Abstract: Inverse problems of sound active minimization in a two-layer regular waveguide are formulated. For the solution of these problems the algorithm is developed earlier for the solution of similar problems in an ideal single-layered waveguide is modified. Results of the numerical experiments are discussed.

Key words: two-layer waveguide, inverse problem, active minimization of a sound, numerical algorithm, numerical experiment.
