The problem of the stochastic instability of dislocations in the field of a monochromatic acoustic wave was considered within the framework of classical mechanics. The critical sonic amplitude which determined the threshold for the motion of stochastic dislocations was obtained. An estimate was obtained for the time which was required for the separation of diffusive dislocations from point obstacles.
