Continuous Active Sonar's Impact on Killer Whales

10/15/24 • 13 min

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.

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.

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.
