Bats vs. Dolphins: Ultimate battle of sonar systems

Active sensors are incorporated into a number of technologies, such as meteorology devices and self-driving cars, and use the echo from sound, radio or light waves to locate objects. But despite nearly a century of development, these active sensing technologies still fail to replicate the performance of sonars (sound waves) used in the biological world by dolphins and bats for echolocation.
To find ways to improve human-made active sensing, scientists worldwide study the sonar systems of bats and dolphins. During the Acoustical Society of America's 176th Meeting, held in conjunction with the Canadian Acoustical Association's 2018 Acoustics Week, Nov. 5-9, at the Victoria Conference Centre in Victoria, Canada, Laura Kloepper, assistant professor at Saint Mary's College in Notre Dame, Indiana, will compare bat and dolphin sonar systems, describing her work on how the two animals cope with acoustic interference. She'll use her findings to argue why bats have the superior system.
"I'm on Team Bat," said Kloepper. "But I'm going to be presenting dolphin work to argue why bats are better." She hopes her talk sparks a healthy debate between researchers of both animals.
Kloepper's talk is part of a special session devoted to bat and dolphin sonar systems. Several of the speakers in the session will appear in a press conference devoted to the subject.
