All-
I have sent Dan a few quick drawings (gifs) to upload to the site today as I
am curious for comments that anyone may have. I began describing my
scenario in part yesterday. This is a garage special. The structure is
wood framed, wood sided. I closed off the garage door through framing and
two layers of 3/4 plywood on the exterior. Inside I constructed a metal
stud frame completely detached (2" gap) from the existing structure using
roofing rubber as an isolation barrier between the walls and the floor. 6
inches of insulation went in and then the first layer of 5/8" gypsum. I
then used resilient channel and put up another layer of 5/8" on the walls
and 3/8" on the ceiling. The middle wall has rc on both sides and two
layers of 5/8" on the tracking side and one on the control room. The
original rafters (4) in the building spanned the width at the wall height of
9'. I removed these and put in a total of 10 doubled ties at a height of
ten and a half feet. My plans are to then attach either plywood or masonite
to the bottom of the ties with the cavity lined with 4" of 703 for a panel
resonator. I have some airplane noise to deal with and I think this will
further help as most of the noise is already reduced (thanks to Dan for some
tips on this in a r.a.p. thread). I also feel this will help against
boominess in the room due to it's limited dimensions. Finally, I will have
a polycylindrical diffuser behind the mix position and two bass traps
(rolled fiberglass in wire construction) in the two corners of the tracking
room. A wood floor will also be installed. I understand the dimensions are
no where near optimal but it's what I had to deal with. I have not yet
completed construction yet so I have not yet determined what other
acoustical treatment will be needed. Sorry for the lengthy post but I
admire the knowledge found in this group and welcome any comments.
