Estimating the spectrum of leak noise in buried plastic water distribution pipes using acoustic or vibration measurements remote from the leak
Mechanical Systems and Signal Processing(2021)
Abstract
•A method to estimate the spectrum of leak noise at source is presented.•The proposed method is applied to data from three test sites.•The effects of using hydrophones or accelerometers on the estimation of the leak noise spectrum are highlighted.
