The prospect of the new railway construction has led to resistance from residents, partly based on noise and vibration issues. Particularly, as tracks often pass closely to residential dwellings, constructors are then required to take account of noise and vibration. So the prediction of noise and vibration for train is very important thing. The train noise and vibration nearby the elevated railway make one specific issue. For the elevated railway, this paper concerns the rolling noise by the wheel/rail and the structure-borne noise by the bridge. Based on the results, this paper proposes the source model of elevated structure-borne noise and the calculation model for elevated railway noise. Also prediction model is presented with rolling noise and elevated structure noise which are calculated by considering the power level of a source for one-third octave band, ground absorption and barrier deflection. A lot of empirical data is needed to predict the noise and vibration. And one of the best ways to control the wayside noise is to analyze the noise level.
Abstract
The prospect of the new railway construction has led to resistance from residents, partly based on noise and vibration issues.

So the prediction of noise and vibration for train is very important thing. The train noise and vibration nearby the elevated railway make one specific issue. For the elevated railway, this paper concerns the rolling noise by the wheel/rail and the structure-borne noise by the bridge. Based on the results, this paper proposes the source model of elevated structure-borne noise and the calculation model for elevated railway noise. Also prediction model is presented with rolling noise and elevated structure noise which are calculated by considering the power level of a source for one-third octave band, ground absorption and barrier deflection.
