Study finds human ear muscles move when focusing on listening, possibly indicating effort.

A study from Saarland University found that humans still have active auricular muscles that move slightly when we focus on listening, especially in challenging sound environments. These muscles, once used to move ears, are now vestigial but may indicate listening effort. The study suggests these muscle activities could offer an objective way to measure how hard we are listening, though more research is needed to understand their practical applications.
