Student Paper Competition: Moth-Inspired Microphones, Rocket Noise Mitigation, and Deformable Microphone Arrays

Across Acoustics

Could moths’ hearing be the key to figuring out how to localize sound with tiny microphones? How do we prevent rocket launch noise from damaging the ship’s payload? Is it possible for algorithms to account for microphone arrays that don’t stay in a rigid structure? These are some questions considered by Acoustical Society students who won the latest round of the POMA Student Paper Competition from the 183nd meeting of the ASA. In this episode, we interview the three competition winners, Lara Díaz-García, Mara Salut Escarti-Guillem, and Kanad Sarkar, about their research.
