Soundproof

[Farview]

I have a bunch of these in the back of my control room. The hardboard is 1/4 plywood. It vibrates and the sealed chamberwith the insulation absorbs it.

I was talking about the foam(mattres)
And studios use wood and extra drywall is supposed to help there both solids.
One of the links I went to had curved plywood on the walls.
Im not sure but I think it about reflecting a normal flat wall will bounce the sound back and forth.
Anyone in ct know where to get rigid fiberglass?
Im going to check hoke depot and lowes.

Probably falling on deaf ears again... but as was said about that is used either for sound proofing (to keep the neighbors from calling the cops) or for diffusion. I talked about diffsion and absorption above. Read the link I posted... it explains all of this in detail with pictures....

Here's the link again.... http://www.ethanwiner.com/acoustics.html

Read it someday and you won't have to ask these questions. You might even find out that the guy who wrote the article lives in CT and tells you exactly where to buy the stuff in this link http://www.musicplayer.com/ubb/ultimatebb.php?/ubb/get_topic/f/26/t/001246.html . I already told you you will not likely find it at a regular hardware store like Lowes and Home Depot. Is this thing on? I'm giving the answers to the quiz here.
