Matching phases of microphones of hearing aid directional microphone involves matching second signal level to first by varying transition time of output signal from microphone without taking into account sound source position information

摘要

The method involves measuring or specifying (PSO) a first level of an omnidirectional signal (y1'(t)) of the directional microphone, measuring (PS) a second level of a directional signal (y1(t)) of the directional microphone and matching (A) the second level to the first level by varying the transition time of an output signal (x2) from one of the microphones (M2) of the directional microphone without taking into account sound source position information. An independent claim is also included for a device for matching phases of microphones of a hearing aid directional microphone.
