2 Pack Pyramid Sound Proof Foam,48x24x2 Inch High Density Soundproof Acoustic Panel for Wall,Fireproof Studio Foam Reducing Noise & Echo (Black)

Good quality!
I got the two pack, I wanted to see the quality before I bought more, and they are nice! They look cool and are 2” thick. These are not for sound proofing, only for sound dampening, to stop the sound from bouncing everywhere. They do the job. These come packaged compressed but it’s no big deal, open the package up and they pop into shape in no time, I just left them over night spread out and then they are good to go, the instructions said you could get them wet then put them in the dryer but I didn’t do that at all. In the past in other rooms I’ve had the little squares and I’d need a whole bunch of them and piece them together. These are much better and cover more area, I’ll only need like four more panels to do the job. I’ll be purchasing more of these exact panels and I’d recommend them!

Works great!
My company just moved into a new office, and just like most offices, the soundproofing barely exists. One can hear conversations very clearly from the next room. So I bought this foam stuff, and as it turns out, each individual square is 2″x2″. The window frame on our offices are 2″ wide. So I cut long strips, and stuffed them onto the window frame, all along the top to the bottom (on each side), in all of the rooms. If you don’t mind a punk choker look, it works great! The sounds are muted, which is perfect.

10 out of 10
Very thick. Excellent quality. I’m using it for my isolation room/vocal room for recording bands and singers.The poor reviews on here are from people that don’t understand that this does not stop sound from entering or exiting a room. This stops reflections and echo in the room. Soundproofing comes from insulation in the walls ( Rockwool)

Effective at sound absorption — if you keep your expectations realistic
I understand that the seller would include the word “soundproof” in the product description because that is what people will likely search for in trying to find something like this. However, it is important to note that acoustic foam is really not a sound-proofing tool — rather, it is an acoustic treatment tool, meant to reduce reverberations and echoes (thereby improving the quality of audio in recordings, talking on the phone / on video chat, etc.). Granted, it does this by absorbing some of the sound (that is, if it is placed properly), but that is simply not going to lead to a zero-sound situation.With that in mind, this foam is effective when placed at first reflection points (in my case, in my home office, these points are particular locations along the side walls, ceiling, and on the wall behind the desk). The effect is a slight reduction in the amount of echo heard in the mic.But keep in mind that adding this sort of acoustic foam is merely one step that should be taken to effectively condition the sound quality of the room. This means additional cost, so it is great to be able to get acoustic foam at this price.Regarding installation, I used a glue gun and it made quick work of mounting the foam. Some advice, however, would be to mount the foam on panels of some kind (a plastic poster board, perhaps) and to then use removable/reusable wall-mount tabs to attach the panels to the wall. This way, if you decide to move your room around (or move your place of living), you can simply bring your foam with you.To summarize, understand what you’re ordering, research how to actually apply it, and you’ll find great value in this product.
