Aurica Pyramid Sound Proofing Acoustic Foam Panel 10"x10"x2" - Single

You can try this not bad product

These work well if the points of reflection of sound are identified correctly in the roo. Nevertheless, the overall acoustics and dampening around the room need to be well understood in order for these to work efficiently. Having glued 8 of these onto the walls ( room = 10 x 9 ), they have reduced the overall echo and reverb. The sound levels outside the room are remarkably low, not disturbing anyone around. Wish these came with adhesive back panels - however, not a major downer as double sided tape and Velcro on 4 corners of each worked just fine. A combination of large and small panels will work the best.

It didn't make a lot of difference I purchase a bunch of them if I recall about 10 it did not reduce the echo problem that much, later to solve the echo I just used heavy curtains that worked a lot better and is cheaper and the room also looks better.

Good but higher Price

For its rate the size of the foams are very less....if big it will be correct..

Great product....will buy some more of these.This is the best quality by far.. I have ordered online.

Didn't quite find a reduction in sound

works like a charm
