Method and apparatus for detecting user activities from within a hearing assistance device using a vibration sensor
First Claim
1. A hearing assistance device, comprising:
- a first microphone configured to receive a sound and to create a sound signal relating to the sound;
a transducer configured to produce an output voltage related to motion, the transducer including a second microphone being an electret microphone;
a signal processor connected to the first microphone and the transducer, the signal processor configured to process the sound signal and the output voltage and to perform a vibration detection algorithm adapted to determine a correlation between the output voltage and each signature signal of predetermined signature signals characterizing activity types and adjust hearing assistance device settings for an activity type of the activity types detected from the output voltage in response the correlation exceeding a threshold, the activity types including at least one non-speech activity type; and
a housing adapted to house the signal processor.

Abstract
The present subject matter relates to method and apparatus for processing sound by a hearing assistance device. In one example, the present subject matter is an apparatus for processing sound for a hearing assistance device, comprising: a microphone adapted for reception of the sound and to create a sound signal relating to the sound; a transducer that produces an output voltage related to motion; a signal processor, connected to the microphone and the transducer, the signal processor adapted to process the sound signal and the output voltage, the signal processor performing a vibration detection algorithm adapted to adjust hearing assistance device settings for a detected activity; and a housing adapted to house the signal processor.
