EXPERIMENTAL RESEARCH ON PREDICTION STRUCTURE-BORNE SOUND DUE TO THE ENVIRONMENTAL GROUND VIBRATION

Structure-borne Sound – Phenomena and Prediction

The prediction of the sound radiated by vibrating structures and the layout of measures to reduce it, is a key issue for maintaining appropriate comfort in residential buildings, for guaranteeing the operability of sensitive machinery in production and testing and for the provision of appropriate conditions at working places. For the prediction the excitation, the transmission and the radiation...

Influences of Railway Track Geometry Parameters on Ground-Borne Vibration

One of the most important challenges in the development of urban railways network is the effects of railway vibrations on human and adjacent structures. Although various investigations into the sources of railway vibrations have been conducted, very few research works have been reported on the influences of track geometry parameters on the level of vibrations. This is addressed in this resea...

Numerical modelling of ground-borne noise and vibration in buildings due to surface rail traffic

This paper deals with the numerical computation of the structural and acoustic response of a building to an incoming wave field generated by high-speed surface railway traffic. The source model consists of a moving vehicle on a longitudinally invariant track, coupled to a layered ground modelled with a boundary element formulation. The receiver model is based on a substructuring formulation and...
