FYI (no question, discussion maybe)
Something I learned today from one of the USG articles: If you have two rooms you should not build a partitian wall on a shared floating floor, because noise flanks through the floating floor.
Better is to have the partitan wall to the real floor, and a floating floor within each room (walls are not on the floating floor).
Better still is to build two isolated rooms, each with their own floating floor.

I was about to ask that question, thanks for posting z60611. I have a 17' X 12' concrete slab building in my backyard that I want to turn into a studio. My plan is to split the room in half and sound proof one room. I am thinking of using the staggard stud design. I will also install a floating floor.
"But by having the wall on the floor you're lowering the resonant frequency of it?" - Right - which is also part of why Bob's comment about separate walls floated on separate floors being best is true... Steve
