The paper deals with the possibly establishing a hierarchy of phonon mechanisms of dislocations' attenuation at the Debye temperature in the investigated crystal. For the first time, the reproduction technology of dislocation absorption's frequency spectra of ultrasound in crystals at a known Debye temperature was demonstrated, as well as an algorithm for switching from thermal to structural, dynamic, acoustic, optical and colorimetric characteristics of crystals. There were studied the influence of structural defects of a crystal, in particular, nodes of a dislocation grid and pinning centers in the dislocations of different physical nature on the proposed empirical regularities, and the expediency of their use for samples of ionic crystals with different mechanical states was also grounded.
