bought enough to help soundproof a 10x12 room that we built for shooting video content for digital media. Out of all of the panels we purchased, we had 3 or so that after time didn't adhere, but it could have been due to the humidity in the room since it's been a 100+ weather here in Texas for the past 3-4 weeks now. They provide a good adhesive tape with the product in case you have a panel or so that doesn't stick. Other than that, it is a really great quality product, and one we would recommend to those who are looking for noise cancelling/absorption for a space they are trying to soundproof.

These Sculptured Closed cell Foam pads are good for reducing high frequency sounds. The self adhesive makes this "kit" of panels easy to insyall.

Used these to soundproof an Iso-cab. Granted I had to use a staple gun to mount the sound proofing inside the iso-cab. But they worked perfect. Before sound proofing the room Db was at 85 After adding the sound proofing inside and fully covering the outside with the sound proofing then covering those with the Amazon moving blankets 1 layer as a outer covering. Room Db dropped to 32db Im am running a 50watt tube amp at about 30% VOL. its very quiet!

I'm using these with felt boards on smooth painted walls. They don't always hold, and the boards come off the walls. Also, they DO NOT remove cleanly. While they don't leave a residue, they also take the paint off the walls.

Wow these squares are not all the same size. How in the world are you supposed to line them up right and make everything uniform when they can’t even provide squares that are all different sizes. The foam is also very flimsy. I was expecting a decent density.

These acoustic sound absorbing panels look just as good in person as they did online! I was afraid to get them and find they were thin, light and foamy. But these are nice and dense and the pyramids give it an extremely cool, professional look! I did have a couple issues that I contacted customer support about. First, I was impressed that they clearly display their email address on a flyer in the package to insure the customer can count on support if they need it. Within just a few hours of emailing them, they got back to me with a solution and happily made it right! Next time I need more, I won't even bother shopping around, I'm so pleased with this product and customer support! The tiles stick great to the wall, but can also be removed without any damage to the foam or the wall. Even though these are peel and stick, they also come with adhesive squares if you need them. So far I have not needed them. Some of these panels fit near perfect into my desk wall shelving, so I just pushed them back in each one and they are snug enough where I didn't need to peel and stick them. But I also have some installed on the wall, and those are holding very well. This room was a bedroom with a twin bed, plus a home office. But I decided to make it just an office space with another desk and computer, so I moved out the bed. I couldn't believe the sound difference. Without the bed, everything was echoing, loud and just made the office have a "cold" like environment. Even just typing bothered me because it just sounded too loud. I didn't even like talking in here. It's amazing how just by hanging some panels on the wall changes the whole environment into a room you enjoy being in. If you've never tried sound panels, the price is worth it, especially considering how much it can improve the comfort level of a room. They are not just for professionals or sound studios. They would also be great for a kids bedroom, and you might find you won't have to turn up the living room TV so loud anymore ;)

Bought these to sound insulate the ac unit in a closet. Were easy to cut and stick to the walls and the vast majority have held... a few needed to be pressed in place later. Sound wise, using a decibel meter, they made a pretty decent difference in the sound coming out of the closet.
