New Study Reveals How Movement Changes Your Hearing

featured 15894

When we want to listen closely to someone, the first thing we do is stop talking. The second is to hold still. Those quieting behaviors improve hearing by preventing noise from our own movements from masking important sounds. That same relationship between movement and hearing exists inside the brain. For years, indirect evidence has hinted … Read more
