Abstract
The present subject matter relates to method and apparatus for detecting user activities within a hearing assistance device, and among other things, apparatus including a microphone for reception of sound and to generate a sound signal; an electret vibration sensor adapted to measure mechanical vibration and to produce a vibration signal; a signal processor, connected to the microphone and in communication with the electret vibration sensor, the signal processor adapted to process the sound signal and to process the vibration signal; and a housing adapted to house the signal processor. Variations provide a housing, microphone, and receiver in different configurations. In some variations wireless electronics are included and are used to communicate different signals. In some examples, the design is embodied in a variety of hearing aid configurations.
