A simplified method of evaluating air absorption, in terms of A-weighted sound pressure level and A-weighted sound exposure level, is worked out. The results obtained can be used for prediction of equivalent continuous A-weighted sound pressure level of traffic noise. Up to a few hundred meters from

Railways are becoming increasingly market-driven. Consequently, it is important that passengers are provided with a comfortable environment that re#ects the operator's desired image for the service. A major factor in determining how passengers perceive the environment within trains is the level and
Finite element and boundary element calculations are combined to predict the flow noise radiated from a 1/10thscale model of an aerodynamic cover used around the pantograph on a train at 250 km h ΓΏ1 . The solutions of the unsteady air flow over the cover and the resulting sound propagation are divid
