2 Pack pyramid Acoustic Foam Panels, 48 x 24 x 2" Sound Absorbing Panels High Density Studio Wedge Tiles Fire Resistant Acoustic Panels for Home,Office, Recording Room, Studio (2Pack, Black)

Bought eight of these and they all came the same size and they were pretty thick. Haven't put it up yet, but satisfied so far with what I received.

I was skeptical how well they would form back after vacuum sealed. Just plan on giving them some needed time after unpacking to form back to original shape.

Actually I though was coming with sticky part, but no. Now I have to buy glue to attach these 2 panels.

This product suited my means for dumbing down excessive Noise over a Door cutting to Fit keep in mind it expands up to when unpacking.

Between two orders, all 8 panels were different sizes. I have quite a bit of experience with acoustic panels and was skeptical about ordering this style as this many small squares make it very obvious when the quality control is subpar. That is unfortunately the case with these - even after fully expanding, the sides are uneven and the length/width are completely inconsistent. I was able to mostly make them work, but I'll be replacing them eventually.

Used as bass drum muffling and am very impressed by it.

The adhesive works great if you are going to permanently install these. If you need to take them down to move or do something else , this adhesive sticker can be easily removed, you need to stretch the adhesive sticker and tear it off without damaging the wall.

Excellent noise reduction and very easy to apply with double sided tape. Definitely great value for money.
