Have you ever heard a mysterious "ringing" in your ears? This disorder, called Tinnitus, affects an estimated 50 million Americans -- and requires around $2.26 billion annually in treatment costs. It is caused by damage to the ears by loud noises, and the problem is growing in people under the age of 20 who are using earbuds and mp3 players on a regular basis.

Researchers at the University of Michigan are working on a device to treat the disorder, which targets the nerves in the jaw and face with sound and electrical stimulation to reduce the hyperactivity in the nerves that can lead to Tinnitus.
