A DEVICE FOR THE ACTIVATION OF AN APPARATUS FOR MEASURING ACOUSTIC EMISSION BY DETECTION OF BACKGROUND NOISE Abstract of the Disclosure An apparatus for measuring acoustic emission is activated only at critical periods which are determined by detection of the background noise from a reference level. An acoustic emission transducer continuously transmits a signal to a detection circuit which delivers the top modulation envelope of the background noise to a comparator at a reference level delivered by a control unit. When the mean level of the background noise exceeds the reference level, the comparator delivers a signal which activates the input/output assembly of the measuring apparatus. -1-
