Reducing Background Noise in Hearing Devices

How a new noise-reduction algorithm suppresses babble in cochlear implants and hearing aids.

People who wear cochlear implants and hearing aids are often faced with the challenge of distinguishing the words of the speaker they are trying to listen to from "babble" - the combined noise of other speakers in the background.

However, a research team at New York University (NYU) has created a solution - an algorithm that separates the speaker's voice from the noise of background talkers.
