    How Classroom Acoustics Fail Autistic Students and Teachers

    We know noisy classrooms and learning environments can negatively impact students and teachers. However, these problems can be compounded for those with autism. We talk to Carmen Rosas-Pérez (Heriot-Watt University) about her research to better understand the experiences of autistic people in daily life acoustic environments. Associated paper: Carmen Rosas-Pérez, Laurent Galbrun, Mary E. Stewart, and Sarah R. Payne. "How can anyone learn or teach? Experiences of autistic people with soun...

    Can Sound Be Used to Diagnose Arteriosclerosis?

    Because cardiovascular disease is the world's leading cause of death, researchers have been looking for ways to diagnose it early. Low-frequency sounds have been used to assess the elasticity of blood vessels, but until now, the elastic waves being studied were too fast to get precise measurements. Sibylle Gregoire (INSERM) discusses how here team has been able to image a different type of elastic wave, opening up the possibility to more precise assessments and diagnosis of cardiovascul...

    Ultrasound Transducers for Measuring Martian Wind Speeds

    We have yet to fully understand the wind on Mars, even though it transfers heat, momentum, and molecules from the surface. Traditionally, heat loss and motion detectors have been used to measure wind speeds. Robert D. White (Tufts University) discusses his team's work on ultrasound transducers that may offer a more precise way to measure turbulent eddies on the Red Planet.Associated paper: Robert D. White, Rishabh Chaudhary, Zijia Zhao, Luisa Chiesa, Ian Neeson, and Don Banfield. "Model...

    Acousto-Optics: Sensing Sound with Light

    In this episode, we dive into the world of acousto-optics, where light is used to visualize and measure sound-- particularly acoustic phenomena that are difficult to observe. Samuel Verburg (Technical University of Denmark) and Kenji Ishikawa (NTT Communication) share the history of this field of research, as well as discuss modern day applications and potential uses for acousto-optic sensing in the future. Read the associated article: Samuel A. Verburg, Kenji Ishikawa, Efren Fernandez-Grande...

    New Research Roundup: Music as Noise, Instruments as Dynamic Sound Sources, and Modeling Piano Soundboards

    This episode highlights three recent articles from the field of musical acoustics. First, we talk to Elvira Brattico (Aarhus University) about her research into what causes a person to experience music as noise. Next, Stefan Weinzierl (Technical University of Berlin) discusses how a musician's movement during a performance will impact the notes listeners hear. Finally, Pablo Miranda Valiente (University of Southampton) discusses his work to develop a model that shows the impact a piano soundb...

    Why don't speech recognition systems understand African American English?

    Most people have encountered speech recognition software in their day-to-day lives, whether through personal digital assistants, auto transcription, or other such modern marvels. As the technology advances, though, it still fails to understand speakers of African American English (AAE). In this episode, we talk to Michelle Cohn (Google Research and University of California Davis) and Zion Mengesha (Google Research and Stanford University) about their research into why these problems with spee...

    Student Paper Competition: Emotions of Drums, Acoustic Black Holes, Ocean Noise, and More!

    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...

    Measuring the Big Impact Vibration Has on Tiny Microphones

    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...
