Abstract:By using the sound source localization technology of microphone array widely used in the field of artificial intelligence,based on the time delay estimation(TDE),the generalized cross‑correlation (GCC)algorithm is adopted,and the phase transformation(PHAT)weighting function is introduced to suppress noise interference,so as to achieve fast and intelligent leakage detection of water supply pipelines.
