    An Ultrasound-Based Touchscreen

    Current touchscreen technology has its limitations. In this episode, we talk with Jérémy Moriot (Université de Sherbrooke) about his team's development of an ultrasound-based system that not only can work with various types of surfaces, but can also detect multiple touches at the same time. Associated paper: Maxime Bilodeau, Jérémy Moriot, Joëlle Fréchette-Viens Raphaël Bouchard, Philippe Boulais, Nicolas Quaegebeur, and Patrice Masson. "Embedded real-time ultrasound-based multi-touch sy...

    Continuous Active Sonar's Impact on Killer Whales

    When pulsed active sonar was found to cause mass strandings of whales, researchers turned to the quieter continuous active sonar for underwater monitoring. In this episode, Brian K. Branstetter (Naval Facilities Engineering Systems Command Pacific) shares his work to find out how this sonar affects killer whales. Associated paper: Brian K. Branstetter, Michael Felice, Todd Robeck, Marla M. Holt, and E. Elizabeth Henderson. "Masking in continuous sonar noise." J. Acoust. Soc. Am. 156 (2024). h...

    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...
