Sound diagnosis system, sound diagnosis method, and sound diagnosis program

A sound diagnosis method comprising:

• acquiring a sound emitted by a device;
• analyzing a sampling result of the sound and calculating a total sound pressure of a sound of each frequency included in each timing of the sampling result;
• extracting a plurality of peak timings from the total sound pressure;
• clustering the plurality of peak timings;
• identifying a cycle of a sound included in each cluster based on the frequency and/or each total sound pressure;
• identifying at least one component that emits a sound having a cycle close to any of cycles of sounds included in each cluster;
• and
• displaying the at least one identified component.

A non-transitory recording medium storing a computer readable sound diagnosis program causing a computer to execute:

• acquiring a sound emitted by a device;
• analyzing a sampling result of the sound and calculating a total sound pressure of a sound of each frequency included in each timing of the sampling result;
• extracting a plurality of peak timings from the total sound pressure;
• clustering the plurality of peak timings;
• identifying a cycle of a sound included in each cluster based on the frequency and/or each total sound pressure;
• identifying at least one component that emits a sound having a cycle close to any of cycles of sounds included in each cluster;
• and
• displaying the at least one identified component.
