This Standard provides a procedure to measure and classify the uniformity of early arriving sound from a sound system across a listener area.
The performance of a sound system can be characterized by several factors including uniformity of coverage, tonal balance and consistency, gain before feedback, and maximum sound pressure level.
This Standard focuses on the uniformity of coverage of a sound system’s early arriving energy to listener area. An ideal sound system design allows all listeners to hear reproduced content at approximately the same sound pressure level independent of the listener’s position in a designated listener area.
This performance Standard provides a procedure to measure and a means to classify the uniformity of coverage.
