Method and apparatus for a hearing assistance device using mems sensors

The present invention relates to a hearing assistance apparatus (100) adapted to be worn by a user having an ear and an ear canal (127), the apparatus for hearing assistance of the user comprising a housing (120, 240, 340, 440) comprising an earmold adapted to fit against the skin (125) of the user's ear canal (127), a microphone (144), for reception of sound and generating a sound signal, a signal processor (140) adapted to process the sound signal for hearing assistance using a signal processing algorithm, a micro electro-mechanical structure, MEMS, sensor (130) arranged in the housing (120, 240, 340, 440) and adapted to measure mechanical motion and provide a voltage waveform signal to the signal processor (140), the MEMS sensor mounted to the housing (120, 240, 340, 440) to receive structural vibrations from skin (125) of the user's ear canal (127), and a receiver (142) adapted to provide sound in the user's ear canal (127) using the signals from the signal processor (140), wherein the signal processor (140) is adapted to process the sound signal using the voltage waveform signal from the MEMS sensor (130) and the signal processing algorithm.
