• A New Way to Diagnose Osteoporosis

  Ultrasonic tomography has been applied in many fields, from geophysics to engineering, and now to medicine. In this episode, we talk with Aaron Chung-Jukko and Peter Huthwaite (Imperial College London) about their work to develop an ultrasonic tomography algorithm that can be used to assess fracture risk in bones, and, as a result, be used as a noninvasive way to diagnose osteoporosis.Associated paper:- Aaron Chung-Jukko and Peter Huthwaite.

• Iconicity and Sound Symbolism

  For a long time, it was believed that words were mostly arbitrary symbols. However, with advances in our ability to study speech, it has become clear that we must reconsider the fundamental relationship between words' sounds and their meanings. In this episode, we talk to two of the editors of the Special Issue on Iconicity and Sound Symbolism, Aleksandra Ćwiek and Susanne Fuchs (Leibniz-Centre General Linguistics), about research in the issue that examined these connections. Read all the articles from the special issue here!Read more from The Journal of the Acoustical Society of America (JASA).Learn more about Acoustical Society of America Publications.Music Credit: Min 2019 by minwbu from Pixabay.

• Reproducing Soundscapes with the AudioDome

  Recreating the natural hearing experience has long challenged researchers who study auditory perception. Recently, ambisonic panning has been developed as a method to accurately reproduce soundscapes. In this episode, we talk with Nima Zargarnezhad and Ingrid Johnsrude (Western University) about their research testing the accuracy of the "AudioDome," a device that using ambisonic panning to simulate soundscapes in the lab.Associated paper:- Nima Zargarnezhad, Bruno Mesquita, Ewan A Macpherson. and Ingrid Johnsrude.

• An Archeoacoustic Look at Two Hindu Temples

  Much of the research into the historical acoustics of worship spaces has focused on Christian churches or Islamic mosques. However, little is known about the acoustic history of Hindu worship spaces, despite Hinduism being the third largest religion in the world. Shashank Aswathanarayana and Braxton Boren (American University) share their efforts to fill this knowledge gap by studying the acoustics in Hindu temples from the 8th and 15th centuries. Associated paper: Shashank Aswathanarayana and Braxton Boren. "Acoustic analysis of two Hindu temples in Southern India."

• Student Paper Competition: Environmentally Friendly Acoustic Design, Spatial Impulse Response Measurements, and Acoustic Spectrometers

  This episode showcases the latest winners of the POMA Student Paper Competition: First, Jonathan Michael Broyles (University of Colorado, Boulder) discusses his database to help acoustical consultants design more environmentally friendly spaces. Next, John Latta (University of Nebraska - Lincoln) shares his work regarding spatial impulse response measurements. Finally, Michelle Ruth Crouse (California State University, Dominguez Hills) talks about the acoustic spectrometer she created using off-the-shelf parts. Associated papers:Jonathan Michael Broyles and Wil Srubar, III.
