The Sonitus Bone Conduction Device (BCD) is a bone conduction device for single-sided deafness (SSD). The Sonitus BCD consists of an Oral Appliance (OA), an external microphone component, worn behind the ear (BTE), a calibration interface cable and a PC-controlled calibration software for subject calibration. The Sonitus BCD picks up sounds from a microphone located within the ear canal of the deaf ear, capitalizing on the acoustics of the natural pinna and ear canal. The signal picked up by the microphone is then transmitted wirelessly to a removeable bone conduction oral appliance located on the upper molars. The oral appliance receives the acoustic signal from the BTE and applies an equivalent vibratory signal to the teeth that reaches the skull via bone conduction and routed transcranially to the contralateral cochlea.
