Kind Code:
A1
Abstract:
Disclosed are a method and system for detecting a state of a bone conduction hearing device. A bone conduction hearing device at least comprises a microphone, a loudspeaker, a feedback analysis unit, and a signal processing unit. The method comprises: a loudspeaker generating a third sound on the basis of a first signal, wherein the first signal is generated by a signal processing unit; a microphone receiving the third sound and generating a feedback signal; a feedback analysis unit determining, on the basis of the feedback signal of the microphone and the first signal, a feedback path transmission function from the loudspeaker to the microphone of a bone conduction hearing device; acquiring at least one preset feedback path transmission function; comparing the feedback path transmission function with the at least one preset feedback path transmission function; and the signal processing unit determining a state of the bone conduction hearing device according to a comparison result.
