Tactical earphone control method and tactical earphone

Abstract

The invention provides a tactical earphone control method and a tactical earphone. The tactical earphone can be switched among a first mode, a second mode and a third mode. The method comprises the following steps: a feed-forward microphone collects ambient sound; under the condition that the tactical earphone is in the first mode, the processor processes first noise in the environment sound to generate first reverse noise which is the same as the first noise in frequency spectrum and opposite to the first noise in phase, and the loudspeaker plays the first reverse noise; under the condition that the tactical earphone is in the second mode, the processor separates the sound of the human voice frequency band from the environment sound, and the loudspeaker plays the sound of the human voicefrequency band; and under the condition that the tactical earphone is in the third mode, the processor amplifies the environment sound and then plays the environment sound through the loudspeaker. According to the invention, the tactical earphone has a noise reduction function, so that an individual soldier can hear an instruction more easily and clearly in a combat environment with more noise.
