- Additional Information
calling these "acoustic panels" is a joke, but not a funny one. so thin you can see light through it. a couple of bucks worth of cheap foam cut to mimic the appearance of actual acoustic panels.
Thin foam like this does nothing to soundproof any space. If you want real sound proofing (or music/narration studio sound dampening) you need rock wool. HD will order it for you (Roxul Safe n Sound) and you just have to hammer together some 1x4 frames for it, cover it with cheap fabric, and hang it on the wall. Foam, unless it's like 12 inches thick, does nothing for sound dampening other than look somewhat nice as a pattern.
deadening/proofing not interchangeable terms
I purchased these to reduce noise and improve acoustics in my classroom which has a concrete floor and all hard surfaces after my ceiling panels were inexplicably switched from aucoustic tile to flat, thus turning a pleasant classroom into one where you can't hear clearly so everybody talks louder and louder. Exhausting. For a kid with hearing impairment at all, it is impossible to function. Sound proofing means sound is prevented from passing through a surface or material. These panels are not intended for that purpose. Four stars because I can see no reason for them to be so expensive.
Exactly what I was looking for.
