Report of the Meeting of the SC-04-09 Working Group on Assessment of acoustic annoyance of the SC-04 Subcommittee on Acoustics, held online, 2020-05-27.
Due to scheduling confusion on the part of the chair, the meeting was opened by AESSC Standards Manager Rich Cabot at 1600 GMT and joined about ten minutes later by chair David Josephson. The patent policy notice was read and no objection was heard to the agenda or the previous meeting’s minutes.
In attendence were R. Cabot, B. Olson, M. Rafaelof, J. Boley, L. Neumann, S. Norcross, J. Schlittenlacher, J. Page, P. Mapp, S. Kramer, D. Josephson.
The members participating introduced themselves, from a variety of organizations including traditional AES content creation interests and from other areas of environmental noise assessment.
New projects:
The open project is AES-X248, Assessment of Acoustic Annoyance. This remains preliminary work as several research organizations are developing ways to assess both audibility and annoyance. The WG heard from Menachem Rafaelof from NASA on an upcoming AES paper now in final review at NASA on a loudness based audibility model, using a variant of the Cambridge methods. We heard also from Josef Schlittenlacher, now at Manchester University, about the progress of ISO/AWI 532-3, which standardizes some aspects of the Cambridge loudness method. Finally we heard from Juliet Page of the US Department of Transportation’s Volpe Lab which is working on the next release of the Advanced Acoustics Model. AAM is initially intended for aircraft noise analysis but the methods are equally applicable to any complex sound radiating system (the source model is a sphere where sound radiation is characterized for arbitrarily narrow segments of the sphere) which can be propagated to listeners at a distance.
