HEMRLY 12 pack Acoustic Panels Self-Adhesive, 12"X 12"X 0.4"Sound Proof Foam Panels, Square Sound Panels High Density, Soundproof Wall Panels for Decoration and Acoustic Treatment-White

These lightweight acoustic panels are exactly what I needed. They look great and each panel weighs only a few of ounces. There is an easy to peel off film which reveals the sticky backing. They sticks well to just about any flat surface. I installed these in a custom made acoustic tower to fill in the gap for my barn doors. The sound absorption was really good and I’d use them again, in fact I ordered a second set myself.

Wow! That's all I can say. Wow! I work remotely and the glass enclosed lanai was echoing so badly on calls. I bought these and set them up (I just set them around, didn't use the adhesive), and they completely stopped the echo!!! I am so shocked. Highly recommend!

Very easy to work with BUT...didn't block sound very well. Have to hear neighbors having sex, fighting, talking. These didn't work the way I expected. Only blocked noises a little.

We set up a home office in our basement. The noise coming from the upstairs could be pretty bad, it felt like we were in the same room. After installing these panels and doing some other basic things, like adding weatherstripping on the door frame, the noise is dramatically reduced. I would say by 80 to 90%. Noise is no longer a problem.

Easy to install. Cut easily to fit. Stick well.
