Audio Coverage Uniformity in Enclosed Listener Areas - InfoComm International Performance Standard

One of the fundamental goals of sound system performance for both speech reinforcement and program audio is the delivery of uniform coverage in the listening area. A well executed audio system design is one that allows all listeners to hear the system at approximately the same sound pressure level throughout the desired frequency spectrum range, no matter where positioned in the designated listening area. This standard provides a characterization of and a procedure to measure this spatial coverage, with criteria for use in the design and commissioning of audio systems.
