Abstract In this paper the problem about nonlinear interaction of elastic waves with different temporal scales surveyed in common statement. From Khokhlov-Zabolotskaia equation it is possible to receive the partial equations describing evolution of each component of a wave field. One-sided character of such interaction is shown. Influence of a low-frequency wave on high-frequency is exhibited primarily in amplitude dependence of a high-frequency wave phase velocity variation.
