Case studies of variable acoustic design: A repertory theater and performing arts chapel.

Two multipurpose halls required variable acoustic design with minimal alteration of their appearance. The 400‐seat Performing Arts Chapel at Fuller Theological Seminary (awaiting construction) will accommodate everything from pipe organ concerts to lectures‐in‐the‐round by employing multiple variable acoustics methods with adjustable treatments deployed above the visual ceiling and along sidewalls and the performance platform. The 550‐seat Virginia Piper Theater at the Mesa Arts Center (recently opened) successfully hosts everything from drama to choral works via novel, inexpensive, and wonderfully simple means, entirely beyond audience view.
