Sound Proofing Panels 24 Pack Egg Crate Acoustic Foam 12 x 12 x 1.18 Inches High Density Acoustic Foam Panels Flame Retardant Sound Absorbing Panels Studio Treatment

I used this to pad out the interior of a flight case and it didn't disappoint. You get a load of square sheets in the pack, although I was concerned with the size of the pack, but no worries they come vacuum packed!

Makes less difference than I hoped but customer service was great and helped to resolve my issues.

They didn’t stick to the wall for me I bought over a €100 worth for Xmas my sons also got autism and needs a laptop all the time we tried to sound proof his room and they would not stay on wall check

Completely waste of money. Amazon should look into it, because this is a scam. Those panels have no soundproofing effect whatsoever. They are selling this hoping they will get away with it. This is just cheap regular foam, cut in a funny shape. The thickness and the density of the foam are not as described on the website.

Not really the thickness I expected.

It is good quality foam and a great price. A perfect addiction to dampen acoustics.

I bought 2 packs and lost 4 tiles overall due to poor production, they were overheated or something as when opened the stayed flat and brittle unlike all others that expanded easily.

This product is just shaped foam. It's not very easily applicable and doesn't stick on firmly. I used double sided tape which was quite sticky but the low density of this foam meant that there wasn't much contact area for the panels to stick strongly. Maybe adhesive spray would be better but I didn't try it.Soundproofing wise, I used it inside a cabinet housing noisy equipment but I didn't find it to be very effective. I could still hear the equipment after lining all the inside of the cabinet with this. After spending the money and time to apply it, I wonder if regular flat foam would be more effective...
