ABSTRACT:
In a hearing system, a transmitting coil is positioned on the promontory centered medial to the umbo of the tympanic membrane while securing the magnet to a surface of said tympanic membrane or to the manubrium of the malleus. The system does not require the permanent placement of components in the auditory canal which would otherwise interfere with normal hearing when the system is not in use.
