I recently moved into a small room that will be used for compiling /
editing live recordings. I have no illusions of being able to turn a
14'(L) x 8'(W) x 8'(H) room into a great sounding space, but I want to
make a reasonable effort towards minimizing the worst of it's faults.

Having the room's width and ceiling height both equal 8FT is an
obvious problem, but I'm curious how the ceiling situation will affect
the expected resonant modes at 70hz. The 8FT ceiling measurement is
from the floor to the suspended ceiling; the "real" ceiling is another
two feet or so above the grid. (yeah, I'd love to rrip the suspended
ceiling out, but the landlord would shoot me; besides, the ceiling is
part of the air circulation system.)

Anyway, can anyone explain how sound reacts to the two ceilings? My
initial thought would be that higher frequencies would "see" the
suspended ceiling at 8FT, but low frequencies might ignore the 1/2"
tiles and "react" only with the strutural ceiling at 10FT (+/-). Does
this make any sense? If not, can someone explain the right answer?

Thanks.

Steve
