@ABSTRACT = The influence of microplasticity caused by the motion 
of dislocation segments on the propagation of elastic vibrations in 
structural materials is considered. It is shown that the character 
of motion of a dislocation segment exerts its effect on the propagation 
velocity of an acoustic wave. This fact should be taken into account 
when nonstationary frequency-phase methods of measuring the physical 
parameters of a medium are used.
