The methods of the quantitative study of interference wave fields in thin-layered elastic media are developed. The problems for the simplest thin-layered media are formulated, exact mathematical solutions of them are given in the Fourier type. The methods of the quantitative estimation of the wave fields in the sufficiently low-frequency band of their spectrum are discussed. The problems of the quantitative studing the roots of dispersion equations and the numerical integration in the complex plane are considered in detail.
