Focusound 50 Packs Acoustic Foam Panels Wedge Soundproof Studio Wall Tiles Sound Absorbing with Double Side Adhesive Tape, 30 X 30 X 2.5 CM

Before buying these, I read pretty much all of the reviews. Most were positive, but there were some negatives. I bit the bullet and ordered them. They're up, and here are my thoughts: 1. People complained that many of their tiles never expanded. Yes, they come squished tightly together in vacuum sealed bags, and that flattens them rather effectively. However, I immediately dampened my tiles under the faucet, wrung them out, and ran them through the laundry drier. They popped right into shape. No issues. There were some that were more squashed than others, and I set those aside to see what they did on their own. Two or three hours after unpacking, they weren't quite as thick as the ones I dampened and dried, but still about 90 percent back to their intended thickness. They were fully expanded the next day. Considering the instructions say to give them a day or two, that's pretty good in my book. 2. Others say their tiles smelled weird. Mine didn't. At all. No smell that I could detect. 3. A handful of reviews claim their tiles were cut at wonky angles. Mine were perfect squares. I ordered the 50 pack and all 50 have 90 degree corners. 4. More than a few said the double-sided tape for hanging up the tiles didn't work for them. I have had zero issues so far. I think it depends on (a) how much pressure you use in pressing the tape to the intended surface, and (b) the type and cleanliness of the surface you're sticking them to. Tape sticks better to some surfaces and not so well to others. In my case, the surface is raw cedar paneling. Also, if there's any dust or smoke residue on your walls, the tape won't adhere to it very well. So I'd strongly suggest making sure the surface is clean before trying to stick things to it. And give the tape a good hard press when applying it to the wall. It helps ensure adhesion to both the hanging surface and the tile. 5. Some reviewers complained that the tiles don't block sound. News flash -- acoustic paneling isn't meant to STOP sound. That's what wall insulation is for. It may help DEADEN sound, but that's it. I bought mine for a 6x8 recording studio. I have curtains, soft furniture, and a thick area rug to help deaden sound and cut echo, but the cedar panel ceiling was echoing and I had to eliminate that. I started with 25 panels on the ceiling above my recording equipment. That equals two thirds of the ceiling. As soon as they were up, I recorded a minute or two of test audio, and voila -- the echo was almost completely eliminated. Not bad, if you ask me. I plan on putting up the rest, but I'm done for now. I'll update when I have the rest of the setup completed. For my initial impression, I'm giving it 5 stars. UPDATE: 1 week later, here's my report. The day after installing the tiles, one of the tile had a corner come loose. I pressed it back up and it stayed. No adhesion issues since. I have also tiled the rest of the ceiling and my echo issues seem to be pretty much eliminated. So my 5-star rating remains intact.

Ces panneaux acoustiques remplissent bien leur rôle en absorbant les hautes fréquences et en réduisant la réverbération dans une petite pièce. Ils permettent d'obtenir un son plus mat et moins échoïque, ce qui peut être utile pour un home studio ou un bureau. Cependant, il ne faut pas les confondre avec une solution d’insonorisation : ils ne bloquent pas les bruits extérieurs ni les basses fréquences. À utiliser en complément d’autres traitements acoustiques si l’objectif est une isolation sonore efficace.

The value for this dampening material can't be beat and it works well for certain applications. My application wasn't one of them unfortunately the sticky tabs for mounting to surfaces didn't work for mounting to the car door panels. I definitely believe the foam will work but in order to secure it to car panels you'll need double sided tape or something a bit stronger

This is good quality and works quite well. However, it is permanent. Once laid, does not come out without destroying the wall.

These Acoustic foams are great!!! I put them up on my living room door and behind the couch, the sound got way better!! The service, packaging and delivery was great too!
