12 Pack Self-Adhesive Acoustic Panels, 12" X 12" X 0.4" High-Density Polyester Sound Proof Foam Panels for Walls, Soundproof Wall Panels for Home & Office (Black)

Used a bunch of these for my gaming area. Solid construction, feels durable. Should help slightly with sound dampening. No obnoxious smell. Back adhesive covers the full back and they’re very sticky and I have confidence they won’t fall off. Make sure you measure everything because they’re pretty sticky and takes effort to pull off once it’s on.

Using them to darken up and sound insulate my home theater room.They look Great and easy to install.

I bought these to help sound proof a home studio. These are much easier to work with than soft foam panels. They cut easily with a razor knife, stick great, and look very good as well. I was able to build a small vocal booth using rolling walls covered with these panels. Good buy!

They stick to the wall nice and look great but they are a little thin, doesn’t bother me enough to change it. If that’s a problem you could always buy 12x12 foam board elsewhere and put it behind these.

Installed on the back of the bifold laundry closet door to cut down on the noise from the washer and dryer. Cut the noise by probably 2/3. Sticking to the back of the unsealed hollow door well.

Purchased these for surrounding my Golf Simulator. Found some other foam type panels much cheaper so ordered them and was going to return these. I used the other products for around the simulator but ended up using these panels for the ceiling. They look sharp and work well. They even hold up to golf balls that have bounced and hit them with no damage. Just ordered another 20 pack. Thanks

I think if you want to use this to reduce echos in your room specifically, it is a good product. But it does not reduce or prevent sound from leaving a room. The only way to really do that is to rip up drywall and install the soundproofing inside the walls.The sticky residue it leaves behind if you take it off is also a pain to clean up.

Installed panels behind TV to block the light walls and provide additional sound protection. Very easy to install and provided the much needed dark back drop.
