6 Pack 1.5"X12"X12" Acoustic Foam, Sound Proof Egg Crate Foam(Most Soundproofing Design), Upgraded Acoustic Panels, Fire-Retardent Sound Proof Foam Panels for Walls, Doors, Sound Foam Made by WVOVW

This is our 2nd order. Use it to block out lights from coming in from the vent and work as expected.

My kids use these behind their computers to dampen the sound of their lively conversations with on-line friends. It does seem to help reduce the sound level from their rooms. I had ordered a different set about a year ago for my son and my daughter thought it would be a good iddea for her room as well. These are a little thinner and less dense foam than the other set I ordered. I think they still work though.

These are great when shipping delicate items

Great foam actually durable and washable

This sound mat is not dense enough to reduce any sound decibels. I tested with two different meters with the same results. These panels resulted in no reduction in decibels readings. They are extremely thin you can see through them at the low points. A thick pad of carpet would have a better effect.

Works perfect

These egg crate style acoustic panels are fine and will cover a small area with the 12 included pieces. There's no adhesive backing, so you'll need to use the included double sided tape for installation.Since it's just basic egg crate looking foam, I'm using these behind a photographic background to help reduce audio/noise issues in that area and because it won't be seen back there. Not that it's ugly, it's just plain old egg crate foam.I'd say the density of the foam is fair and overall these are fine for what they are.

Great sound dampening pads. Durable with a self adhesive backing, they are easy to put up. You can use these in most audio situations. Building a booth, the control room, a stream or studio room or just to stop the neighbors from complaining about the volume of your music. These are excellent and last a long time.
