Annotations languages:

In article the general expressions for finding of one-dimensional cumulants and cumulant coefficients of acoustic leak signals are received. It is carried out the analysis of influence of parameters model of leak signals on values of cumulant coefficients. It is established that leak signals at an exponential form of impulses and exponential distribution of their amplitudes have gamma distribution of instant values.
Keywords: detection of leaks in the pipeline, acoustic contact leak detection, acoustic leak signal, cumulant functions
