Description: |
One of the fundamental goals of sound system performance for both speech reinforcement and program audio is the delivery of consistent 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 procedure to measure this spatial coverage, and criteria for use in the design and commissioning of audio systems. Read an overview |

InfoComm'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 InfoComm International 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.
