    The study of the acoustic properties of a pipeline section was conducted in accordance with standards regulating acoustic emission testing of pressure vessels and related activities. To achieve this objective, an experiment was performed to emit acoustic signals on the surface of the pipeline section. Based on the test results and assessment, corrective measures were prescribed to restore the pipeline to optimal operational condition. A multi-channel acoustic system was utilized to carry out the tests on the pipeline section.
