Abstract
The present invention is directed to a contact hearing system utilizing an emitter adapted to emit light and a contact hearing device adapted to receive the emitted light and convert that light into sound by mechanical manipulation of a subjects ear drum. In the present invention the emitter may utilize multiple light sources and the multiple light sources may be passed through at least one diffuser in order to generate an emitted light having a broader angle of incidence with little or no loss in received power as measured by a photodetector on the contact hearing device when the contact hearing device is positioned on a subject's tympanic membrane and the emitter is positioned in the subject's ear canal.
