What are the acoustical benefits of raising the drums off the floor?

Drums are capable of putting out a large amount of energy & particularly a
lot of LF energy. Wood frame walls, floors & ceilings are (typically)
quite resonant. Masonry walls & floors, while not very resonant, are
pretty good conductors of sound waves & (usually) are solidly connected to
frame walls & ceilings at some point not too far away from the drums.

I've always operated on the assumption that uncontrolled resonances in the
recording environment are not a good thing. (The expert acousticians can
keep me honest here.) In a perfect world, you might have the walls &
ceiling isolated from the floor, a floating floor, or even a completely
isolated "Room within a room". But for a project studio in a pre-existing
structure, it's usually easier & cheaper to isolate the drums (or
amplifiers) instead of knocking down & rebuilding walls.

YMMV.

Thanks. I isolated my drums from the floor a while back to cut down on
the noise for my downstairs neighbor. I did it by putting a drum rise
on 4 car tire. - it took about 15 minutes. It worked well.

I did notice less resonance coming through the control room walls, but
I don't think it's made much of a difference on tape.
