Refrigerator abnormal sound monitoring method and device, refrigerator and storage medium

The invention relates to the technical field of intelligent household appliances, and discloses a method for monitoring abnormal sound of a refrigerator, and the refrigerator comprises a plurality of loads. The method comprises the steps that a load self-checking instruction of the refrigerator is responded; under the condition that the refrigerator is in the standby state, first environment volume is collected; under the condition that the plurality of loads are independently operated one by one, acquiring a second environment volume of operation of each load; and determining the abnormal sound condition of each load according to the first environment volume and the second environment volume. According to the method, the actual volume during operation of each load can be respectively obtained according to the first environment volume and the second environment volume. And then whether the actual volume of each load has abnormal sound is determined. In this way, abnormal sound conditions of multiple loads of
