Application of leakage detection based on acoustic emission technology

The acoustic emission technology has high sensitivity and good stability, and is not affected by the condition of the specimen itself. Acoustic emission (AE) can be used to determine the damage of concrete structures and is an effective means of structural health monitoring. In this paper, wavelet analysis method is used to process the acoustic emission signal of underground engineering leakage, It achieves good filtering and signal extraction, By determining the time when the sound wave reaches the sensor, the positioning accuracy is improved and the location of leakage is better realized.
