need advice on taming a very "live" room!-Acoustics Forum-Acoustic Fields Forum

I need some advice on acoustic treatment of a room. This will be a general purpose room for an arts ministry, so will be similar to a church application. Classroom, small music groups, Bible study, workshop etc. Right now, a clap test shows excessive ringing! Amplification for speech and music will be used as needed. Since this is a multi purpose room, setup will be flexible.

The room is about 15 feet high, 20 feet wide, and 30 feet long. Walls are concrete block, floor is concrete, and the ceiling is unfinished metal joists. It is in a commercial, rented space.

I am currently planning for 16 sound absorption panels that are 3 feet by 6 feet and that use Owens Corning 703 fiberglass insulation panels. I plan to space them evenly around the walls with the tops of the panels at the eight foot mark.

Will I likely need more panel? Will I need to mount some panels higher in the walls?

This will not necessarily be a room for audiophiles. I just need to make it more useable.

Thanks for any advice you can give!
