Acoustical characteristics of leak signals in plastic water distribution pipes
Acoustical characteristics of leak signals in plastic pipes were investigated in this study for several types of leaks simulated under controlled conditions at an experimental site. The investigation included the characterization of frequency content of sound or vibration signals as a function of leak type, flow rate, pipe pressure and season, the determination of the attenuation rate, and the variation of propagation velocity with frequency. The information presented in this paper for the acoustic characteristics of leak signals will help leak detection professionals in the selection of appropriate instrumentation, the design of appropriate measurement procedures, and in the case of propagation velocity, in accurately locating leaks using the cross-correlation method.
