This facility provides accommodations for concerts/productions from community groups, broadway shows, and other professional performance entities, such as the New York Philharmonic that performed for the gala opening weekend, in addition to showcasing performances from the university’s music ensembles and theatre/dance department.

The Performance Hall boasts flexibility to best suit the acoustical characteristics of the hall to the performance type since the wide variety of programs have differing acoustical needs. Natural room acoustics support for symphonic, choral, chamber ensembles, and soloists that desire supportive room reverberation is provided by massive and tall concrete/masonry structure surrounding the audience chamber and a multi-configuration stage shell that varies the stage depth. Together, these elements form the room’s acoustical volume to strike a balance between room reverberation and loudness. Multi-layer and stiff, curved surfaces are suspended above the forestage and audience seating, positioned at sidewalls within the forestage/audience seating transition zone, and located at rear wall/ceiling interfaces to provide timely and supportive reflections for clarity and envelopment. Since the hall must facilitate many types of uses, particularly those that utilize amplified sound from audio loudspeakers and therefore desire less room reverberation and reflections that would otherwise reduce clarity, motorized sound-absorbing drapery can be deployed at the upper sidewalls, upper rear wall, and above the forestage ceiling reflector to reduce room liveness.

The Recital Hall’s tall volume coupled with concrete sidewalls, grout-filled masonry stage enclosure, and multi-layer wood/gypsum board rear wall support broadband sound reflections and extended reverberation. Thick, projective sidewalls onstage and flanking audience seating combined with curved ceiling reflectors provide timely full-frequency reflections both to musicians onstage and the audience. Slight angling of house sidewalls in both plan and section and prevents the trapping of sound between otherwise parallel walls. Tight, multi-layer curves covered with thin felt on the audience rear wall soften reflections returning back to the audience from behind and to the stage. Motorized, sound-absorbing curtains deployed from slots at corners between walls onstage and surrounding the audience accommodate music wanting a drier acoustical environment. Varying angles and facets on the upper sidewalls diffuse sound to further immerse the audience with sound from all directions.

At both the Performance Hall and Recital Hall, conditioned supply air is delivered slowly beneath audience seats, where it gains heat and starts rising to the upper volume to be extracted. This allows a wide dynamic range of full-spectrum music to be produced and heard, down to a true pianissimo level, without being masked by background noise from air handling systems.

Audio systems in the Performance Hall and Recital Hall accurately reproduce high-fidelity, full-spectrum audio and focus sound on audience seating areas to minimize reflections from room surfaces. The Performance Hall has a sophisticated immersive video system to display high resolution video presentations and art on the stage surround. LED displays on walls flanking the stage can be used for image magnification of camera shots from multiple camera positions. Video switchers allow content to be broadcast to the large LED display and surround sound audio system at the Outdoor Plaza. Computer workstations provide capabilities to record, edit and create AV content for capturing and producing events throughout the facility.
