Circular Recital Hall Design Considering Source Directivity
The 256-seat Carrie Chang Music Hall is a remodeled lecture hall having a generally circular plan, 21.6 m in diameter. The room acoustics design focused on providing early reflections to compensate for high-frequency loss at the seats away from the direction of the sound source. This was realized by introducing convex curved walls on the stage and side boxes on the audience floor. Removing the original ceiling to increase the volume yielded a 1.02-s midfrequency early decay time (EDT). Evaluation of the overall impression with a tenor singing and a cello playing showed little difference among the seats with a 120° variation in viewing angle.
