Calculation of noise characteristics flow of railways

The article presents the theoretical curves are equivalent and maximum noise levels generated by individual trains on the rate obtained by linear regression calculations. It also provides analytical expressions for calculating the hourly equivalent sound levels generated by trains of rail transport flows of all types that have passed on their way to the site under consideration for one hour and at regulated intervals, day and night time. Shows the relative noise spectra of rail transport, allowing to determine the calculated spectrum of the noise characteristics of the trains.
