RAILWAY NOISE PREDICTION MODELS: A COMPARISON

This paper represents a comparison between some European prediction models for rail traffic noise. These models are from Austria, Denmark, France, Germany, The Netherlands, Norway, Sweden, Switzerland and the U.K. In the propagation part the ISO 9613-2 is also considered. The comparison of the noise emission gives results for disc- and block-braked passenger trains and for freight trains. For purposes of comparison the propagation model is divided according to the usual attenuation elements including geometrical spreading, atmospheric attenuation, ground attenuation, screening attenuation and reflections. These attenuation effects are compared separately.
