SC-04-01 meeting report, San Francisco, 2006-10
Report of the meeting of SC-04-01 Working Group on Acoustics and Sound Source Modeling of the SC-04 Subcommittee on Acoustics, held in conjunction with the 121st AES Convention in San Francisco, CA, USA 2006-10-05.The meeting was convened by Chair B.C. Olson.
The agenda, and the report of the meeting held on 2006-05-20 in Paris, France, were accepted as written.
Open ProjectsAES-4id-R: Review of AES-4id-2001: AES information document for room acoustics and sound reinforcement systems - Characterization and measurement of surface scattering uniformity
Project scope: This document provides guidelines for characterizing the uniformity of scattering produced by surfaces from measurements or predictions of scattered polar responses. In this context, the surface scattering is quantified in terms of a single diffusion coefficient.It was proposed to reaffirm this document as soon as possible. The meeting also felt that this project needs to be revised after it has been reaffirmed. R. Sauro has undertaken to submit proposals for revision.
Assigned to: SC-04-01, Initiated: 2001, Intent: Reaffirmation,
Target: 2006 Current goal: CFC for reaffirmation, Goal date: 2006-11
AES20-R: Review of AES20-1996 (r2002): AES recommended practice for professional audio - Subjective evaluation of loudspeakers
Project scope: The recommendations of this document apply to the subjective evaluation of sound reproduction of loudspeakers in domestic listening environments and in professional environments of similar acoustics. The recommendations apply most directly to user-installed free-standing and in-wall loudspeakers.Status: No action requested or required. It was proposed to reassign this maintenance project to SC-04-03 as a more relevant group.
Assigned to: SC-04-01, Initiated: 2002-05, Intent: Review
Target: 2007 Current goal: Status report, Goal date: Continuing
Development ProjectsAES-X081: Liaison with International Organization for Standardization (ISO) SC 43-2 WG25
Project scope: to formalize the working relationship between AESSC SC-04-01 and ISO SC 43-2 WG25The meeting proposed that this liaison should be reanimated prior to the revision of AES-4id.
Assigned to: SC-04-01, Initiated: 1999-04, Intent: Liaison
Target: Continuing Current goal: Status report, Goal date: Continuing
AES-X083 : Loudspeaker Polar Radiation Measurements
Project scope: to specify unified loudspeaker far-field polar radiation measurement practice to provide data suitable for room acoustic modeling programsDetailed changes to the current draft were discussed and revisions will be forwarded by Olson to M. Yonge.
Assigned to: SC-04-01, Initiated: 1999-09, Intent: Information document
Target: 2006 Current goal: Revised PWD, Goal date: 2006-12
Liaisons:There were no other liaison issues.
New Projects:No new projects were received or proposed.
New business:There was no new business.
The next meeting will be scheduled in conjunction with the AES 122nd Convention in Vienna, Austria, 2007-05.
