A cochlear implant auditory prosthesis corrects sensorineural deafness by generating stimulus signals to neurons connected to the auditory nerve in response to vibrations in the basilar membrane of the cochlea of the inner ear. The prosthesis comprises a plurality of transducer elements disposed along the length of the cochlea adjacent to the basilar membrane, whereby each transducer element responds to vibrations in the basilar membrane at the corresponding location of the respective transducer element. Each transducer element comprises a transducer for detecting the respective vibrations of the basilar membrane, and a signal processing element for generating a stimulus signal in response to the vibration. The frequency response and gain of each transducer element of the prosthesis can be tuned by a compact control unit to provide an ideal response for the user.
