Interdependent impact of acoustics, psychoacoustics, electroacoustics, and usage on design of arena facilities

Abstract

Current and future usage priorities arc explored for large arena facilities. The impact of such usage is a significant factor in determination of acoustic and psychoacoustic criteria appropriate for the type and relative number of projected arena events (basketball, concerts, hockey, etc.). Usage‐related parameters that affect acoustics and the sound reinforcement system design are room shape, volume, type and distribution of materials, HVAC ambient noise exterior noise intrusion (overflight), crowd noise for various event types, and associated crowd size. Speech intelligibility, frequency response, peak sound level, uniformity of coverage, time delay effect, and qualitative issues arc discussed in conjunction with these usage related design parameters. Design constraints imposed by the acoustics of large arenas are discussed as they relate to arena usage, operation, and sound reinforcement system configuration. Specific examples will be cited from experience with McNichols Arena (Denver), Arco Arena (Sac...
