Abstract
A sound diagnostic system includes an image forming apparatus and an information processing apparatus. The image forming apparatus includes operating portions, a sound collector for collecting a sonic wave, an acquiring portion, in each of a plurality of time sections when the sonic wave is collected by the sound collector, for acquiring a data including sonic wave level and an operating state of the operating portions. The information processing apparatus includes a generator for generating a threshold by adding a predetermined value to a first sonic wave level based on the sonic wave in a first period. The information processing apparatus determines a cause of an abnormal sound by comparing a second sonic wave level based on the sonic wave in a second period after the first period and the threshold. The predetermined value is set so as to be smaller as the first sonic wave level is larger.
