1. A noise cancellation method, comprising:
acquiring original sound source information; and
performing noise reduction (NR) processing on the original sound source information using active noise cancellation (ANC) to obtain first sound information and performing NR processing on the original sound source information using environmental noise cancellation (ENC) to obtain second sound information;
wherein performing the NR processing on the original sound source information using the ANC to obtain the first sound information comprises:
performing noise phase inversion processing on the original sound source information through a phase inverter to obtain an inverted wave signal;
performing noise cancellation on the original sound source information according to the inverted wave signal to obtain the first 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;
wherein performing the NR processing on the original sound source information using the ENC to obtain the second sound information comprises:
separating human voice from environmental noise in the original sound source information through a software NR algorithm and retaining a human voice signal; and
performing enhancement processing on the human voice signal to obtain the second sound information;
wherein enhancing the human voice signal to obtain the second sound information comprises:
performing at least one of audio enhancement processing or volume enhancement processing on the human voice signal to obtain the second sound information; and
wherein the human voice is separated from the environmental noise in the original sound source information through the software NR algorithm within 0 to 30 milliseconds and the human voice signal is retained.
