Prestasi Akustik Stesen Mrt (Mass Rapid Transit) Bawah Tanah Berdasarkan Penggunaan Bahan Binaan

Abstract

The existence of public transport services system such as MRT (Mass Rapid Transit) is one of the most important aspects in an urban environment. Nevertheless, the impact of sound produced by the trains and the crowds are causing disturbance to the urban environment. The importance of this study is to identify the impact of building materials in the acoustic performance of the underground MRT station in improving the level of users’ comfort. There are three methods of data collection in this study. The first method involves data collection from articles, thesis and books related to the acoustic performance and human comfort. The second method is based on the data collection on site which involves the measurement of the acoustic performance inside the existing MRT underground station using decibel meter. The third method involves the study of the acoustic performance inside the underground station by producing 3D models and by running acoustic simulations within the station models through I-Simpa software. MRT Cochrane station in Cheras was selected for the studies based on its characteristic which is located at the underground level and largely enclosed. Based on the collected data from the field measurement and the computer simulation, this study manages to determine the acoustic performance of the MRT underground station and further proposes acoustic improvement through the manipulation of building materials.
