Zusammenfassung:The disclosure relates to a method of and system for monitoring the state of a device that includes a rotatable component. The system includes a structure-borne noise meter and an evaluation device. The evaluation device ascertains a time range feature for a frequency band, compares the time range feature with at least one threshold to determine a time range feature state, and determines the state of the device based on the time range feature state.
