resilient channels vs. framed out ceiling

Hello out there!

I have a question.

According to the architect drawing up my studio plans, it seems that I
have a slightly strange roof on my garage that doesn't lend itself
easily to soundproofing. The ceiling has four sides pitched up to a
point in the middle. This shape and stucture apparently makes it
somewhat challenging to build an secondary inner ceiling supported by a
secondary inner set of walls. We have discussed using resilient channels
to attach the ceiling drywall to the roof instead of attaching the
drywall to a new framed out inner ceiling.

Does anyone have any thoughts on using resilient channels to attach the
dry wall to the roof vs. the framing out of an inner ceiling for the
drywall? I could try to borrow a digital camera this weekend if that
would make analyzing this easier.

Thanks,
David

A secondary inner ceiling is always the better way to go if possible. If
you have any problems with jet noise it is the only way to go. If you are
more concerned with sound leaving the studio. You can get away with RC. How
much sound proofing do you need? A few pictures would help, email them to
me dan@s... and I will compress them and post them on the site,
so people on the list with modems don't get a 2 meg list email.
I will set up a ftp area on the site so we can exchange pictures and cad
drawings for discussion on the list. CAD drawings I will try to convert to
a pdf so everyone can view them.

I am more concerned with sound leaking out. When drums get into the
act... everything gets kinda loud.

Thanks,

P.S. I am against having attachments. Large unwanted downloads and
viruses are my concerns.

Since the sound going through the ceiling tends to propagate up you can get
away with RC, If you do, I would put up a few layers of drywall before
installing the RC and the 2 layers of drywall. RC is only rated to support two
layers of 5/8 drywall. However you might have a problem at the wall-ceiling
joint and it might reduce the the effectiveness of the floating walls. Since the
wall will now have two points of contact with the outer structure even if they
are both designed to decouple. I would build it as soundproof as you can
afford. I've never heard anyone complain their studio was too soundproof, most
wish they had done a little more.
Have you had any luck finding a contractor? If you can't find a studio
contractor, you might look framers and drywallers that do major commercial
building (not just light tenant improvements) they should have experience
framing odd angles, curves, soffits, ect.
