Control Room Size

Archived from groups: rec.audio.pro (More info?)

Your room size is not excellent...

I suggest you to buy any book from Alton Everest....

The best $19.77 item you can buy is you are bulding a studio!!!

And of course, what Frederico says!!!

$20... You spend more than that on café mocha and pizza every day!

Look at the ratios of your room dimensions:

L: 12.5' = 150"
W: 11.5' = 138"
H: 10.8' = 129.6"

L:H = 150/129.6 = 1.16
W:H = 138/129.6 = 1.06

These dimensions make your room reasonably close to a cube - which from
an acoustic point of view, is a very bad.

This will mean you have room modes bunching up together to produce
boominess at the resonant frequencies of your room dimensions

> Is there a problem with the size of the control room?

As it stands, I would say yes. You need to change one dimension to move
the room's dimension as far away from a cube as possible.

Personally, I think dropping the ceiling would help (but then I haven't
seen your situation)

Yes, or the ceiling height - which ever is more convenient

As has already been suggested, get F.Alton Everest's book "The Master
Handbook of Acoustics"

Also, take a look at my Control Room Calculator spreadsheet. You can
download this from here http://www.whealy.com/acoustics/ControlRoom.html

Enter the room ratios that I calculated above into the sheet "Room
Ratios", and then enter the room's width on the "Initial Values" sheet.
Then you can play around with different surfaces for the walls, floor
and ceiling and see how it changes the room's reverberation time.

Please read the instructions on the download page carefully in order to
learn how to use the spreadsheet. Please also read Everest's book,
because this will explain the concepts and terminology of acoustics.
