Woanger 5 Pack Large Acoustic Panels 47x24x0.4 Inch Sound Dampening Panels Self-Adhesive Noise Absorbing Sound Proof Wall for Echo Absorption for Home Studio Office Game Room(Black)

The easiest setup no mess. Did the job, muffled the neighbors noise. I’ve had these up for 6 months and they’re still attached to walls.

Update: 3 months later, it works. We no longer hear a booming, reverberating sound from our neighbor’s sound system.We wanted something sound absorbing for the wall we share with neighbors. So far so good. It was really easy to install and looks great- adds some coziness and warmth. Still not too sure how much sound it will block but we figure with how thick the panels are, it’s got to be better than nothing

I bought this to put behind my TV as useful accent wall. Very easy to apply and cut. Made a big impact without hurting my wallet. It was less commitment than painting the wall in black with designs.I was going for art/useful/low commitment. Would buy more and recommend. I would give it a 4.5 because it helps with noise reduction but not a whole lot.

I put them up on a shared (uninsulated) bedroom wall so I wouldnt hear my daughter snoring. I also use an air cleaner which produces white noise. between the 2 I can no longer hear her! problem solved.

As another reviewer pointed out, these panels have arrived with mold spots covering them in various places. The panels are also slightly shorter than advertised, so if you were taking precise measurements of your installation area you’ll need to remeasure once your panels arrive - maybe you’ll be lucky and get some that aren’t moldy! I cannot recommend these panels or the seller. I wish they had worked out because it seemed like a potentially easy panel to use, but alas, I’m not using anything moldy.

Have had it up for a while it reduce spread of sound

These have a very strange smell almost like mildew

SUPER easy to install with adhesive even on angled walls. Large for substantial coverage. I read some people complain about smell… mine had none. Pre and post room correction showed noticeable improvement, but what really matters is how things sound… and it’s remarkably better. I have an 11.2 Atmos system powered by Denon Receiver and Emotiva Pre-amp … and I wish I would have done this years ago.
