While Philadelphia’s Kimmel Center (with acoustics designed by Artec Consultants) is designed with customizable acoustic panels and walls, the two concert halls in the Rome Auditorium were created for classical music. There is a third theater that can transform in size, but the acoustic engineers at Muller-BBM maintain that a more versatile space will sacrifice reverberation. So they made the compromise of designing the larger halls for symphony orchestras. However, “the largest hall exceeds the theoretical limit of a naturally acoustic hall.” They built a scale model to determine how sound would track inside it and are hoping that the curved ceiling will funnel the sound appropriately.
