1. A method for implanting a magnetic disk means on the mastoid bone to enhance sound transmission, the method comprising the steps of:
- (1) making an incision behind the ear and exposing the linea temporalis of the temporal bone;
(2) drilling a hole in a substantially flat surface of the temporal bone;
(3) tapping the drilled hole to provide internal screw threads therein;
(4) attaching a magnetic disk means having a flat lower surface to the temporal bone by a screw means threaded into the tapped hole of step (3);
(5) tightening the screw means to cause the flat lower surface of the magnetic disk means to lie snugly against the flat surface of the temporal bone; and
(6) closing the incision with the magnetic disk means implanted abutting against the temporal bone.

7. A method for enhancing hearing comprising the steps of:
-
making an incision and exposing a portion of patient'"'"'s skull; subcutaneously implanting into the exposed skull portion a first member including a magnetic portion and capable of receiving electromagnetic signals and generating vibrations; securing the first member in contact with and to the skull portion; closing the incision; magnetically securing a second member capable of transmitting electromagnetic signals to the magnetic portion of the first member; and transmitting electromagnet signals transcutaneously from the first member to the second member and generating vibrations in the skull portion in contact with the first member which are conducted to the patient'"'"'s inner ear. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)
