and locating pipeline damages without decommissioning of pipelines. Each of them has its own implementation means.Analysis of modern methods of detecting and locating leaks has shown that acoustic contact methods of controlling pipeline leakage have great potential. However, their application is often accompanied by significant errors in leak detection. This is caused by the design of the test object which is not always simple, ambiguity of physics of leakage signal formation in through defects of the test object and presence of interferences. Interference is caused by the
