Why do we have two ears?

Binaural hearing refers to being able to integrate information that the brain receives from the two ears. Binaural hearing is known to help us with the ability to listen in noisy, complex auditory environments, and to localize sound sources.

In the Litovsky lab, we study binaural hearing in persons who have normal hearing and in persons who are deaf and use cochlear implants (CIs). We are interested in whether CI users can benefit from having two (bilateral) CIs and whether, for children, having bilateral CIs at a young age offers unique advantages.
