New Live Room / Ceiling Treatment

[K. Osborne]

This is one that's totally subjective to opinion, but I'm open to all thoughts.

I've got a new live room with wonderful wood floors that I'm in the process of treating. It's 13x15x10 (at the center plateau), and the ceiling slopes upward in the center--it's sort of "gem-shaped"--like this:



Already treated the walls with spaced OC705 (2" thick) absorbers (3 on each wall), and two of the corners with bass traps (4")--the remaining corners are untreated--one has the door to the room and the other has a bookshelf that is built into the wall (can't really fix that?)

What do you suggest I add next? I was thinking about treating the ceiling so that I get a better sound for drums, but I'm not sure where to start---where do I put the traps? 2" or 4"? Should they go vertically or horizontally on the ceiling?

Any suggestions would be great.

I would start to treat the upper ceiling to wall corners next.

So put 2" or 4" panels (which one?) diagonally across where the walls meet the ceiling? I hope I understood that right.

What after that? Any other suggestions?

For straddling corners use 4" or thicker. What I mean is the following. See the upper panel covering the where the ceiling and wall meet.

Gotcha.

I did some tests and some math and figured out that my room's Y dimension (floor to ceiling) has a peak at 55Hz, or A. If I sing 220 or 440Hz, I can HEAR a ring at A. What can I do to prevent this?

You could put some 4" panels up there spaced off the ceiling a few inches.

I'm guessing about center-ceiling would be the best spot for them?

Hard to say but maybe where the peak is.
