Audio Coverage Uniformity in Listener Areas
Document Number:
AVIXA A102.01:2017 (Formerly ANSI/INFOCOMM A102.01:2017)
Type of Standard:
This Standard defines parameters for characterizing a sound system’s coverage ofdefined listener areas. It provides performance classifications and measurement procedures to assess the uniformity of coverage of a sound system’s early arriving sound, with the goal of achieving consistent sound pressure levels throughout defined listener areas. This is accomplished by measuring the uniformity of coverage of the early arriving sound from the loudspeaker system throughout the listener area.

Who should use this standard?

The procedures in this Standard apply to sound reinforcement and audiovisual (AV) presentation systems. These systems are implemented in a variety of applications including conference rooms, training rooms, classrooms, auditoria, theatres, houses of worship, and other venues where sound reinforcement is employed. Additionally, the metrics and classifications in this Standard may be used to establish design criteria for new systems.

AVIXA's consensus standards development process is accredited by ANSI, a private, non-profit organization that administers and coordinates the U.S. voluntary standardization and conformity assessment systems. ANSI is the sole U.S. representative of the two major non-treaty international standards organizations, the International Organization for Standardization (ISO), and, via the U.S. National Committee (USNC), the International Electrotechnical Commission (IEC). Accreditation by ANSI signifies that the procedures used by AVIXA in connection with the development of American National Standards meet the Institute's essential requirements for openness, balance, consensus, right to appeal, and due process.
