    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 a continuous line of incoherent point sources that have a 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.
