Railway applications. Noise emission. Characterization of the dynamic properties of track selections for pass by noise measurements Ingestion-build-135476 you can demonstrate the reliability1 Scope This European Standard specifies a method for characterizing the dynamic behaviour of the structure of a track relative to its contribution to the sound radiation associated with the rolling noise. This European Standard describes a method for: a) acquiring data on mechanical frequency response functions on a track; b) processing measurement data in order to calculate an estimate of the vibration decay rates along the rails in an audible
