I have been told using Drywall brand acoustical caulk between studs and
sheathing (drywall) yields same result as using rc channel as it
reduces sound transfer from drywall to studs. Does anyone have
experience with this. If it is true, it seems a lot easier than
installing staggered studs and rc channel.

Oh yeah, is this the stuf to caulk seams with, or should I just use
silconized latex 30 year caulking.

This is definitely NOT true. The chalk is used to make to room airtight it would
be used in conjunction with the RC channel, double wall or anything else. Use it
to chalk the seams the wall to ceiling joint and the wall to floor joint. It
would be the best chalk to use since it designed to remain flexible for many
years and allow the RC to work properly. It should be the cheapest chalk to use
as well it take many many cases of chalk to build a studio. When in doubt chalk
it.

Then sneak up on it .... and caulk it some more.

If your handle squeezing hand doesn't ache at the end of the day .. you are
doing it wrong. 32 square feet of wall (one 4'x8' sheet of drywall) with a
1/4" gap around the edges, uncaulked, is the same as leaving an 8"x8" hole in
the wall. Add up all the edges around all of the sheets of drywall in the
room and you don't have to miss very much to leave a pretty big hole
acoustically.

Sorry. What is chalk? Is it powdered chalk, or some type of special
caulking? If powder, how does it stay in place? Sorry for ignorance.
