Abstract

The invention discloses an earphone noise reduction method and an earphone noise reduction device, which are used for improving the noise reduction effect. The earphone noise reduction method providedby the embodiment of the invention is applied to the earphone, the earphone comprises a main microphone, an auxiliary microphone and a bone conduction microphone, and in the earphone noise reductionmethod, environmental noise is acquired through the auxiliary microphone, and the environmental noise is processed to obtain an environmental noise value. When the ambient noise value is greater thana first ambient noise threshold and less than a second ambient noise threshold, a certain ambient noise is indicated, for this purpose, a first human voice signal is acquired through the bone conduction microphone, a first audio signal is acquired through the main microphone, and the first audio signal comprises a second human voice signal and an ambient sound signal. Then, superposing the first human voice signal and the second human voice signal to obtain a target human voice signal; according to the mode, the bone conduction microphone is used for obtaining the human voice, so that the human voice signal is enhanced, the proportion of environmental noise is reduced, and the noise reduction effect is improved.

Description

Technical field [0001] The present invention relates to the technical field of audio processing, and in particular to an earphone noise reduction method and earphone noise reduction device. Background technique [0002] When the earphone acquires the human voice signal, it often acquires environmental noise together, which affects the user's listening effect on the voice acquired by the earphone. For this reason, the audio signal obtained by the earphone needs to be processed for noise reduction. [0003] The existing noise reduction processing solution is to use two ordinary microphones on the headset, and the active noise reduction processing is realized through the two microphones. Such a scheme has a poor noise reduction effect in a scene with high environmental noise. Summary of the invention [0004] The purpose of the present invention is to provide an earphone noise reduction method and earphone noise reduction device, which are used to improve the noise reduction effect. ...
