We’re delighted to announce today the publication of a newly adopted ASA Standard – ASA/ANSI S3.55-2023/Part 8/IEC 60318-8:2022 titled: Electroacoustics – Simulators of human head and ear – Part 8: Acoustic coupler for high-frequency measurements of hearing aids and earphones coupled to the ear by means of ear inserts. This standard was approved via balloting by the volunteer members of our ASC S3 Bioacoustics Committee, chaired by William J. Murphy with Stephenson and Stephenson Research & Consulting. The abstract is: “This part of IEC 60318 describes an acoustic coupler for loading a hearing aid or insert earphone with a specified acoustic impedance when testing its acoustic performance, in the frequency […]

Our Condolences with the Passing of Sanford “Sandy” Fidell, PhD
All of us with the ASA Standards team express our condolences to the family, colleagues and friends of Sanford “Sandy” Fidell, PhD, who passed away at 77 years old in late February. Dr. Fidell was a longtime and dedicated ASA and ASA Standards Member volunteer (and past ASA Fellow) who played an instrumental role in advancing the field of acoustics through his work in acoustics standards development. Over the course of his long career in acoustics, Dr. Fidell became one of the world’s leading experts in the field of transportation noise annoyance and community tolerance levels. He began his transportation noise research and consulting work in the Los Angeles office […]
