The diamylose gram noise reduction system and noise-reduction method of a kind of earphone

The present invention provides a kind of diamylose gram noise-reduction method of earphone, and methods described includes：Main Mike gathers voice signal, and the voice signal of collection is delivered into Voice Activity Detection module voice signal is detected；Voice signal is delivered into noise parameter computing module, while aids in Mike to gather environment sound signal, and environment sound signal is delivered into noise parameter computing module；Noise parameter computing module calculates noise suppressed intensity；Voice signal and environment sound signal deliver to the noise suppression module；Noise suppression module carries out noise suppressed processing by voice signal and environment sound signal, and by the signal output after processing.The present invention is suppressed on the basis of active noise reduction by the noise for aiding in Mike's collection ambient noise to converse main Mike, while effectively suppressing stationary noise, the nonstationary noise in filtering environmental.
