Realization the high-speed railways noise calculation

The article contains the basic formulas for calculating of noise from high-speed trains, including the formula for calculating noise of pantograph, body, nose and noise from wheel and rail. The article shows the method for calculating the noise characteristics of high-speed train at a height of 3.5 m above the railhead. Author indicates the changes that were made to the methodology published in the earlier works. The main results of scientific work have been applied in the development of special technical conditions and a set of rules dealing with the calculation of noise from high-speed trains.
