ABSTRACT:
A method and apparatus for improving a frequency response of a piezoelectric input or output transducer in an implantable hearing system. Multiple input or multiple output transducers obtain optimized mechanical-to-electrical or electrical-to-mechanical frequency response. Output mechanical coupling is directly to the inner ear, or through an ossicular element such as the malleus, stapes, or incus. Input mechanical vibrations are obtained from an auditory element such as the tympanic membrane, malleus, or incus. Substantially nonidentical frequency responses are obtained such as using transducers of different dimensions, different number of transducer elements, different material properties, different mounting techniques, or different auditory elements for coupling.
