Float room on Rockwool

After reading many threads about floating a floor on OC 703 (Rod, Ethan, etc), I had the idea to float an entire room on OC 703 or Rockwool. I did not find any specific info on the web. Could anybody tell me if this is possible? I intend to : 1) lay rockwool on floor 2) lay 2 layers of plywood 3) buill wall frames and ceiling frame resting on the plywood 4) drywall, greenglue, etc. Would that be a possibility?

If possible, you can delete this thread. I got some answers on Gearslutz. Probably the same guys that hang out here... Thanks

Here's another thread that someone linked to just today: http://www.soundonsound.com/forum/showf ... t=1#126863 Good advice from Eric and Paul... - Stuart -

Thanks Stuart, good info in that thread. Here is my situation: Building of rehearsal rooms. Need decent isolation but not perfect. Most bands don't expect to have perfect isolation at bass frequencies. I am building on 2nd floor of commercial building. My neighbors are not going to be that fussy about sound because they themselves generate a lot of noise. There is a concrete slab on floor, ceiling, and walls are all concrete. I would build the walls directly on the concrete slab and the ceiling floating on the walls. I just need a solution for the floor to reduce impact noise for the neighbors down there and for preventing flanking from room to room. What do you guys think?

Probably a drum riser for the drum kit, plus individual isolation pads for amps and things. That should take care of the impact noise. But you should do some tests first, to see how bad it is for the neighbors downstairs: set up a a drum kit in the room as it is right now, and get the heaviest, loudest drummer you can find to bash away as hard as he can, while you check the levels in your room, the room next door, and in the room underneath, using a sound level meter. That will tell you how bad the problem is, and based on that you can design the right treatment. You could even simulate a drum riser with some thick 703 and a thick sheet of plywood, to see what difference it makes. But you do need those real numbers to give you real answers. So beg, borrow or by a sound level meter, and take the readings. - Stuart -
