Method and apparatus for hearing assistance device using MEMS sensors

摘要

A hearing assistance device adapted to be worn by a user having an ear and an ear canal, comprising: an earmold; and a micro electro-mechanical structure (MEMS) sensor in the earmold, the MEMS sensor configured to detect translational acceleration in three dimensions, the MEMS sensor oriented such that a relative z component is approximately parallel with a relatively-central axis of the ear canal, and such that relative x and y components define a plane that is relatively perpendicular to the surface of the earmold in the immediate vicinity of the ear canal tip.
