Assuming your fairly typical suspended floor construction consisting of carpet over pad over subfloor (3/4" plywood?) over floor joists over open crawlspace or basement... at which frequency will sound start to pass through the floor?
I'm curious because I'd eventually like to move as many of the electronic components to the crawlspace under my listening (family) room as possible, ideally leaving nothing but the speakers in the room itself. The primary intent is to declutter the room, but I thought I'd gain some isolation from the move as well, especially since the gear will be effectively sitting on dirt and thus isolated from all structure borne vibrations.
And before someone asks, this crawlspace isn't a ratty hole likely to fill my gear with dirt and critters!
The space has vinyl faced insulation on the concrete walls, 20mil vapor barrier laid over the dirt and sealed against the walls, has the former vents to the outside sealed, and is open to conditioned air from the basement, so this is a pretty benign environment and has fairly easy access to boot. (And the rim joists will be sealed air-tight with additional insulation before any move occurs.)
Thanks!
