Advice needed: treatment plans
Posted: Sat Jun 18, 2005 3:12 am
I'm going to be having some electrical & lighting work done on my basement studio in the next month, so I will be clearing the room out, and I'm thinking I might as well seize the opportunity to do some acoustic treatment as well. I've spent a lot of time on the various forums (mostly here and studiotips) trying to soak up as much information as possible, but I still feel a bit at sea about specifics.
Attached is a JPEG of my floor plan. Mix position is at the top of the drawing. The back wall is pretty far away (about 20 feet).
Wall corner trapping in the mix area is tricky for two reasons: (1) access door in the left corner (it's about 56" high, with 27" free wall above); (2) "bay window" alcove resulting in about a 130-degree corner on the right. The side wall on the right is very rough stone foundation, so it's problematic to attach anything to it.
What I'm thinking right now is something like this:
1) some kind of broadband absorption along the wall-ceiling corners at the left and front of the mix position--I'm thinking either "Superchunks" or just wrapped 4" 703 panels installed across the corners, if I can figure out how to attach them. (Ethan's new SoffitTraps might be ideal, but they're beyond my budget.)
2) some mid-to-high absorption along the walls and ceiling around the mix position--either more wrapped 703, or 2" foam.
3) either some absorption or diffusion above the drum area. I want to be able to get a better sound with overhead mics, which is of course a problem with the low ceiling. Would absorption or diffusion help me more here? (BTW, the floors are cement, mostly but not entirely covered by rugs. I know wood floors are recommended, but that's a change that's beyond the scope of what I can do rigtht now.)
One general question about using rigid fiberglass panels across corners: does it matter whether the edges form a tight seal with the walls and/or ceiling? I ask because I could probably lay a few 703 panels across the obtuse wall corners in the alcove area to the right of the mix position, but obviously it would be impossible to get the edges of the panels to sit flush to the rough stone wall. The panels would just kind of be sitting there leaning against the corners. Would this be any use?
Many many thanks for your help & advice, everybody...
