DESIGN

I should mention that my wife is an architect and everything in this section pertains to the design and wall assembly.  For those who care about the nitty gritty, we decided on using two layers of 3/4" drywall with a layer of green glue in between, and this mounted on a resilient channel.  This, hypothetically, would decouple the walls from the frame and should stop the transmission of low frequency through the walls.
