The paper introduces a kind of sonic method by which frequency of impacter is measured. Recording software drives computer collect sound, convert A/D, store and play sound etc., software processing sound open sound file saved in the form of oscillogram to let user identify number of crest and corresponding time, thus frequency can be worked out. The result of analogue test shows that frequency of impacter measured by sonic method consists with actual frequency and the method is feasible.
