John, others:
I am about to install the new control room floor and have a question:
I have decided to float two layers of plywood (5/8" and 3/8", glued and screwed) on top of fairly stiff, sponge rubber discs (about 3" diameter, 1" thick, spaced evenly throughout the room) and wonder if I need to fill the remaining cavity (only about 3/4" when disc is compressed) which will be left under the floor, between the existing concrete and bottom of this "subfloor"? I am not concerned about isolation, as this is a basement install, I just wonder if this airspace would create "resonation" problems, or is this too "thin" to worry about. The sub-floor will be covered with 1" pine planks, and of course, I will lay a vapour barrier on the concrete to begin. FWIW, the room is 12' X 16', with 10' ceilings, all corners 45 degrees (walls and ceilings) with base traps "built-in" to all corners (again, walls and ceilings).
Obviously, I don't want to find problems later and have to rip out the floor, but if I can save $ at this stage, I'd love to hear it...I'm "way" over budget.
I also thought of putting carpet underlay in between the vapour barrier and sub-floor, with the discs on top of this, thereby "deadening" and resonation...any thoughts on this as well, or is it all overkill, once again?
Thanks in advance for any all suggestions,
