In this paper ,the study on the prediction model for railway
noise,prediction on the maximum sound pressure level for
railway system in Taiwan area and its corresponding using to
calculate the relating equivalent sound pressure level are
included.Discussing the above prediction model ,two assumptions
that the condition of railway is good enough and the major
source of railway noise is coming from the effect of
interaction between rail and wheel of vehicle are considered
.Therefore,the above assumptions is used to derive the involved
theory and a semi-empirical model is also obtained by
regressing the actually measured results. Because of different
type of vehicle for railway system in Taiwan area,four
prediction models for four different types of vehicle, which
are tzyh-chyang express, jeu-guang express, fuh- shing express
and general trains,are considered.In the other hand,based on
the influence of ground,the models for far and near rails as
viewed from the measured position should be separated. So that
eight different prediction models totally considered in this
paper. Finally , the comparison of the all actually measured
result with those of prediction shows that an excellent and
accurate prediction model has been provided by this paper.
