Abstract: Noise reduction method and device are provided. The method includes: obtaining different audio signals respectively collected by two audio collection devices, where one of the two audio collection devices has a specific positional relationship with an effective audio source; at least according to the different audio signals respectively collected by the two audio collection devices, determining effective signals corresponding to the effective audio source and noise signals corresponding to a noise source and obtaining determination results; and performing a noise reduction process on the audio signals collected by at least one of the two audio collection devices to retain the effective signals and reduce the noise signals, according to the determination results.
