OT: Question on Lesson Studios

[jolly roger]

---------------------- multipart/alternative attachment

If you have forced air heating, acoustic ducting is available,  After 
building our studios, we soon found out that most of the inter studio noise 
problems, was coming from the ducting.
The ducting is a big concertina like hose, with insulation wrapped around 
it.   The outer and inner covering looks like a zinc impregnated fabric.

The walls were constructed with 2 X 6 framing, using steel studs off set on 
each side. Bat insulation was woven between the studs,Polystyrene was used 
for caulking around the framing.   two sheets of gyproc was applied on each 
side of the wall for rigidity.  We used a glass window through the wall 
into the common area.

The studios are practical so far as noise is concerned.   Are they sound 
proof? No.
But they are better than our University practice studios, and do not 
interfere with teaching operations.
  Pay close attention to the ceiling.  We took the walls to the ceiling of 
the structure, then installed a drop ceiling, with bat insulation above it.
