Where is the scene? Sloped ceiling/ shoebox / flat floor-Acoustics Forum-Acoustic Fields Forum

Hello,

I am planning a choir kids concert in a shoebox room (rectangular) with flat floor and 30degrees sloped ceiling .

Sort of like that / ceiling
——– floor

Other detail, the back wall of high ceiling side is glass. the other side is cement.

I am wondering whever to place the choir on the lower ceiling side, or the higher ceiling side of the room.

Since the room hasn’t been used properly (sideways), it is hard to tell which way to go.
What we want is to limit the “noise” of public and clarify and amplify the musical production.

My instinct would be to place the ‘band ‘ in the lower ceiling part of the room. but I want confirmation.

Any opinions? advice?
