I have a rather square live room 9’6” high, 24’6” long, 18’6” wide and I was considering raising the ceiling. My airbarrier walls (2 of them and the original wall) extend to 9'6". If I was to take out the false ceiling and put in a dry wall ceiling I would want to have the walls meet my air barrier walls at the 9'6" mark and then extend upwards to create a seal. The only design I could think of to do this would be a pan style ceiling. I have an additional 10 feet above my false ceiling to extend. Would a pan style ceiling create problems with reflections?

Wow, I'd love to have that much available height!

I have to admit I'm not much of a contruction expert, so I'm not sure what a pan ceiling is. If you can describe it a little more, I'll do my best to help.

This kind of arch.

Pat,

I assume the forum software took out the spaces in your drawing, but the word "arch" explains it.

In general, arches and concave shapes are bad acoustically because they focus sound toward a single point. Such focusing is the opposite of diffusion. An inward curve can be acceptable in a studio or control room, but only if it is covered completely with absorbent material.

If I misunderstood your proposed ceiling shape and addressed the wrong point please let me know!

Go for the height! You'll be glad you did.
