InfoComm releases first performance standard

The InfoComm International board of directors approved release of the association's first performance standard, The Audio Coverage Uniformity Performance Standard.

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 they're positioned in the designated listening area. The Audio Coverage Uniformity Standard provides a procedure to measure this spatial coverage and criteria for use in the design and commissioning of audio systems.

The procedures prescribed by this standard are intended to be used primarily for AV presentation systems in which audio is provided as a part of the system within an enclosed environment. These systems may be installed within a variety of AV applications, including conference rooms, training rooms, classrooms, auditoriums, theaters, and museum exhibits. This standard may also be applied to large-venue audio systems or any system that includes audio coverage within enclosed spaces.

The Audio Coverage Uniformity Standard is limited to uniformity measurements and specifically does not include testing or measurements for spectral response, time domain issues, or other parameters that may be required to assess the total performance of an audio system. Future standards may address other audio concerns.

"The ACU Standard was developed by InfoComm's Standards Committee and the Audio Coverage Uniformity Working Group to improve the listening experience in a wide variety of audio installations," said InfoComm International Executive Director Randal A. Lemke, Ph.D. "Architects, facilities managers, owners, and technology managers will benefit from a test which verifies that their audio system meets one important criterion of quality."

The ACU Standard was developed in an open process with consensus and transparency. InfoComm plans to submit the standard to the American National Standards Institute for adoption consideration in the next few weeks.

"The entire audiovisual industry is indebted to Audio Coverage Uniformity Task Group Chair Fred Ampel of Technology Visions, Performance Standards Planning Committee Chair Scott Walker [CTS-D, LEED AP] of Waveguide Consulting, and their team of volunteers who developed this important tool for AV consumers and technicians," Lemke said.

InfoComm honors industry leaders and pioneers

During InfoComm 09, InfoComm International presented its Distinguished Achievement Award to Robert S. Simpson during the InfoComm International President's VIP Reception. In 1964, Simpson co-founded Electrosonic, a worldwide audiovisual company that operates as a systems integrator, product manufacturer, and service provider for AV facilities. Based in the United Kingdom, Simpson is a frequent writer and lecturer on audiovisual and lighting control topics, and is author of the highly regarded guidebooks Effective Audio Visual, Videowalls, Videowalls—The Book of the Big Electronic Image, and Lighting Control—Technology and Applications. He has worked on numerous museum, theme park, and permanent exhibition projects worldwide, and has contributed to the design concepts of many of the company's products.

InfoComm's Distinguished Achievement Award is the highest honor bestowed on an industry member by the association. "When the InfoComm Board of Directors considers honoring a member with the Distinguished Achievement Award, two major criteria are applied: the career accomplishments of an individual and the individual's contribution to the AV industry," said Randal A. Lemke, Ph.D., executive director, InfoComm International. "Bob Simpson is not only known as 'The Father of AV' in the U.K., he is one of the great visionaries that has changed the way the entire world experiences AV, and InfoComm is proud to recognize his achievements and lasting legacy."
