Acoustic Foam Panels Sound Absorbing 12 Pack - 1" X 12"X 12" Sound Proof Panels Noise Reducing for Walls, High Density Sound Deadening Panels Black Wedge for Studio Recording & Office & Home

This is Awesome product, it reduces the noice very effectively, i used that in my kids play area and it worked very well, so i recommend for everyone and it helped my office work as i working from home most of the time , it comes with good amount of thickness that make is sound insulated

I am a shift worker who sleeps in the daytime. Product arrived during a power outage from a thunderstorm, thus I chose the natural method to let product expand. (2 options. Open and leave alone for 24 - 48 hours or Wet the product, squeeze out water, pop it into the dryer on a low setting). Product expanded nicely and appears to be of good thick quality. I will get some double stick tape and apply to bedroom door to help muffle outside noise for better sleep. Once I have tried I will update this review.

Paper thin. Not all uniform in shape. Super disappointed as it was a Christmas gift for my son. Returned!

The 12 pack is just big enough to fill out on the back of a door. They are a nice foam quality. When you open them, they have a small smell. I went ahead and chose the wash and dry them method of expansion, instead of letting them just air out, and the smell goes away. They look like a nice quality and are blackish gray. Overall, you can apply them with command strips or the adhesive of your choice. They filter out sounds okay (took my kids screaming from outside of the office at a level of a 5 out of 5 to maybe a 3.5 out of 5), which is why they get the 4 stars (as I would more hope for a 1 or a 2). I would have to say that since this is the first product of it's kind that I am trying, I am a novice at identifying whether they are really the best at dampening, but they seem reasonable.

What? These squares make it impossible to hear you!

Thin foam

Decent hard to stick.

Panels were unevenly cut and wouldnt puff up since they were vacuum sealed for so long.

tres bien une fois gonflant

Not a single piece has fully formed after trying multiple methods.
