12 Pack Set Acoustic Foam Panels, 2" X 12" X 12" Acoustic Foam Sound Absorption, Soundproof Sound Insulation Absorbing, Acoustic Treatment Used in Home & Offices

If u expect to isolate 100% of the sound, i'll be frank.. is not gonna happen. if ur expectations are to reduce the sounds emitted.. that will work a little. adhesion is 0 if u don't use a spray ( if is ur home ) so not recommended if not for light sound proof room.

These are great acoustic tiles! I read the reviews which mentioned hints and tips of how to get them puffed up and installed. I put them in the sink with hot water to get them all puffed up because they arrive very very flat. They puffed up beautifully. I wrung them out. Then my strong husband wrung them out. I put them in the tumble dryer, 6 at a time for 20 minutes on medium heat. Still a bit too wet to put up and with the electricity costing gazillions these days, I then placed them before the fire because I needed them installed pronto for a voice-over recording session in the morning. I think if I had also wrapped them in a towel and pressed more moisture out that would have helped but i didn't. One person mentioned using builder's caulk to install them but that didn't work well for me. Spray contact adhesive is your absolute best friend here, I promise! Spray the wall and the tile, wait about 15 -20 seconds then fit the tile. Instant deadening begins! For my particular use, I placed the tiles around where I am speaking and on the ceiling above where I am speaking. I think I will buy another packet at some point just to fill in a few spaces but you don't really need many. It made a big difference to the quality of the sound. I remember one acoustic specialist saying that some deadening is better than none! I can vouch for that. These tiles are nice and thick and very very easy to put up.

Much thicker foam over the entire tile than other product I bought. Virtually 2" thick across the entire tile with mushroom type deflection curves. The difference is chalk and cheese when it came to sound proofing absorption!Excellent quality, and I'm going to buy more!
