摘要：A method and device detect a position of a pulsed mechanical effect on a plantcomponent. An operating noise in the plant component is continuously recorded bysensors which are arranged on the plant component and converted by the above into ameasured signal. The measured signals of the sensors undergo a transformation in a firsttime window. A first evaluation function is derived from a plurality of first transformationsdetermined in this manner, the evaluation functions display an appearance of the pulsedmechanical effect. Accordingly, when detecting an effect following the second shortertime window having the same algorithms, second transformed and respectively, secondevaluation functions are derived, from which, respectively, one time point is determined.Wherein the sound signal produced by the effect impacts upon the sensor. From there,running time differences produced between the sensors can be exactly reconstructed onthe position of the effect.
