hey guys. i'm new to this forum. I'm a drummer from israel and i am just about to build an acoustic training room for my and my band. okay so i don't know much about acouscits so i thought i should ask the pro's ! I got recently a room that is about 200 square meters, and i want to close a little corner with some drywalls. my first Q : is drywalls good from acoustic's ? anyway the corner that i choose to do the room is rounded. is it good or bad ? i want to make a room that one dry wall is about 3-5 meter (depend on which is better) and the second one would be 3-4 meter . and the ceiling is 2.2 M. and the rounded wall is concrete. so here's a sketch included. looking forward to your early responses. shoval.
