Sonitus SoundBite

Sonitus Medical's SoundBite Hearing System is the world's first non-surgical
and removable hearing solution to use the well-established principle of bone
conduction to imperceptibly transmit sound via the teeth. It is intended to
help patients who are essentially deaf in one ear regain spatial hearing
ability and rejoin the conversation of life. Nearly invisible when worn, the
SoundBite system consists of an easy to insert and remove the in-the-mouth
hearing device - which is custom made to fit around the upper, left or right,
back teeth - and a small behind-the-ear microphone unit. No modifications to
the teeth are required.
