A New Party Trick: A Hearing Aid That Reads Minds

You’re at a party. Maybe it’s a New Year’s Eve party. Music is playing, people are celebrating. Somehow, in the middle of all this noise, you can pick out the voice of the person standing next to you.

Nima Mesgarani, PhD, a neuroengineer at Columbia’s Zuckerman Institute, is studying how your brain does this — and using this knowledge to build a better hearing aid that reads your mind.
