1. An abnormal sound diagnosis system for specifying a cause of abnormal sound in an apparatus that includes a plurality of operating units that perform a predetermined operation and a plurality of driving units that drive the plurality of operating units, the system comprising:
a determination unit configured to perform determination on occurrence of abnormal sound in a plurality of time periods, based on sound wave levels of sound occurring in the apparatus measured in the plurality of time periods;
an obtaining unit configured to obtain driving states of the plurality of driving units in the plurality of time periods; and
a specifying unit configured to specify a driving unit corresponding to abnormal sound that has occurred, from among the plurality of driving units, based on occurring states of abnormal sound determined by the determination unit, and the driving states obtained by the obtaining unit,
wherein the specifying unit compares the driving states and the occurring states obtained at different timings in the predetermined operation, thereby obtains a plurality of comparison results corresponding to the different timings, and specifies a driving unit corresponding to occurrence of abnormal sound based on the plurality of comparison results.
