INFLUENCE OF ACOUSTIC-ELECTRONIC CHANNEL ON ACOUSTIC EMISSION HIT PARAMETERS
(pp. 14-22)

Abstract. The paper deals with the influence of acoustic emission (AE) signal propagation channel on the parameters of these signals, which are used to judge the object state. It is shown that the acoustic channel, which includes the testing object and the acoustic emission transducer, has a significant influence on the parameters of AE signals. This must be taken into account, both in the interpretation of signals and in the calibration of acoustic emission transducers. Specific examples of degradation of AE signal parameters during the passage of acoustic-electronic channels are shown.

Keywords: acoustic emission, acoustic channel, pulse, signal parameters.
