METHOD AND APPARATUS FOR NOISE REDUCTION CONTROL USING MICROPHONE ARRAY

摘要

A method and an apparatus for noise reduction control using a microphone array are provided in the present invention, wherein the method includes the following steps: S1, collecting sound signals by the microphone array;S2, determining incidence angles of all the sound signals collected by the microphone array; S3, doing statistics of signal components according to the incidence angles; S4, controlling an adaptive filter according to the statistics results. The present invention utilizes the microphone array to obtain the spatial location information of the voice directly, fully takes advantage of the obtained location information to control the update and filtering of the adaptive filter more accurately, so as to eliminate the noise, promote the signal noise ratio, and protect the voice quality simultaneously.
