Abstract: There is provided a noise reduction headset having multi-microphone and a noise reduction method. One embodiment of the headset includes a headband and headset bodies respectively connected to both ends of the headband, wherein the headset further includes a microprocessor and at least three microphones disposed on an outer surface of the headset body; the microprocessor is configured to select the microphone closest to a target sound source as a main microphone according to a comparison of sound signals picked up by respective microphones, select the microphone farthest from the main microphone as an auxiliary microphone according to a preset relative position of respective microphones, and execute a noise reduction algorithm by using a first sound signal picked up by the main microphone and a second sound signal picked up by the auxiliary microphone as inputs of the noise reduction algorithm so as to realize noise reduction. According to the embodiment, the noise reduction performance can be ensured under the condition that the user does not wear the headset normally.
