Abstract
The influence of ground effect on railroad noise is described using the concept of the peak A-weighted sound exposure level, and A-weighted sound exposure level. The train is modelled by the continuous line of incoherent point sources which have the cosine directivity. The ground effect is included by the Weyl van der Pol solution with the single parameter model of the ground impedance. The method of determining of the referenced A-weighted power spectrum is presented.
