EU-S2R-OC-CCA-01-2019: Noise & Vibration

The proposed research shall address the workstreams described below: Exterior noise: Work stream 1: Exterior noise simulation tools. Proposals should provide modelling of exterior noise adding together noise sources placed on different parts of the train to simulate the resulting noise levels. Work stream 2: Pass-by noise source separation. The objective of this work stream is to develop novel and innovative techniques to get the sound power level and directivity of the different types of noise sources during pass by at constant speed of a train. Work stream 3: Separation of track noise versus [...]
