step S10, acquiring the operating frequency of a preset target mechanism in the air conditioner, and acquiring the environmental audio data of the environment where the indoor unit is located;
in this embodiment, after the air conditioner is powered on and starts to work, the operating frequency of the preset target mechanism in the air conditioner is acquired, because the noise generated when the air conditioner operates mainly comes from the fan and the compressor, and the sound generated when the indoor unit and the outdoor unit work is also audible indoors, the preset target mechanism can be set to be one or more of the outdoor fan, the indoor fan and the compressor, and can also be a mechanism which can generate noise in other operable processes in the air conditioner. The method comprises the steps that an audio collector can be arranged in an indoor unit of the air conditioner and used for collecting environmental audio data of the environment where the indoor unit is located, an audio collector externally arranged in the environment where the indoor unit is located can also be arranged, when the running frequency of a preset target mechanism of the air conditioner is obtained, the environmental audio data of the environment where the indoor unit is located are collected, whether the preset target mechanism generates noise or not can be further determined through analysis of the audio data, and therefore whether active noise reduction processing is conducted on the preset target mechanism or not can be judged.

After each acquisition, subsequent analysis is carried out, determining the matching audio corresponding to each frequency doubling frequency in the environmental data is that the matching audio corresponding to each frequency doubling frequency in the environmental audio of each preset time length is determined, namely the matching audio corresponding to each frequency doubling frequency is searched in the environmental audio data of each preset time length, a single amplitude value corresponding to each matching audio in the environmental audio data is determined after the matching audio is found, an evaluation value is further calculated according to a plurality of single amplitude values to obtain an actual amplitude value, specifically, the actual amplitude value is an average value of a plurality of single amplitude values corresponding to the single frequency doubling frequency, finally, the actual amplitude value is compared with the preset amplitude value, if the actual amplitude value is larger than the preset amplitude value, the sound loudness generated by a preset target mechanism in a period of time is larger, and the preset target mechanism needs to be actively controlled to enter a noise reduction mode, and carrying out active noise reduction processing.
