The work concerns diagnosis of the origins and development of early stages of defects based on information found in vibroacoustic signal. At the beginning the necessity of selection of diagnostic parameters dependent upon the amount of dissipated energy and related defect development is proven. Emphasizing the fact that defect development does not always lead to a significant growth of the vibroacoustic signal's power, the author has shown importance of analysis and modelling of low-energy defects.
