Abstract
Embodiments of the present disclosure provide a noise reduction method, the method includes: obtaining an acceleration signal of a mobile terminal when an audio output device is in a working state; determining, according to the acceleration signal, a vibration waveform of the mobile terminal when the mobile terminal vibrates; inverting the determined vibration waveform to obtain a noise reduction signal; and superimposing the noise reduction signal onto to-be-output audio of the audio output device. Therefore, noise generated by skeleton vibration is diminished or eliminated, so as to improve an effect of listening, by a person, to audio.
