FIELD: physics.
SUBSTANCE: object acoustic properties are pre-examined and primary transducers are installed. Acoustic-emission hardware serviceability is checked to calibrate channels. Controlled object is loaded to test pressure to register acoustic emission signals exceeding preset thresholds to determine signal parameters to allow determining coordinates of developing defects therefrom and deciding on their danger. Note here that in loading reservoir additionally measured is mean square signal amplitude in equal time intervals for all primary transducers for which thresholds are set for every next time interval and through defects are defined.
EFFECT: higher accuracy and validity of through defect detection.
