Changes in the acoustical environment arising from new railway extension: A case study of Hong Kong
Refereed conference paper presented and published in conference proceedings



摘要The operation of a new railway changes the acoustical environment not only through the introduction of a new noise source but also through consequential changes in the traffic mode and pattern. This study investigates such changes in a community following the opening of the Ma On Shan Rail in Hong Kong. The findings show that there are changes in the use of private and public transport as well as in the routes and frequencies of bus and mini-bus operations. These traffic changes have resulted in changes in the acoustical environment in the community. At the same time, the new rail system has created some noise impacts on residential units located adjacent to the railway. These acoustical changes have been determined by noise mapping with which the spatial pattern of acoustical changes, both in terms of noise intensity and source, can be ascertained. The information so obtained can also be used to assess possible human annoyance reactions based on increase or decrease in the noise level and changes in the source of traffic noise. Some preliminary findings of a human response survey of the new railway are presented in this paper.
