Noise cancellation method, device, electronic equipment, earphone and storage medium

Abstract

This invention discloses a noise cancellation method, apparatus, electronic device, headphones, and storage medium. The method includes: acquiring original sound source information; performing noise reduction processing on the original sound source information using ANC to obtain a first sound message; and simultaneously performing noise reduction processing on the original sound source information using ENC to obtain a second sound message; performing noise reduction processing on the original sound source information using ANC to obtain the first sound message includes: passing the original sound source information through a phase inverter to perform noise phase inversion processing to obtain an inverted wave signal; performing noise cancellation on the original sound source information based on the inverted wave signal to obtain the first sound message; mixing and adding the first sound message and the second sound message to obtain a target sound message, and playing the target sound message. Acquiring the original sound source information includes: acquiring the sound signal of the original sound source through a microphone and converting the sound signal of the original sound source into an electrical signal of the original sound source; converting the electrical signal of the original sound source into a digital signal of the original sound source through an analog-to-digital converter, and using the digital signal of the original sound source as the original sound source information. This method can perform ANC and ENC noise reduction on sound, distinguish between environmental noise and human voice, improve noise cancellation performance, and allow users to hear clearer sound.
