Abstract
Rosen Concert Hall, in the Broyhill Music Center at the Appalachian State University Hayes School of Music, is a beloved 400-seat recital hall designed in the 1980s by architect Dennis Yates and acoustician Rein Pirn (Acentech/BBN) and was featured in the 1990 ASA publication “Acoustical Design of Music Education Facilities.” The hall was designed for pipe organ, vocal chorus, and smaller classical instrumental ensembles, with significant variable absorption in the form of curtains. Since then, the school’s program has broadened, and the hall is now used also for jazz band, large wind ensemble, and some amplified forms. A 2017 study included acoustical measurements in the hall, listening sessions with eight different ensembles in the hall, and discussions with faculty and staff. These resulted in detailed recommendations for acoustical improvements and new audiovisual equipment. The school has completed two recommended acoustical improvements, with positive results: hinged absorptive wall panels surrounding the platform, and extended reflective canopy. Users report improved on-platform clarity for louder ensembles, and better self-hearing and presence of sound for downstage performance locations.
