Across Acoustics

The COVID-19 pandemic forced many researchers in the fields of psychological and physiological acoustics to scramble to find new ways to perform hearing research that is traditionally done in the lab remotely. The Acoustical Society of America Technical Committee on Psychological and Physiological Acoustics launched the Task Force on Remote Testing (https://tcppasa.org/remotetesting/) in May 2020 with goals of surveying approaches and platforms available to support remote testing and identifying challenges and considerations for prospective investigators. In this episode, we discuss their findings with two of the co-authors of the resulting papers, Ellen Peng, of Boys Town National Research Hospital, and Erick Gallun, of Oregon Health and Science University.

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.

Over the past 100 years or so, ordnance has entered aquatic environments around the US at military testing and training sites. As these sites transition away from military use, it’s necessary to clean up unexploded ordnance that may have been left behind. We interview Kyle Dalton, one of the winners of the POMA Student Paper Competition from the 182nd meeting of the ASA, about his research regarding the modeling of these unexploded ordnances so they can be detected with sonar.

Does sound travel differently in Kentucky bourbon than it does in other types of alcohol? Stanley A. Cheyne of Hamden-Sydney College pondered this question before the 177th ASA meeting in Louisville, Kentucky. Twenty or so types of whiskey later, he’d made some interesting discoveries, both about whiskey and about how distilleries measure alcohol concentration. This episode we interview him about his resulting article in Proceedings of Meetings on Acoustics, “Sound speed measurements in ethanol/water solutions and Kentucky bourbon whiskey.”

Another meeting, another round of amazing student research! This episode, we talk to winners of the POMA Student Paper Competition from the 184th meeting of the ASA about their research into using machine learning to model concert hall reverberation time, the effect of clear speech on memory, noise from the Atlas-V rocket launch, the bridge force exerted on the string of a bowed instrument, and a new approach to underwater acoustic source localization.
