I have covered my door with these panels and problem solved. Not a miracle solution but these sure have made my neighbors slamming doors and yelling more tolerable. I should note they don't do anything for low base noise.Takes about 20 to cover a door.And I used the extra panels on some of the common doors around the house that people have a habit of letting hit the wall when they open them and that has helped to.

Love these. Was a little worried at first when they can so smashed down in a vacuum bag, but do as the directions say and they’ll fluff up to how they’re meant to be. Hanging them was super easy as well. Will be getting more.

I'm still hearing a lot of noise. Needed it for my studio but it doesn't work. By the way, Amazon your employees keep leaving my packaged in the wrong locations. I have to go over to the neighbors to get my stuff.

Got these to put on the back of my sons wall. The other side of his bedroom wall is the mechanical room and the noise carries so I hung these on his sheetrock in the mechanical room. Seemed to help a little bit. Not sure they helped enough that I would purchase again.

Companies that sell echo reducing foam really need to be penalized for calling it sound proofing. Even if a room was fully covered wall to wall, including the floor and ceiling, someone could easily hear the sound of a standard drum being hit by a drumstick. I'm not saying that it won't reduce the volume but it's a full lie to claim it blocks all sound, which is what the phrase "sound proof" means. And same with fire proof. Again if a room were fully covered wall to wall, including the floor and ceiling and something inside catches room with enough heat, fuel, and oxygen, there is no way this foam is going to extinguish the fire and prevent it from spreading. What it can do is self-extinguish the flame on the actual material, which shrivels up. But again, "fire proof" is different.I'm tempted to give a one star rating because these false claims are so common and they need to stop. However, for the real use, of reducing echo bouncing off walls, it's a good product. It's not quite a full 2 inches deep. But is exactly 12 inches square. Shop around because there are other similar products. Currently, with discount, this other product is slightly cheaper, https://www.amazon.com/gp/product/B0CQC5QYSC/ but I like it more, and it has adhesive already applied on the back so it can be stuck on a wall like tape. In my photo showing two pieces of foam, the piece this review is for is the bottom, floppy piece and the top piece with the protective paper covering the adhesive is the product I would suggest considering.

They were packed in a weird way so I had to let them reform before putting them on my walls. But they are exactly what I ordered lol
