Listening to Moving Fluids: How Sound Waves Reveal Hidden Worlds
About this episode
This episode discusses a new approach to understanding fluid movement using sound waves instead of visual techniques.
It would be difficult to understand the movement of water in a murky lake, or the swirling air inside a sealed chamber, without being able to see inside. For decades, scientists have relied on clever tricks to peer into such opaque environments, often adding particles or using optical techniques. But what if the fluid is too dark, too enclosed, or too delicate for those methods? A new approach, developed by researchers Lennart Kira and Dr. Jerome Noir of ETH Zurich, offers a compelling answer. It listens instead of looks.
