Abstract

The invention provides a noise reduction method and device of an earphone, electronic equipment and a storage medium, and relates to the technical field of audio processing, in particular to the technical field of voice processing, voice recognition and the like. According to the specific implementation scheme, the correlation between sound signals collected by two microphones in the earphone is obtained, and the two microphones comprise a feed-forward microphone and a call microphone; acquiring first energy of a sound signal acquired by a feed-forward microphone; determining a spectrum centroid of the sound spectrum according to the sound signal; performing wind noise detection on the earphone according to the correlation, the first energy and the spectral centroid; and performing active noise reduction on the earphone in response to detection of existence of the wind noise. Therefore, the influence of the correlation, the energy and the spectral centroid on noise detection is comprehensively considered, the detection of the earphone on the low-frequency noise can be improved by introducing the spectral centroid, and the situation that the active noise reduction effect is influenced due to the fact that the correlation of the low-frequency signal is low and the low-frequency noise is misjudged is prevented.

Description

technical field [0001] The present disclosure relates to the technical field of audio processing, specifically to the technical field of voice processing, voice recognition and other technical fields, and in particular to a noise reduction method and device for earphones, electronic equipment and a storage medium. Background technique [0002] Active Noise Cancellation (Active Noise Cancellation, ANC) is a key technology in the current development of Bluetooth headsets. It can make it easier for users to hear the content of the headset in a noisy environment, and improve the experience of headset users. Protect the user's hearing to a certain extent. [0003] However, among the many noises, wind noise is a relatively common type of noise, which will seriously affect the user's sensory experience when using headphones, and many headphones will even amplify wind noise. Contents of the invention [0004] The disclosure provides a noise reduction method, device, electronic eq...
