A method of noise reduction, which is applied to an electronic device. The electronic device includes a first sound collector and a second sound collector, installation positions of the first sound collector and the second sound collectors are different; the method includes: determining a desired sound signal and an interference sound signal based on a first sound signal collected by the first sound collector and a second sound signal collected by the second sound collector (S); obtaining a third sound signal by performing coherent noise elimination processing on the desired sound signal based on the interfering sound signal (S); and then obtaining a target sound signal by performing incoherent noise suppression processing on the third sound signal based on a probability of existence of a speech in the third sound signal (S).
