Monitoring of environmental noise - noise source modeling for polish passenger trains

The study performed is a part of the project devoted to monitoring of environmental noise. The result of the IMAGINE noise source prediction model implementation based on reference data of that model is presented in this paper together with the main objectives of the realized study. The model implementation outcome is compared with the real-life measurement results and discrepancies between prediction and measurement results are determined. Problems of reference data that are not fully applicable to Polish railway structure are described in details. Moreover, the problem of a proper assignment of the distance between the noise meter location and the track centerline is also discussed. A possibility to apply this method to dynamic noise mapping is covered as well.
