Noise emissions play a key role in the development of environment-friendly rolling stock. Noise limits given by EU directives for interoperability purposes but also by internal directives of the different countries where any kind of rolling stock ope

Noise simulations are performed by train manufacturers during the development of new rolling stock. They are used to evaluate compliance with the customer’s expectations and requirements demanded by train operators based on existing regulations. Th

The first objective of the acoustical design of rolling stock vehicles is the compromise between passenger comfort and the technical and economical means required to achieve it. Typically, global A-weighted sound pressure levels are used to evaluate

The radiation mechanism for rolling noise is shared between the vehicle wheels and the track (rails and sleepers), both excited by the combined roughness of wheels and rail. Depending on the track characteristics and vehicle speed, track noise can of

This paper presents a prediction of the acoustic wall pressure levels on a rolling stock vehicle from wheel-track interaction. This study has taken into account two different approaches: beam-tracing and boundary element calculations. The two types o
