Hello All

My name is John. I am looking for suggestions on acoustic treatment of the new
studio I am building. This is my second studio, but the first one was pretty
small (two small rooms in a basement) so the acoustic treatment was pretty
easy. (all I did make the space dead) The new studio is in a detached garage,
wooden framed with vinyl siding. I am building rooms within this structure
framed with metal, insulated, covered in black fiberboard, and then finished
with sheetrock. The ceilings are 10 ft, so I am going to put up a dropped
acoustic tile ceiling about 6 inches below the seetrock ceiling. The floor in
the control room will be wood parquet, and the studio will be carpet. (I have
uploaded to the studiotips site a image of the layout) The 8x8 drum booth is
still a maybe. When I get all of the framing up I'll be able to better judge if
it is too small or not. With all of this sheetrock I'll surely need treatment,
but how much? I was thinking maybe a diffusor on the back wall of the control
room, and foam lining the front walls stopping at the console. This is merely a
s.w.a.g. so I am open to suggestions. As for the studio I don't even have a
guess.

Thanks in advance,

John P. Sexton

John's drawing is in the file area. I have switched the order of the
drawings in the area so that the latest ones are at the top of the list.
Can we get photos of these rooms when you guy's have finished building them?
I have also added an acrobat pdf of Dave Martin's room in case people
can't view a word doc, the file is about half the size as well. Dave,
let me know when there is new one.
If any of you like to post drawings but you can't convert them into
something everyone can view let me know I may be able to convert it. If
you only have paper drawings you could send to me via mail and I could
scan them.

John, in the file area there are a few rt60 calculators download one
that you can use. There is also a list of absorption coefficients in the
file area. With the rt60 calculator you can estimate the amount of
absorption at six frequencies. The basic goal is to get all the
frequencies to have about the same amount of absorption. So you enter
the amount of area of a material (i.e.: drywall, glass, carpet, et) and
their coefficients. Then pick some of the absorption materials (many of
us prefer a 703 type fiberglass panel for most of the room) you want to
use and start adjusting the amounts until the absorption at the six
frequencies is roughly equal. Now you will know about how much
absorption material you need to add.
Placement will be your next problem and there is a page on the
studiotips site about placement. In the control room I generally make
the monitor wall dead with 703, kill any reflections off the side walls
and ceiling with some type of foam or 703, and mount diffusers on the
back wall. In the recording room I try to have balanced absorption but
fairly live with lots of diffusion. ISO booths are tough try anything,
some diffusers may help. ISO's are so small they tend to go very dead easily.
If you don't already have The Master Handbook of Acoustics by F. Alton
Everest you may want to pick it up it goes into alot of this in more
detail, there is link on the studiotips site under book reviews to buy
it from Amazon it costs about $20 -$25 and its worth about $2000

I'll do it; I loaded Corel, into this computer, which seems to be a good
program for experimenting with building sizes. The Contractor is supposed to
be out this week to give me cost estimates; that will tell me how much I can
realistically build.

Thanks!

Run some calcs on RTC and set a target.

If you don't have Everest's Master Handbook, then buy it. It will help you
ask better questions.
