This episode, we talk to a new round of POMA Student Paper Competition winners from the 185th ASA Meeting in Sydney about their exciting research endeavors:- An analysis of how drums convey emotion- A method to assess stress caused by vibration in acoustic black holes- An improved estimator for background noise in underwater signals- A model to help remove distortion from the sound fields of parametric array loudspeakers- A numerical study of a little-understood phenomenon in bowed-string ins...

The tiny microphones used inside hearing aids can be very sensitive to vibration of the device, resulting in annoying feedback. Testing how sensitive these microphones are to vibration has been a problem that plagued engineers. In this episode, we talk to Charles King and Chris Monti of Knowles Electronics about their innovation to measure microphone vibration sensitivity.Associated paper: Charles B. King and Chris Monti, "Microphone vibration sensitivity: What it is, why it is important, and...

Speech Science courses are a key component to the curriculum within a variety of disciplines, but coursework is frequently lacking in terms of representation of those from different cultural and linguistic backgrounds. In this episode, we talk to Melissa Baese-Berk (University of Chicago) and Paul Reed (University of Alabama), about why it's so important for instructors to use a variety of voices in the classroom, and how to talk about other ways of speaking when one feels ill-equipped to do ...

In the aftermath of World War II, New York City wanted to built a new home for its orchestra, the New York Philharmonic, and secure its place a cultural center of the world. In this episode, we talk to the Paul H. Scarbrough (Akustiks, LLC) about where these plans went awry and the multiple renovations over many decades to fix the hall. Read the associated article: Paul H. Scarbrough. (2023) “David Geffen Hall and the Evolution of Acoustics at Lincoln Center,” Acoustics Today 19(4). http...

It's not always feasible to measure the sound field generated by an acoustic source; instead, scientists have to model to come up with a best guess for the missing pieces of the sound field. In this episode, we talk to Efren Fernandez-Grande and Xenofon Karakonstantis (Technical University of Denmark) about their new machine learning method to reconstruct sound fields. Associated paper: Efren Fernandez-Grande, Xenofon Karakonstantis, Diego Caviedes-Nozal, and Peter Gerstoft. "Generative model...

While analyzing acoustic data from the Mariana Archipelago, Angela Szesciorka (Oregon State University) noticed something funny: a signal unlike any other she'd seen. It showed up over and over, and only seemed to occur at night. In this episode, we talk to Szesciorka about this mystery call and what animal possibly made it. Associated paper: Angela R. Szesciorka, Jennifer L. K. McCullough, and Erin M. Oleson. "An unknown nocturnal call type in the Mariana Archipelago." JASA Express Letters&n...
