ABSTRACT:
An implantable hearing aid transducer interface disposable between an implantable transducer and a mounting apparatus and having at least a portion that is displaceable in response to a predeterminable range of transducer movement. According to one aspect of the invention, the predeterminable range of transducer movement includes movement in response to a physiological movement of an auditory component that results in pressure on the implantable transducer. In this case, the compliant interface permits adaptive movement of the implantable transducer in response to the pressure to maintain a desired interface between the implantable transducer and an auditory component. According to another aspect, the predeterminable range of transducer movement may be transducer vibration resulting from an acoustic stimulation of an auditory component by the implantable transducer. In this case, the compliant interface reduces the transmission of transducer vibration over a feedback path to a microphone of a hearing aid.
