Last Call for Experts: FAA Aircraft Noise Advisory Committee Nominations Due August 10
FAA Aircraft Noise Advisory Committee (Deadline Coming) The FAA is currently accepting nominations for its Aircraft Noise Advisory Committee (ANAC), with a nomination deadline of August 10, 2026. The committee will examine topics such as alternative aircraft noise metrics, the 65 dB threshold, community impacts, and future noise policy. For more information, please see the FEDERAL REGISTER. This intersects with our work on ASA Standards—specifically, S1.4 – Sound Level Meters, S1.11 – Octave-Band Filters, S12.9 – Environmental Noise Measurement and S12.62 – Outdoor Sound Propagation. As aviation noise policy evolves, so must the measurement standards that support it. Experts with experience in environmental acoustics, instrumentation, airport operations, and community noise […]
A Legacy of Innovation, Leadership, and Service: Remembering Eric E. Ungar
The Acoustical Society community mourns the passing of Eric E. Ungar, who died on June 14, 2026, at the age of 99. Dr. Ungar was one of the foremost figures in structural acoustics and vibration engineering and a longtime leader within the Acoustical Society of America. A past ASA President (1991–1992), he made pioneering contributions to the understanding of vibration isolation, structural damping, mechanical mobility, and structure-borne sound. In recognition of his outstanding contributions to the field, he was awarded the Trent-Crede Medal in 1983. His research and professional service helped shape the technical foundations on which much of the modern practice of vibration and shock engineering rests. Dr. Ungar’s […]
Public Review Announcement + Call for Members
The following standards are currently open for public review and comment. ANSI public review and comment provides an opportunity for stakeholders and the public to review proposed standards and submit feedback before approval. This process helps ensure standards are developed through openness, balance, consensus, and due process. A call for members (ANS Consensus Bodies) is being issued to invite organizations that may be directly and materially affected by a proposed standard to participate in its development and review process. Participants contribute technical input and help ensure the standard reflects balanced stakeholder representation. Proposed Reaffirmation of ASA/BSR S1.15-2021/Part 1 / IEC 61094-1:2000 (R20XX), Electroacoustics – Measurement microphones – Part 1: Specifications […]
PINS Announcement: ASA/BSR S12.54-20XX / ISO 3744:2025
PINS Announcement: Standard Revision Initiated A Project Initiation Notification System (PINS) announcement has been published in the ANSI Standards Action, marking the start of an American National Standard revision. This announcement signals an opportunity for stakeholders to get involved early in the process by reviewing the PINS and providing input. This project addresses acoustics — determination of sound power levels and sound energy levels of noise sources using sound pressure, supporting consistent engineering methods across applications. You can view the ANSI Standards Action listing here: ANSI Standards Action Directly and materially interested parties wishing to receive more information or to submit comments are to contact the ASA Standards Office at https://asastandards.org/contact/ […]
Honoring the Legacies of Richard L. McKinley and William A. Ahroon, Ph.D.
The acoustics community mourns the loss of two distinguished leaders whose work helped shape modern standards in noise measurement and hearing protection: Richard L. McKinley and William A. Ahroon, Ph.D. Both were dedicated members of the Acoustical Society of America, and Rich was recognized as an ASA Fellow for his significant contributions to the field. Their passing is a significant loss to the ASA Standards Program and its Accredited Standards Committees for Bioacoustics (S3) and Noise (S12), where their expertise, leadership, and commitment to collaboration made a lasting impact — and to the Acoustical Society of America community as a whole. Decades of Dedication to Noise Research and Standards Richard […]
