Abstract
Provided are a noise cancellation method and apparatus, an electronic device, a noise cancellation earphone, and a storage medium. The method includes acquiring original sound source information; performing noise reduction (NR) processing on the original sound source information using active noise cancellation (ANC) to obtain first sound information and performing the NR processing on the original sound source information using environmental noise cancellation (ENC) to obtain second sound information; and mixing and adding the first sound information and the second sound information to obtain target sound information and playing the target sound information. In this method, the NR processing can be performed on the sound using the ANC and the ENC, thereby distinguishing environmental noise from human voice, improving the noise cancellation performance, and enabling a user to hear clearer sound.
