ABSTRACT:
A hearing system comprises a shell having an open inner chamber. An input transducer and a transmitter assembly are disposed in the open inner chamber. The transmitter has a frequency response bandwidth in a 6 kHz to 20 kHz range, and the open chamber has an end adjacent a patient's tympanic membrane with one or more openings that allow the ambient sound to pass through the chamber and directly reach the middle ear of the user.
