12 Pack Acoustic Foam Panels 1" x 12"x 12" Soundproof Panels Black Sound Insulation for Wall Absorbing Fire Resistant Acoustic Dampening Wedges Home Office

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.

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.
