This paper presents methods for modelling and assessing the acoustic environment inside and outside rail vehicles, and in railway infrastructure such as stations. The main focus is on computer modelling using geometrical acoustics (ray-tracing) with further remarks on the use of statistical energy analysis for vehicle structures, finite element and boundary element acoustic models and some similar special methods for local models of components and construction details such as floor and trim panels. Various examples show how the methods can be used in practice. In the aural presentation, some synthesized (predicted) acoustic samples are replayed.
