Do fish have ears? What is the nature of underwater hearing and how does it differ from hearing in the air? If humans are the evolutionary descendants of ocean creatures, do we retain any fishy traces in the way we hear the world? And what about all the noise we humans make in our oceans? If we want to save the planet, do we need to learn to listen like the fishes once again? Today we explore these questions with Marine biologist and bioacoustics expert Dr. Sophie Nedelec.

Nedelec has a PhD in bioacoustics and behavioral ecology from the University of Bristol. She is a Dorothy Hodgkin Fellow of the Royal Society and he's a senior research fellow at the University of Exeter. She researches underwater sound, sensory ecology, and human’s sonic impacts on the environment and sustainability.

Speaking of oceans, today marks a bit of a sea change here at Phantom Power: the addition of occasional “SOS” episodes on the Science of Sound with co-host Dr. Nathan Morehouse. Nate's an Associate Professor of Biological Sciences at the University of Cincinnati, where he also serves as the Director of the Institute for Research in Sensing (IRiS), an interdisciplinary research institute focused on sensing, perception, and sensor technology development through adventurous integration of insights from the sciences, engineering, humanities, and arts.
