The fall issue of Acoustics Today is now out! The cover features a drawing of the Riverbank Laboratories with a detailed view of the reverberation chamber (image credit: courtesy of JSTOR and Eric Wolfram, Riverbank Acoustical Laboratories), from an article about the challenge of determining sound absorption of a given material.

Other topics in this issue:

• Current research into the high-frequency range of human hearing and its impact on our understanding of speech
• Using focused ultrasound for incisionless brain surgery
• Using acoustic streaming to help deliver drugs to hard-to-reach areas of the body
• The field of Conservation Bioacoustics, where passive sound monitoring is used to monitor an environment and animals
• Acousto-optic sensing, or the use of light to measure acoustic phenomena

Plus there’s an interview with Jennifer Cooper of the Johns Hopkins Applied Physics Laboratory, updates on the Proceedings of Meetings on Acoustics, a story of a retired acoustician who now shares his expertise as a substitute teacher, information about ExploreSound.org, and announcement of the winners of the ASA Awards at the 2023 International Science and Engineering Fair.
