Abstract
The problem of sound radiation from two trains is considered. This object has been simulated as sets of point sources uniformly distributed in domain of two lengthened rectangles moving in opposite directions. The solution of problem is obtained using integral Fourier-transforms over space coordinates and time. The integrals are calculated using the stationary phase method. Numerical analysis is performed for acoustic pressure and sound intensity.
