Ok, so for my pals studio which is already in a huge existing shell..

All walls will be:
2 inch air gap from wall
Stud frame with R30 insulation
5/8" drywall
1/2" drywall
Green Glue
5/8" drywall

Ceiling:
1/2 " drywall
Green Glue
5/8" drywall

wall between control room and studio:
a dual sided wall with
stud frame in middle
on each side of stuff frame:
2 pieces of 5/8" drywall sandwiched with Green Glue

Between walls and floow will be some kind of neoprene or acoustic sealant

Floor: Neoprene U Boats will float a frame above which will be 3/4" plywood, followed by 3/4" MDF.

How does this sound? What would you change?

I would think you would want 2 single sided walls with an air gap between control room and studio for decoupling them.

If you absolutely CAN'T do a double wall between the LR and CR, at least do a staggered stud wall (i.e., 2x6 sole and top plates, with 2x4 studs on 24" centers ON EACH SIDE. In other words, one side will be 24" OC and the other "side" will also be 24" OC but offset from the other side by 12". Search this site and you'll find pictures that explain this better.

Very cool. We can easily do the two separate air gapped walls. So my question is, how many layers of drywall on each wall? If I'm going to have an airgap, I'd assume two layers on each would be fine?

And now in each of these walls we would have a laminated glass? So would we have to make a window frame that connects the two walls? any info on the window panes? Thanks

How does everything else sound?

Steven,
I'd say 2 layers of drywall per wall is fine.
Yes you would have to have 2 panes of glass , one for each wall. You would want to have 2 seperate window frames that dont touch, otherwise they would flank sound through the frames. There are may threads on window building that explane it much better than me.
