Optimum ceiling design in small control rool?

I'm building an additional small control room (13'w x 15' deep). I have about 10' of workable ceiling height. Could someone show me a sideview (cutaway) of a good design for the ceiling. Thanks! Phil Hadaway

Try this. Designed for 5.1, which will be the the standard shortly.

That's very helpful. Should the ceiling above the reflective and open areas be at an angle to the floor? How hard of a reflective surface are we taling about? Sheetrock or wood? I'm assuming the open areas are filled with rigid fiberglass and covers are made from wood and cloth? If my structural ceiling is at 10', where should the "dropped" ceiling start and end at? (height). I'm not using soffit mounted monitors, going with nearfields for this room. It's primarily a voice over, ADR control room with a VO booth in front. Thanks again for all of the help.

I don't understand the question. The only part that has to angled is the reflective surface. You can make the absorbent area parallel or angled. The upper ceiling is the current one. Make a copy of the drawing and mark it up to show what you mean.

Either will work. It is not critical. The more massive it is to reflect lows in a similar fashion, the better.

The question is vague. The drawing is done to scale. The back absorbent area is 9' high if that helps answer your question.

Not critical. The speaker location is for determining the locations of the speakers, reflective surface angles and listening position. Andre
