In work on the basis of one of the methods of nonlinear acoustics (method of successive approximations) is considered environment as a set of orthogonal plane layers. The analysis is conducted with the division generated total field into components parallel and orthogonal to the direction of its propagation. It is recognized as the primary distribution field distribution along the longitudinal direction with the introduction of the aperture factor and orthogonal to the introduction of the cross-aperture factor. It determines the range of changes of the parameters for biological environments in the case of the nonlinear interaction of acoustic waves in them.

Keywords: nonlinear interaction, quadratic nonlinearity, different layered media, immersion method, transverse aperture factor.
