    Reducing Shipping Noise for Fatter, Happier Marine Mammals

    Human-made noise from shipping is an ongoing problem for aquatic life. However, actually implementing measures to reduce noise can be costly and time consuming-- a risk many ship makers don't want to take without knowing how effective those methods will be. In this episode, we talk with Vanessa M. ZoBell (Scripps Institution of Oceanography) about her research that simulates the impacts of various strategies, with hopes for finding the most effective methods to improve the lives of our underw...

    Acoustic Levitation and Trapping

    Acoustic levitation allows objects to be suspended in air or in liquids without falling. In this episode, we speak with Philip Marston (Washington State University) about the history of acoustic levitation, and his work to translate previous research into terminology more accessible to modern readers and those outside of the field of physics. Associated papers:- Philip L. Marston. "Trapping in acoustic standing waves: Effect of liquid drop compressibility." J. Acoust. Soc. Am. 154, R5–R6 (202...

    Student Paper Competition: Modeling Trumpets and Falcon 9 Flyback Noise

    This episode is part two of our interviews with the POMA student paper winners from our meeting in Ottawa. First, we talk with Miranda Jackson (McGill University) about her research regarding modeling the mouthpiece and bells of brass instruments. Next, Mark C. Anderson (Brigham Young University) talks about the noise created by the Falcon 9 boosters as they fly back to Earth and the impact that noise can have on surrounding communities. Associated papers:- Miranda Jackson and Gary Scavone. "...

    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...
