In this episode, find out what the next generation of acousticians is researching! In this episode, we talk to the latest round of POMA Student Paper Competition winners, from the joint 188th meeting of the ASA and the 25th International Congress on Acoustics held in New Orleans in May 2025. Their topics include:

- Using the spatial decomposition method to parameterize acoustic reflections in a room (Lucas Hocquette, LAcoustic)

- Visualizing nonlinearities in a bolted plate system with digital image correlation (Nicholas Pomianek, Boston University)

- Analyzing the how people pronounce the word "just" in casual speech (Ki Woong Moon, University of Arizona)

- Modeling strings of historical instruments that no longer make sound (Riccardo Russo, University of Bologna)

- Improving automatic music mashup generators (Yu Foon Darin Chau, Hong Kong University of Science and Technology)

Studying bats' hearing can be tricky due to their small size, making certain styles of measurement used for larger echolocating mammals unavailable to researchers. In this episode, we talk to Victoria Fouhy and Michael Smotherman (Texas A&M University) about their work to develop a noninvasive method to study cortical auditory evoked potentials in bats, thereby allowing scientists to better understand how these animals process echolocation information.

Associated paper:

You may have heard of the "ghost army" of World War II—a set of rubber tanks used by the US Army to mimic active battlefields in Europe. What you may not know was the tanks were accompanied by an equally fake soundtrack of battle noises. Even more surprising? This "sonic deception" was developed by a team of the ASA's founding members whose contributions were almost lost to history. In this episode, we talk with Walter Montano (ARQUICUST Argentina Peru) about the innovations that helped save thousands of lives during the war.
