deafness

National Institutes of Health

Engineers at the University of Washington have developed a way for some deaf people to enjoy music. The findings could help people with cochlear implants, a bionic inner ear that allows deaf or hearing-impaired people to hear speech, albeit in kind of a robot voice.

Cochlear implants can be a lifesaver for people without hearing, but when it comes to music, this very practical device can’t carry a tune to save its life.

The implants simply aren’t sensitive to pitch and what’s called timbre—the qualities of a sound that make, say, a guitar sound different from a harp.
