Non-destructive testing. Methods for absolute calibration of acoustic emission transducers by the reciprocity technique Ingestion-build-232773 An optical instrument is a1 Scope This Technical Report describes the method of three transducer calibration for calibrating frequency responses of absolute sensitivity by means of a reciprocity technique using three reversible acoustic emission transducers of the same kind, the method of two transducer calibration for calibrating frequency responses of reception sensitivity of an optional acoustic emission transducer by using one acoustic emission transducer, the transmission
