Claim 5:
6. The method according to claim 1, wherein the filtering the coherent noise signal from the first sound signal and the second sound signal when the coherent noise signal is determined to be included in the first sound signal and the second sound signal to acquire and output a target sound signal at a corresponding signal processing time comprises:
taking the first sound signal and the second sound signal as one-way preprocessed sound signal respectively, and filtering out the coherent noise signal at the current signal processing time from the preprocessed sound signal to obtain the first sound signal and the second sound signal with coherent noise filtered;
performing beamforming processing on the first sound signal and the second sound signal with coherent noise filtered based on the current signal processing time to obtain the target sound signal.
