Abstract: Hearing with two ears allows us the ability to pinpoint the location of a sound source – an ability we rarely think about but use all the time, especially when listening to one sound source in the midst of a constant barrage of other sources and reflections. In this talk, I will discuss how sound source location is encoded in the brain via neural circuits that compare sound waves between the two ears. I will present evidence that sound location is encoded in neural activity in different ways for low- and high-frequency sounds, and discuss how localizing in everyday, cluttered acoustic environments may be accomplished.
