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.

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 ;)

Product works as intended, but cosmetically a third of the squares had permanent damage due to packing issues. Ass been in pics above, some squares were smashed and deformed. After giving them days to expand and form, nothing changed. 1/3 of the first package I received were like this. Adhesive is strong. Dampens sound very well. It's a hit or miss on the quality tho.

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.

I saw a lot of reviews saying that theirs came damaged. Mine came flat as well, they’re not damaged all you need to do is run your nail, coin, ruler, something hard over them and they pop right back up. Shame people leave bad reviews without trying to fix them :/ as far as quality they do a decent/good job. you’ll need a lot more if you want a huge difference in sound reduction. I used these to keep the sound in because my buildings walls are thin and they definitely work. worried about removal though because they super stuck to the wall. UPDATE: These were super hard to get off the wall. It was very time consuming and was left with grease stains. If you don’t use an adhesive remover they will rip off the paint so be careful!

These work great! Had to use them for when my dogs go to their kennels cause my neighbors downstairs kept bang cause they can hear them at night. Since I placed these under their kennels not a peep from my neighbors, and you can definitely hear the difference when my 125lb dog runs in and out.
