TRIUKŠMĄ MAŽINANČIŲ BARJERŲ EFEKTYVUMO PRIKLAUSOMYBĖ NUO FORMOS IR GEOMETRIJOS.

The work examines noise barriers and evaluates their effectiveness when changing their geometry and shape. Noise barriers are one of the most effective and widely used methods of reducing noise caused by road and railway transport. The effectiveness of the barrier depends on the materials used in the construction, the barrier's height, geometry, shape, and the acoustic properties of the additional elements installed on top of the barriers. The aim of the work is to review and analyze the scientific literature, which would allow to evaluate the dependence of the acoustic characteristics of noise-reducing barriers on the geometry and shape of the barrier, and to provide recommendations for the design and selection of noise barriers.
