12 Pack Hexagon Acoustic Panels Beveled Edge Sound Proof Foam Panels, 14"X13"X 0.4" High Density Sound Proofing Padding for Wall, Acoustic Treatment for Studio, Home and Office (Grey Black)

Does what it is supposed to do. Get some adhesive dots that are designed for foam, and use the water expansion method to resize the tiles after shipping.

I recently used this stuff in a project to build a sound dampening box for an external generator on my RV. The box implements a few different design choices for noise reduction, but this foam worked very well in my application. I've gotten the generator down from around 95 dd idle to about 70 db idle.

I meant to purchase the ones with adhesive but these looked pretty good.

Arms itched like fiberglass after handling. I question the "non-toxic" claim considering my dermal reaction.I have them mounted and they seem to work.YMMV.

I got these soundproof foam panels to solve the need for sound-absorbing dampening for a large sound room. These panels are high-density with a fire retardant. I liked the style and quality. However, they are not all the same size, resulting in an uneven look. This was a problem because I wanted to make the panels look like a work of art on the wall. But the inconsistent sizes spoiled it. Overall, it functions as expected with the noted issue with sizes.

They look great and are well priced. Took 15 mins to set up and was definitely worth it. Only issue is it doesn’t help too much with the sound. Cant hear normal conversation on other side of the wall, but anything louder is clear.

I used these to line a shop vac box in my work area. The high pitch sound it makes is gone, and the overall volume and other noises seem to be about half of what it was before the foam was in place. I used a few lines of E6000 to secure the panels in place and so far they haven't budged.All panels expanded to proper size and shape once soaked, though they took longer to dry than expected. The material is super absorbent

I sed this pack to do the inside of a shop vacuum/dust collection box i built. The db in my garage with one or both running ranged from 88-100db before install. Now its between 76-94db. Not what i should have used but as far as constant tone decrease good purchase

Does the job as expected. They are not very thick so I would recommend not putting them against the wall directly but against a wood base to trick sound.

Really of good quality and sizes are accurate... Happy with my purchase... They are quite big but still not enough..need a few more to complete
