The SoundBite Hearing System by Sonitus Medical consists of two main components; a behind the ear (BTE) microphone unit and an in the mouth (ITM) hearing device. Accessories include a system charger and programming software. The BTE uses a digital signal processor to process the sound and a wireless chip to transmit the signals to the hearing device worn in the mouth. The ITM hearing device in turn creates imperceptible vibrations using a piezoelectric actuator that are sent via the teeth, through the skull bones, and ultimately to the cochleae.
