Prpixel,
I was wondering what you meant by "Carpeted floor that "floats" (room is located above the garage)" . . .
I have a similar room that I am converting to a sound room. How did you do the floating? I am thinking of taking some resilient foam roll stock (used for hardwood floors), putting it on top of my existing plywood, then putting a second layer of plywood on top. Is this similar to your setup?
thanks, Bill
