It is put forward that the abnormal noise of the bearing is a kind of transient pulses which can be illustrated by the time-frequency spectrogram. The parameters for evaluation of the abnormal noise of the rolling bearing are brought forward, which are based on the measurement and tests of the abnormal noise. At the same time, the preliminary statistics results are obtained.
