Abstract

A hearing assistance system (200) senses sound vibrations of an auditory element in the middle ear (35), and provides a stimulus to an auditory sensory element. The vibrations are received through the tympanic membrane (30), and sensed at the tympanic membrane (30), malleus (40), incus (45), or other auditory element. A capacitive sensor (260) is mechanically or magnetically coupled to a vibrating auditory element, such as the malleus (40), and time-varying capacitance values resulting from the vibrations are detected. One embodiment allows pivotable mechanical coupling of the capacitive sensor (260) to at least one of the auditory element and a carrier (220) secured within the middle ear (35). A resulting electrical output signal is provided to the output stimulator (215) for assisting hearing.
