ACTIVE NOISE REDUCTION METHOD AND SYSTEM, AND RELATED APPARATUS

Disclosed in the present application are an active noise reduction method and system, and a related apparatus. The method is applied in an environment to be subjected to noise reduction, and said environment includes a plurality of loudspeakers and at least one microphone. The method comprises: for each of at least one microphone, acquiring a first loudspeaker set corresponding to the microphone, wherein the first loudspeaker set includes at least some loudspeakers, and a transmission error between the at least some loudspeakers and the microphone is not greater than a threshold value; obtaining the current audio signals and a mixed audio signal, which are collected by the microphone, wherein the current audio signals are all audio signals that are received by the microphone, and the mixed audio signal is formed by means of original audio signals, which are sent by the loudspeakers in the first loudspeaker set and are transmitted to the microphone; obtaining an error audio signal on the basis of the current a
