SC-04-01 meeting report, London, 2010-05

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 128th Convention in London, 2010-05-23

The meeting was convened by chair W. Ahnert

The agenda and the report of the previous meeting 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: No action was requested or required.

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: No action was requested or required.

Liaisons:

None

New Projects:

A new project as a continuation for standard AES56-2008 has been proposed:

AES-X193: Sound source modeling - Array and Cluster polar radiation data prediction
Proposed scope: The standard will specify how the angular measurements of polar radiation data for arrays or cluster arrangements of loudspeakers or their modules shall be made and documented. This acquired data is used to predict the complex radiation behavior of arrays and clusters and is suitable for application in room acoustic, electro-acoustic, and sound system design.

A first draft will be elaborated in time for the next meeting in San Francisco, 2010-11: responsible: Ahnert and B.C. Olson

New business:

There was no new business.

The next meeting will be scheduled in conjunction with the AES 129th Convention in San Francisco US, 2010-11.
