Long control room: 11' x 23'
 
Greetings, everyone!

My finished basement room is a long rectangle, 11' x 23'. The walls are sheetrock, and floor is carpeted, and the ceiling is a rather low drop ceiling at a little over 7'.

I'm looking to make it into a control room for accurate mixing, and possibly overdubbing later on. (I'll eventually construct a separate tracking room in my two-car garage.) I'm aware of the general bass trapping and sound absoption issues that I'll be dealing with, but I'm wondering if those issues are made better or worse by the length of this room.

I need to decide whether to try to use the whole room, or to use the space in one end to construct an iso booth for vocals and guitar. I imagine that I could still treat the room as effectively if I used something like 1/3 of it to put the iso booth in.

BTW, the doorway into the room is midway along one of the 23' walls. Also, there's another 16" - 18" available above the drop ceiling, if I remove it.

Has anyone ever dealt with a room shaped like this?

my CR is not too different to yours other than the height. 20.5' x 13'. The real difference comes in with the height, 9.5'.

The link below is to a post by the Eric Desart, he of great acoustic knowledge and awesome friendliness and help.

Acoustics :: View topic - ROOM RATIOS: M.M. LOUDEN ANALYSIS

Using the information on that page, it looks like reducing the length of the room to 15', (14.98' to be exact, although 15.4' would be an option too) could produce some favourable results, if you leave your height at 7' and reduce the width to 10.5'.

In the post you'll notice a section called: "Some best ratios". The dimensions above were calculated using the "Flat Room" option.

One great thing about having a drop ceiling is that you can just stick rockwool above the panels!

You might benefit from shortening the room a few feet, but I wouldn't necessarily use the extra space for a booth. I'm not a fan of booths because they sound small and boxy unless you fill them with a lot of treatment.

Well that changes everything. A room's dimensions are to the rigid boundaries, and a drop ceiling is not rigid. My best suggestion is to use my ModeCalc program:

RealTraps - ModeCalc

The description on the above page explains all of this in detail. If you post your room's exact dimensions, and to the rigid floor above for the height, I'll be better able to suggest what to do next.

my bad. i didn't read the whole post

Ethan's right, it is to rigid boundaries.

Thanks, guys, for the helpful replies. I'll re-measure to the floor above the drop ceiling and post those dimensions soon. Maybe I'll forgo the booth, and go ahead and convert the garage into a large live tracking room for drums (and vox, and everything else).
