For the walls of a recording studio,
what do you think about this setup:
Concrete Hollow Block Wall (outer wall)
+
6-inch space
+
Another Concrete Hollow Block Wall (inner wall)
is this soundproof?

Jan 08, 2008 02:04 am Like Gregor said, you'll need some kind of material to fill the walls with, though 2 of them may be overkill. One filled with a medium to high density expanding foam, like the kind you find in a can, should be pretty darn soundproof, so long as you still plan on insulating and erecting interior walls. Then all you've got to worry about is the studio entrance and the floor and ceiling, lol.

should i fill the 6-inch gap with something?
Jan 08, 2008 10:21 am I think it'll be soundproof. Air is a great deadener.
I wouldn't worry about the space in between. Leave it air.
You would have to worry about the doors/windows & ceiling though.
Jan 08, 2008 11:42 am Are you thinking of building this or do the walls already exist? If you are building, *personally* I would build wood framed walls sheeted with QuietRock (sound proof drywall). A room within a room. Air space AND detachment is the key. You haven't mentioned anything about the ceiling which of course would not be cinder block. In my opinion there is only ONE way to build a soundproof room. Experimenting will almost always fail. Don't try to re-invent the wheel.
Another consideration is that a soundproof room is a air tight room. You will need to consider ventilation.
In summary: it is a very expensive project and I highly recommend it be built using proven methods. It is not the time to experiment.
