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.

Value Rating: 4⭐️ – These are a bit pricier than some foam alternatives, but they offer a unique combination of being ultra-thin while still dense enough to be effective. The full adhesive backing also adds value since there’s no need to buy separate mounting strips. Specifications: • Set of 12 panels • Dimensions: 12” x 12” x 0.4” • Material: High-density polyester fiber with a damping rubber backing • Self-adhesive backing for easy installation Key Points: I’ve purchased quite a few different types of sound-dampening panels from Amazon, and these stand out because they are so much thinner than most, yet incredibly dense. The adhesive backing is a huge plus—it covers the entire panel, so there’s no risk of them peeling off over time like some foam panels. The thin design makes them more versatile, allowing them to blend into a space without looking bulky. Final Thoughts: If you’re looking for a low-profile soundproofing solution that actually stays put, these are a solid choice. They’re a little pricey compared to basic foam options, but the quality and adhesion make up for it. I don’t have any complaints!

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.
