This is a really cool hobby. I'd be interested to see pictures too, once you get going.

Air-tight is sound-tight. If air can escape, sound can escape. So, every sound-proofing solution will include tubes and tubes of caulk applied to every seam.

Sheetrock walls on 2x4 frames are perfect sound-transmitting membranes. Sound frequencies applied to one side will be vibrated off the other side much in the same way as a speaker cone.

The construction of a sound-proof wall that I think would work best is to frame the wall on a 2x12, with supporting studs staggered from one side to the other, so no direct sound bridge passes from one membrane to the other.

The other way to prevent sound from being transmitted by the wall itself is to lower the resonant frequency of the wall to below the audible human hearing range. You can purchase expensive sheets of lead-impregnated vinyl for this purpose.
