A frequency reverberation method applied for analysis of sound field in rooms with absorbers considering given absorbers characteristics is discussed. Results of analytical investigation of multilayer absorbers are given. A method for synthesis of a construction characterized by heterogeneous material is presented. It is shown that wave resistance changes toward direction of sound wave propagation. Method of calculation of optimal sound-absorption system is developed. Proposed method allows finding out the most efficient construction characterized by minimal weight and dimensions.
