Abstract

PURPOSE: To correctly obtain the amplitude distribution of cracking sound signal using a device of inexpensive construction by detecting the amplitude of the isolated wave of detected cracking sound signal to discriminate its amplitude.
CONSTITUTION: A cracking sound signal is detected by a senser 11, and is supplied to band-pass filters 13 and 14 through an amplifier 12. The outputs of the band- pass filters 13 and 14 are supplied to maximum amplitude detectors 15 and 16 respectively. The outputs of the maximum amplitude detectors 15 and 16 are supplied to amplitude discriminators 11W1n and 21W2n, and the outputs of discriminators 11W1n and 21W2n are supplied to computers 31W3n and 41W4n. The contents of computation of these computers 31W4n are printed by a printer 24.
