Abstract Diagnostics of defects is the first step towards their "healing" - partial or complete elimination of the effect of defects on the stress-strain state of the structure. This article considers the "healing" of cavity defects by filling with various materials. Evaluation of the effectiveness of such healing is carried out according to vibroacoustic criteria using the examples of annular defects in a rod and a small hole in a plate.
