Railway rolling noise synthesis using a numerical modelling approach
Railway rolling noise synthesis using a numerical modelling approach
Rolling noise is the major source of noise in railways at conventional train speeds. It is radiated by vibration of the wheel and track excited by the combined wheel and rail surface roughness [1]. Rolling noise prediction models such as TWINS (Track-Wheel Interaction Noise Software) [2] are principally designed to predict sound power accurately in the frequency domain, combining numerical and analytical methods. In the EU project Acoutrain [3], a sound propagation model was developed for modelling the temporal evolution of the sound pressure level during train pass-by. The wheel and track were simplified to moving point sources based on the sound power predicted from TWINS and simplified directivities. Models for the auralization of railway noise were implemented by Pieren et al. [4, 5] or Theyssen [6]. In this paper, a new numerical model based on the TWINS approach is employed for the synthesis of pass-by rolling noise signals using state-of-the-art wheel and track models that allow accurate calculations up to high frequencies.

Abstract
Rolling noise is the major source of noise in railways at conventional train speeds. It is radiated by vibration of the wheel and track excited by the combined wheel and rail surface roughness [1]. Rolling noise prediction models such as TWINS (Track-Wheel Interaction Noise Software) [2] are principally designed to predict sound power accurately in the frequency domain, combining numerical and analytical methods. In the EU project Acoutrain [3], a sound propagation model was developed for modelling the temporal evolution of the sound pressure level during train pass-by. The wheel and track were simplified to moving point sources based on the sound power predicted from TWINS and simplified directivities. Models for the auralization of railway noise were implemented by Pieren et al. [4, 5] or Theyssen [6]. In this paper, a new numerical model based on the TWINS approach is employed for the synthesis of pass-by rolling noise signals using state-of-the-art wheel and track models that allow accurate calculations up to high frequencies.
