52 Pack Acoustic Foam Panels 1″ x 12″ x 12″ Sound Proof Foam Panles Soundproofing Noise Cancelling Wedge Panels for Home Office Recoding Studio with 270PCS Double-Side Adhesive

They Work Just Fine
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 6×8 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.

It is subjective too falling off the wall still, it reduces echo, however sound still permeates it
Easy install relatively low price, you get extra sticky pads even with 5 per tile, how ever the lack of it traping sound suxs it doesn’t even mitigate the sound going through it and the walls, I wouldn’t recommend it to someone in my position, or in apartments, how ever if you live alone in a house, I’d recommend it, cause it does stop echo, illbeit you do need to mush down on them where you put the sticky stuff at, also pro tip stick your dominant hands thumb in the sticky pad and pull down then you can peal it.

Great sound deadening.
I just had a new furnace installed and it is waaay louder than the old one. I stuck a bunch of these on the door to the furnace and the sound level went back down to the old furnace level. I’m still adding panels to the walls in there and it gets quieter the more I add.Downside… the double stick dots they give you go onto the foam easy but peeling the second side off is not easy. It would be great if they had a tab but I found if I use a small knife tip to go between the sticky pad and the peel off part, it works. Still not easy but it works.

Way too thin to be effective.
These mute nothing. Nada. No effect at all. Moderately cool to look at, but the word “soundproofing” does not, AT ALL, apply to this product.Provides perhaps a 2db reductionon a good day. If you hold your mouth just right, and squint.

This was bought for design rather than to reduce noise. It’s perfect. When it arrived it seemed so flimsy and out of shape. Once unpacked and left for a few days it was great and formed the perfect shape for fitting. Came with tape also.

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!
