A method and system for fitting and adjusting the operation of an acoustic hearing prosthesis or a hybrid electric and acoustic hearing prosthesis. A graphic user interface allows for the acoustic and electric fitting parameters to be viewed and adjusted in a comparable way. The method further allows for the parameters for acoustic stimulation of the acoustic channels to be adjusted in response to behavioral or objective measurement of response to known stimuli, so as to achieve a desired response curve.

A hearing prosthesis including an actuator. The actuator includes a material that deforms in response to an electrical signal and that is adapted to, upon implantation in a recipient, transmit vibrations representative of a sound signal to an organ of the recipient, wherein the material is at least partially exposed to at least one of body tissue and fluid of the recipient.

An implanted microphone is provided that allows for isolating an acoustic response of the microphone from vibration induced acceleration responses of the microphone. The present invention measures the relative motion between a microphone diaphragm, which is responsive to pressure variations in overlying media caused by acoustic forces and acceleration forces, and a cancellation element that is compliantly mounted within a housing of the microphone, which moves primarily in response to acceleration forces. When the microphone and cancellation element move substantially in unison to acceleration forces, relative movement between these elements corresponds to the acoustic response of the microphone diaphragm. This relative movement may be directly measured using various optical measuring systems.
