dc.description.abstractThe study shows that the rise and decay of train noise is best modelled by assuming the train noise to be a line source with dipole directivity. It is consistent with previous studies on train noise propagation. In planning new highrise buildings, the blocks are usually built parallel to the elevated viaduct of the rapid transit system. It is the normally held view that parallel blocks built perpendicular to the viaduct will have adverse train noise effect. Parallel blocks inclined to the elevated viaduct of the transit system do have the adverse effect of multiple reflections. However, the increase due to multiple reflections is more than offset by the shielding and diffraction effect from the blocks on the train noise. Inclining the parallel blocks could result in a reduction of 5 dB(A) of the peak train noise. The study shows that inclining the blocks will have a beneficial effect on the train noise profile. © 1997 Elsevier Science Ltd.
