| description | The invention is applicable to the technical field of sweepers, and provides a sweeper noise reduction method which comprises the following steps: acquiring net value noise information of a sweeper fan in unit time, the net value noise information comprising a net value noise waveform; determining the frequency spectrum of the noise of each corresponding frequency band according to the net value noise waveform and a preset conversion algorithm; and reversely amplifying the frequency band noise meeting a preset frequency spectrum threshold by a preset multiplying power and sending the frequencyband noise to a loudspeaker. The embodiment of the invention further provides a sweeper noise reduction device, a sweeper and a computer readable storage medium. According to the sweeper noise reduction method provided by the embodiment of the invention, noise generated in the working process of the sweeper can be effectively reduced, noise pollution is reduced, and the use experience of a user is improved.
