Abstract
Method for acoustically locating leaks in underground or aboveground piping systems, in which at least two noise data loggers receiving the leak noise and being arranged in mutual distance from one another are brought in physical contact with the piping system to be examined and measure simultaneously the noise level (dB) and the frequency of a leak, whereas both measured values of frequency and noise level are combined in a single value (ESA), whereas the ESA value is calculated from the decimal logarithm of the frequency of the leak noise multiplied with the logarithmic level value of the leak noise multiplied with a constant factor.
