Acoustic bulletin, Vol. 12 ¹ 2, (2009) |
| A problem of sound scattering on the noise barrier with a deflector has been solved by the method of partial domains. An algorithm for calculation of the sound field in the illuminated, transitive and shadow zones has been developed. The comparative analysis of noise-suppression efficiencies has shown the advantage of the barrier with a deflector over the classical barrier. The recommendations for practical use of the considered types of barriers have been formulated. |
