New Device Aims to Stop Ringing in Your Ears

Tinnitus, or ringing in the ears, affects around 50 million Americans and requires about $2.26 billion annually in treatment costs. It is caused by damage to the ears by loud noises. University of Michigan engineers 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. The device is based on 15 years of research.
