Abstract
A method for reducing noise includes: obtaining a priori signal-to-noise ratio of air-bone integration, the priori signal-to-noise ratio of air-bone integration being obtained by integrating air conduction parameters of the current frame, bone conduction parameters of the current frame and air conduction noise parameters of the current frame; calculating a noise reduction gain according to the priori signal-to-noise ratio of air-bone integration; and performing noise reduction operation according to the noise reduction gain and the air conduction parameters of the current frame.
