Abstract: PROBLEM TO BE SOLVED: To detect a failure of a machine by detecting and monitoring the state of an impulsive sound superimposed on a mechanical noise. SOLUTION: The mechanical noise is collected by a small microphone 1, and an analog acoustic signal is collected. Data are sampled at prescribed time intervals from the acoustic signal by an analog/digital converter 2, to thereby generate a digitalized acoustic signal. A time detection part 4 processes the acoustic signal by a filter, smoothes the data, and detects a generation time of the impulsive sound. A comparison data operation part 5 converts time series data including the impulsive sound having a specified generation time into a power spectrum, removes the influence of noises other than the impulsive sound, and holds it for a while in an operated value storage part 6. Thereafter, the similar processing is performed to operate the power spectrum at the time after elapse of a prescribed period or the like during a period of endurance.  A comparison determination part 7 compares it with the value held in the operated value storage part, and detects the failure by fluctuation of the value.
