Interpretation of Acoustic Field Data for Leak Detection in Ductile Iron and Copper Water-Distribution Pipes

The acoustic emission (AE) method is becoming popular for detecting leaks in municipal water mains where leaks are identified and the locations are determined through the interpretation of measured acoustic signals without excavation or disruption of services. For the interpretation of signals, several parameters, such as the frequency band of signals, coherence between signals, and cross correlation between signals, are used. However, studies...
