Audio Standards

The uptick in cultural performance events, multi-media arts curricula, audio traffic control on college campuses and media production facilities for massive open online courses are also drivers for our attention to standards suites that contribute to the safety and sustainability of the cultural mission of the education industry.

“A Dance to the Music of Time” | Nicolas Poussin (1640)

 

“The voice of the intellect is a soft one,

but it does not rest until it has gained a hearing.”

— Sigmund Freud

 

The education industry provides a large market for occupancy classes — such as athletic stadiums, student assembly spaces, performance theaters, large lecture halls– that depend upon effective audio systems*.   To an unexpected degree the structural engineering, specification of materials and electrical system design and operation is informed by acoustical considerations.  So does the integration of fire safety and mass notification systems into normal state enterprises it is wise to follow and, ideally, participate in leading practice discovery and promulgation of audio standards.

The Audio Engineering Society — one of the first names in this space — has a due process platform that welcomes public participation.   It has released a number of “Calls for Comment” on existing consensus products.   You may find the list at the link below:

AES Standards Development

Note that AES56-2008 (r2019), AES standard on acoustics – Sound source modeling – Loudspeaker polar radiation measurements his out for public review.

Comments are due within 6 weeks of the the July 7th so that means comments are due mid-August, or thereabouts.  (See the AES Public Commenting policy on its Standards Development landing page, linked above.   You are encouraged to communicate directly with the Direct communication with the standards staff at Audio Engineering Society International Headquarters, 551 Fifth Avenue, Suite 1225, New York NY 10176,  Tel: +1 212 661 8528

We are happy to discuss how the AES suite effects the safety and sustainability agenda of the emergent #SmartCampus any day at 11:00 AM Eastern time.   We also place the AES suite on the standing agenda of our Arts & Entertainment facilities  monthly teleconference.  See our CALENDAR for the next online meeting.  Use our login credentials at the upper right of our home page.

We also collaborate with experts active in the IEEE Education & Healthcare Facilities Committee (IEEE E&H) since much of the AES suite references, and borrows from, International Electrotechnical Commission system integration and interoperability standards.   That committee meets online again four times monthly in European and American time zones.  The meeting dates are available on the IEEE E&H website

*Mass notification systems are governed by NFPA 72 and, while life safety wiring is separate from other wiring, the management of these systems involve coordination between workgroups with different business objectives and training.

The education industry provides a large market for occupancy classes — such as chapels, performance theaters, large lecture halls and athletic stadiums — that depend upon effective audio systems*.   To an unexpected degree the structural engineering, specification of materials and electrical system design and operation is informed by acoustical considerations.  Of course, the primary business function of these facilities is worship, education and entertainment, but with the integration of fire safety and mass notification systems into normal state enterprises it is wise to follow and, ideally, participate in leading practice discovery and promulgation of audio standards.

The Audio Engineering Society — one of the first names in this space — has a due process platform that welcomes public participation:

AES Standards Development

AES has released a new draft of AES73id-xxxx, AES information document for acoustics – Loudspeaker driver comparison chambers.   From the project abstract:

Acoustic performance measurements on loudspeaker drivers that are measured in different sites or with different equipment or methods are subject to variations in accuracy and repeatability. Similarly, end-ofline loudspeaker test systems often utilize small, arbitrarily shaped, driver measurement chambers that do not correlate from line to line, or from site to site. This document is motivated by the need for engineers in different locations to share accurate measurement data on specific or same type loudspeaker drivers and addresses some of the factors affecting repeatability of measurements in different locations.

Comments are due within 6 weeks of posting which means that since the exposure draft was released on March 3rd, the comments are due by mid-April, or thereabouts.

The education industry provides a large market for occupancy classes — such as chapels, performance theaters, large lecture halls and athletic stadiums — that depend upon effective audio systems*.   Of course, the primary business function of these facilities is worship, education and entertainment, but with the integration of fire safety and mass notification systems, it is wise to participate in leading practice discovery and promulgation of audio standards.   Acoustic and audio standards can affect the design and operation of a building because it affects the occupancy patterns.

The Audio Engineering Society has a due process platform that is open for public participation:

AES Standards Development

Two exposure drafts are open for public comment:

AES5 | Recommended practice for professional digital audio — Preferred sampling frequencies for applications employing pulse-code modulation.  This standard covers the use of certain preferred sampling frequencies in applications employing pulse-code modulation where there is a need for interchange of high-fidelity digital audio programs with a minimum of transcoding complexity.  Posted September 18th

AES70-3 |  Standard for audio applications of networks.  This standard defines a scalable control-protocol architecture for professional media networks. AES70 addresses device control and monitoring only; it does not define standards for streaming media transport.  Posted September 28th.

Comments are due within 6 weeks of posting.   As of today the commenting period is closed, though no update appears on the AES standards home page.  It is possible, however, for ideas and data to be forwarded for consideration by an individual on the technical committee through its rapporteur.  You are encouraged to communicate directly with the Direct communication with the standards staff at Audio Engineering Society International Headquarters, 551 Fifth Avenue, Suite 1225, New York NY 10176,  Tel: +1 212 661 8528
