Sound proofing

Love these threads here. Just love the extra learning that I get... they actually make putties now for the job... great...
as the one studio guy said... basically fire wall rules... but have done it all sorts of ways... biggest thing is, by building second wall not tied to first, you have air space to help deaden and you have the extra wallboard. Again, double the board, increase the noise blocked.. trick also works on busy roads... amazing how happy your customer is just by putting an extra layer or two of wall board on their walls...
learned from experience... styrofoam board actually increases the amount of transmitted noise. Now there are warnings about it reacting with nm wire as well...
anyway... listening for more hints as have three people in Jamaica talking about studios in their new homes.. their architect is a friend and bugging me about ideas for wires and such for the mikes, boards, etc...

My studio is really more of a rehearsal space in a converted garage, though I do a bit of recording out there. We had the house built, so I specified double rocking of the common walls between the garage and the rest of the house. I had HVAC ductwork run out there and the space above the garage ceiling is insulated. I put up an exterior wall over the garage door stuffed with thermal/acoustic insulation, and when the old central HVAC wore out I replaced it with two smaller units with one exclusively feeding the studio.

It works for me.
