The invention relates to a method for improving the hearing of a hearing-impaired subject. If the subject is anatomically normal he has a tympanic membrane intended for generating mechanical tympanic vibration in response to sound waves impinging thereon. Said method comprises the steps of: interrupting the ossicular chain to preclude transmission of mechanical vibrations between the tympanic membrane and inner ear of a subject; and, surgically interposing an implant comprising input and output transducer means for mediating mechanical/ electrical signals, having controlled amplification characateristics, within the interrupted ossicular chain to bridge the interruption therein and form an independent link between said tympanic membrane and said inner ear. |
