Analysis of the efficiency of low noise barrier using STERED material

When reducing noise, especially around the so-called corridor railway tracks, but also at the hump yard, the most suitable structure and composition of acoustic barrier materials are searched. It is also issue of the durability and stability parameters of the acoustic properties of the materials used for different climatic conditions. In the paper the experimental verification of the required and the expected acoustic properties of the newly-designed low acoustic barriers exposed to real noise from the hump yard are
