Soundproof Wall Panels, 12 Pack Mass Loaded Vinyl Sound Proof Barrier Acoustic Panels Self-Adhesive, 12''x12''x0.4'' Square Sound Proof Panels for Walls, Home Office, Reccording Studio, Ceiling White

Great product quality easy to install , sound levels are decent and do make a difference , especially high mid frequencies .

Within the first night… throughout the night… (I put them out to block out the screams of my baby during the fuss of the night from teething) every single one but three fell off the properly cleaned walls and doors… and made loud ass thud… alll night long… at random. The three that survived didn’t make it past the second day. One held on for three days before falling. Save your money or use tacky tape? They’ve been sitting in a pile at the top of my steps for almost two weeks to remind me to write this review. Can return but likely junk after peeling. Buyer beware.

These tiles are great to use if you want to help prevent echoing in a room. These are not going to block sound completely, that is not what they're for. I took a star because I wish there were more options for applying them than provided. I'm worried that the adhesive will rip the sheetrock when removed and also concerned with how long they will actually stick to the wall. Two opposing problems, I know. There are so many options for removeable adhesives these days so it would have been nice if that was provided. All that said, the tiles seem to be good quality and should help with muffling sound within a room.

I like that these do not need time to expand. They seem very dense. We've been trying a few different kinds of acoustic panels in a home office type of setting, to reduce noise going into adjoining rooms. This set works well, and is being used behind a computer desk to block noise going into an adjoining bedroom. We're not trying to block loud music, but the walls are thin and someone streams from that computer, so the noise can be disturbing to the person trying to sleep in the neighboring bedroom. We're using different egg crate foam panels on a different wall in the same room. These seem higher quality and look nicer than our less expensive egg crate foam panels (which I would expect since these have a higher price point than the foam panels).

The panels feel sturdy, but the self-adhesive didn’t hold — most fell off within minutes, even on a clean surface. I ended up propping them up with furniture to keep them in place. Unfortunately, I haven’t noticed any difference in sound.
