Abstract:
An abnormality detecting device includes a memory, and a processor coupled to the memory and configured to: detect an envelope of an audio signal indicating a periodic sound emitted by a target object and a periodic sound emitted by another object; execute time-to-frequency conversion on the envelope to calculate a frequency spectrum of the audio signal; and determine whether or not the target object has an abnormality, based on a frequency component included in the frequency spectrum and corresponding to a time interval between time points when the sound is emitted by the target object.

Claim (Index 3):
The abnormality detecting device according to  claim 2 ,\n wherein the processor is further configured to execute time-to-frequency conversion on the envelope in a first time region in which the sound emitted by the target object and the sound emitted by the other object are included in the audio signal so as to calculate the frequency spectrum, and execute time-to-frequency conversion on the envelope in a second time region in which the sound emitted by the target object is included and the sound emitted by the other object is not included in the audio signal so as to calculate a second frequency spectrum, and wherein the processor is further configured to detect multiple peaks of the second frequency spectrum, calculate, for each of combinations, each of which includes two peaks among the multiple peaks, a second ratio of a frequency corresponding to one of two peaks included in the combination to a frequency corresponding to the other of the two peaks included in the combination, and estimate, as the predetermined number of blades of the rotating device, a ratio that is among the ratios of the frequencies corresponding to the peaks, detected from the frequency spectrum, of the combinations and matches any of the second ratios of the frequencies corresponding to the peaks, detected from the second frequency spectrum, of the combinations.
