Abstract

In this study, the insertion losses of various track-side railway noise barriers are analyzed by using a two-dimensional numerical boundary element method(BEM). The BEM is implemented using two out-of-phase monopole sources for each track to represent dipole source. All model for this study is based on actual size built in Test Line of KTX. And the results suggest that vertical absorptive barrier provide as effective screening as rigid barrier which is more 0.4 m than the height of those.
