In Reply to: Duct board vs Owens and behind the wall bass traps posted by Scholl on February 9, 2004 at 03:40:15:
If the duct board is what I think it is, then, no, it will not do much for absorbing anything.Thin wall panels can only help with the mids and highs, and the thinnest I would recommend would be the 3 1/2" fiberglass on the 1X2s. Add some semi-rigid fiberglas on the back (some 705) for a bit more LF absorption, but this adds another 1" to the panel thickness.
Idealy, any sound absorbing panel should be spaced out from the wall, this improves it's LF absorption, but you could flush mount if absolutely necessary.
Just remember that too much absorption of the mids and highs, without corresponding absorption of the lows, can unbalance a room toanlly, and make it sound boomy.
Yes, bass traps could be placed "behind" the walls, as long as they were properly constructed and sealed, etc. This would only lend it self to square/rectangular based traps, such as Ethan W. recommends.
Fiberglass behind the drywall is not doing that much to absorb sound, perhaps some in the bass, but virtually nothing in the mids and highs.
