Abstract :
Acoustic emission (AE) is defined, and the various systems for acoustic emission testing are discussed. Focus is placed on the four types of AE sensors: piezoelectric, electromagnetic, capacitive and optical. Key parameters are discussed to given an insight into the data available during an AE inspection. Calibration of the test equipment is discussed along with AE applications. Factors relating to system selection are outlined
