Abstract
An approach to the evaluation of the sensitivity of an active vibroacoustic detection system to local changes of physical environmental parameters around main pipelines is suggested. The results of calculations of the amplitude increment for recorded signals, which depend on the length of the considered type of defect, are given. The promise of the vibroacoustic technique for the detection of predecessors of emergencies during pipeline transport was determined.
