Upgraded 36 Pack Self-Adhesive Sound Proof Foam Panels for Walls 12" X 12" X 1"， Fast Expand Acoustic Panels with High Density, Pyramid Soundproof Wall Panels for Studio and Home Noise Reduction Black

Great quality foam panels work well in my hunting blind to absorb noise and insulate from the cold. Adhere securely to the walls of the blind. Some panels arrived flattened, but I laid them out in the sun and was able to pull them into shape with no issues. Good value too.

I'm a professional audiobook narrator and need some sound treatment for the ceiling in my home studio. I saw these and was impressed by the fact that they were self sticking. Working to install them on the ceiling was where the self sticking feature really shined. The panels went up quickly and easily, stayed in place and they look good too! The addition of these really made a difference in my studio. My ambient noise levels are now much lower. I could have spent three times as much on some overpriced panels but these did the trick and I love them. I would highly recommend them to anyone looking for sound treatment.

These are a bit on the cashy side. Also, it is extremely difficult to install. What I mean is keeping the rows lined up between tiles can be difficult to impossible. Not all of the tiles are the exact same size. The acoustical properties are awesome! I used these in my air compress/dust collection closet and the difference is amazing. I can now barely hear the air compressor now. Definitely cannot hear the dust collection system anymore.

I received my panels and like some of the review mention, some were flat. I have 7 panels out of 24 that had some flat rows. I reached out to the manufacturer (like the insert card in the box says), and they actually sent a video about how to fix the problem. It worked on some of the panels but a few stayed flat. I let them know and they replaced the panels for me. I didn't really expect much since these are really inexpensive panels but they honestly work great and the company that makes them really backs up their product which is awesome. Very happy with this experience and will likely be ordering more.

A part of the pack came smooshed and unusable. Sadly, these are uneventful for reducing noise. They peel & stick fine, an eye sore and now I need to cover the door I was trying to sound proof. I would have returned them but they were already stuck to the door and seemed like too much work to bother. Sorry to say these have not helped my sound reduction issue. Best of luck

As long as the panels stay in place they help to muftle sound, but mot entirely. However, I had to find another adhesive to get them to stay on the wall as the panels started falling off within a couple of days. The added double-sided adhesive squares that come with don't hold to the panels well.

They're really easy to apply, and they work well.

So I've recently tried this type of product from three different manufactures. This product is substantially better than the others while still being at the same price point. The biggest difference is the recovery time, how long it takes the product to expand after being compressed in a vacuum sealed bag. All 12 squares fully expanded & recovered within 3 seconds! The other products I tried were extremely disappointing, it took about two weeks for 50% of the squares to recover and the other 50% never recovered. I will say the adhesive back works as intended and is roughly the same quality across all of the brands I tried. I know it's probably very cheap to manufacture this type of product... However it's apparent that this particular manufacture doesn't skip corners in the manufacturing process & they have someone in quality control that knows what they are doing.

El producto tiene buena adherencia, sin embargo no hace mucha diferencia en la acústica ya que no es muy grueso ni denso. no creo que sea una espuma ideal para un tratamiento acústico

Muy buen producto y calidad
