Comparison of pass-by railway noise indicators obtained from standard engineering methods with measured values

Abstract : Long-term averaged indicators are commonly used to dimension protections and satisfy existing regulations for railway infrastructures. These long-term indicator are generally used to assess the exposure of populations to environmental noise and, in turn, to evaluate health related effects. However, long-term indicators may not correlate well with noise perception by residents. In case of high speed train pass-by, for example, short-term indicators are more directly linked to the maximum noise levels and the duration of the event. For rolling stock characterization, indicators such as LA eq,Tpb>, SEL, TEL and LAmaxare commonly used. As an extension, such indicators, including LAeq,Te may also be used to assess the noise perceived by residents for single pass-by events. A new calculation scheme, compatible with existing normative methods, has been developed for predicting event-related noise indicators in complex environments, under varying meteorological conditions. The prediction methods are adapted to obtain the time-dependent sound pressure level time during the train pass-by and then to derive the different short-term indicators. This paper presents a validation study comparing measured and calculated short term indicators according to current engineering methods. Results are given for different trains and speeds as well as different sites and receiver configurations.
