Hi all - sorry if this is a stupid question - I've read through the USG manual and the SAE site, and I'm not sure I've come across the answer yet. I'm building a basement studio where the primary sound concern is isolation from the floor above. I'm under the impression that this means I want to ceiling to overlap the walls, right? (And this would mean constructing walls that come to about 1/4'' under the ceiling, topping them with neoprene/acoustic caulk, right?) Let me know if I'm confused about any of this.
So my question is - I'm dealing with a space with load bearing wall framing that already goes up to and is attached to the joists in the ceiling. How much isolation do I lose by having the walls, rather than the ceiling, overlap? (I'll be caulking everything with acoustic caulk). Is it a probem for sound transmission that the framing for the walls is already attached to the joists of the ceiling? I also have to build one new wall - should I attempt to build the ceiling over it first, or will this not matter so much if the other walls are already in place as mentioned above?
Thanks!
