In view of the rapid high-speed railway transport development in the world, the question of ecological safety of the people living in the areas adjacent to transport infrastructure networks, including physical factors compliance, becomes crucial. The article introduces problems of high-speed railway noise control and prediction (with train speed from 250 to 400 km\h), calculation methods for determining high-speed train noise characteristics; comparison of the calculation and experimental results is made. The article describes main ways of high-speed train noise reduction, in the noise source in particular, such as installing small local noise barriers and aerodynamic streamlining of the rolling stock and its separate elements (pantograph, etc.), implemented in China, Japan, France, German, South Korea and other countries. The article also considers efficiency of the main practically applied noise mitigation measures.
