摘要
The relations for calculation of soundproofing and the other acoustic characteristics of a planar construction units are presented, obtained from solving the combined problem of acousto-elasticity for a multilayered media. These relations form the basis of the developed technique that is embodied in the computational algorithms and software. The of this technique advantages are illustrated by several numerical examples. Reliability of the obtained results is verified by comparison with the experimental data, including those obtained by authors. The example of synthesis of the multilayered wall, providing the required soundproofing level, is presented.
