Document Type and Number:
WIPO Patent Application WO/2017/206488
Kind Code:
A1
Abstract:
Disclosed are a noise reduction method and apparatus for self-adaptively adjusting a noise reduction gain, and a noise reduction earphone. The method comprises: receiving a voice signal collected by a microphone mounted on an earphone receiver, and taking same as a noise signal; determining, according to a current sound intensity of the noise signal, a current noise grade of an external environment; setting a current noise reduction gain value corresponding to the current noise grade; and performing, according to the current noise reduction gain value, noise reduction processing on the noise signal. In the present invention, by setting a noise reduction gain value corresponding to a current noise grade according to a current noise grade of an external environment, the noise reduction earphone can self-adaptively adjusts a noise reduction gain, thereby effectively improving the user experience.
