I. Spill detection
Sound detection
The principle of acoustics is to produce “spill noise” with different frequencies when the water flows from the porosity of the pipe, the frequency of which is determined by the water pressure, the size and shape of the leak, the piping material and the land filling material. Indirect sound detection using ground microphones can be used to detect low-frequency leak noise through the ground. However, as this is also the frequency segment of footsteps and traffic noise, testing by experienced inspectors is required to achieve satisfactory results. While leaks may be found at the point where the sound is loud, excessive noise can make direct and indirect sound detection more difficult, with wind weather, traffic noise, large traffic and pumps causing problems in detection, so sound detection is effective at night。
