SC-04-01 meeting report, Munich, 2009-05

Report of the SC-04-01 Working Group on Acoustics and Sound Source Modeling, of the SC-04 Subcommittee on Acoustics meeting, held in conjunction with the AES 125th Convention in Munich, 2009-05-09

The meeting was convened by chair Wolfgang Ahnert

The agenda and the report of the previous meeting, 2008-10-02, were accepted as written.

Open projects:

AES56-R: Review of AES56-2008, AES standard on acoustics - Sound source modeling - Loudspeaker polar radiation measurements

Intent: Review of Standard AES56-2008, Initiated: 2008, Intent Target: 2013
Goal: Status Report, Goal date: Continuing

Status: AES standard AES56-2008 was reprinted with addenda, 2009-03-10.

Development projects:

AES-X081: Liaison with International Organization for Standardization (ISO) SC 43-2 WG25
Project scope: to formalize the working relationship between AESSC SC-04-02 and ISO SC 43-2 WG25.

Assigned to: SC-04-01, Initiated: 1999-04 Intent: Liaison, Target: Continuing Current goal: Status report, Goal date: Continuing

Status: A new proposal has been made by R. Sauro to continue to work on section 2 of AES-4id. The working group is awaiting a Project Initiation Request. Project proposal must be expected during the next 4 weeks; otherwise this project will be closed.


There was a liaison between AES56-2008 and AES-5id-1997. It was intended to close AES-5id after AES56-2008 was published as a standard. We recommend not closing AES-5id because AES56-2008 does not cover the high resolution issues of speaker data.

New Projects:

A new project as a continuation for standard AES56-2008 has been proposed: Sound source modeling - Polar radiation measurements for loudspeakers used in arrays and clusters.

An online proposal will be submitted during the next 4 weeks.

New business:

There was no new business.

The next meeting will be scheduled in conjunction with the AES 127th Convention in N.Y. US, 2009-10.
