    Things That Go Boom

    In this episode, we explore things that go boom: from volcanic eruptions to underwater ordinances to the (relatively) tiny explosions of gunshots. Thomas Blanford (University of New Hampshire) joins us as a cohost as we discuss the use of high-amplitude acoustic sources in research with three members of a special session on the topic from the Ottawa ASA meeting: Steve Beck (Beck Audio Forensics), Daniel Bowman (Pacific Northwest National Laboratories), and Andrew McNeese (University of Texas ...

    Show Your Scattering Coefficients

    The phenomenon of acoustic scattering, when a sound wave bounces off a surface and is redirected in different directions because of the surface texture, has been recognized since ancient Greece. Accounting for acoustic scattering when designing a built space, however, can be tricky. In this episode, we speak with Michael Vorländer (RWTH Aachen University) about his work to develop a general guideline for estimating the effects of acoustic scattering from a given surface. Associated paper: Mic...

    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 (...

    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 ...

    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. "Auditory masking of tonal and conspecific signals by continuous act...
