Analysis on noise distribution at different monorail station in Kuala Lumpur

Alias, Ahmad Arif (2015) Analysis on noise distribution at different monorail station in Kuala Lumpur. Masters thesis, Universiti Tun Hussein Onn Malaysia.



Railway services in Malaysia has grown rapidly over the past decades. At present the noise level problems in the stations area created uncomfortable condition to consumers. This dissertation focusses on the monitoring of noise level in selected monorail station areas in Kuala Lumpur. The objective of the project was to monitor the noise levels at the selected station. The two selected station were Maharajalela Station, and Titiwangsa Station. Sound Level Meter (SLM) was used in the measurements. For each station, data was collected during day (09:00 am – 04:30 pm) and evening (08:30 pm – 11:00 pm) for three days. The measurements were taken at an interval of one second at appropriate points in accordance with Department of Environment Malaysia Standard. It should be noted that monitored noise levels were in terms of (Leq), maximum noise level (Lmax), and Minimum noise level (Lmin) around the platform area. Noise levels at Titiwangsa Station were higher than Maharajalela Station. Result shows, at Maharajalela station, the noise level ranged between 71 dB(A) to 75 dB(A). Besides that, at Titiwangsa station, noise levels ranged between 73 dB(A) to 76 dB(A). The SPL’s generated have exceeded the recommended level, which is 70 dB(A) by the Department of Environment (DOE). For each point at MHJS and TTS during daytime, the maximum noise levels happened by seconds only. Even though it happened for a while, it does effects users, especially children and elderly people. It was found that, one of the main factors that contribute to this station noise is noise released by the movement of traffic under the station. As a result of this research, some suggestions on how to control the noise generated in the monorail station are drawn. Appropriate materials that can absorb noise generated at the station should be installed, especially at the waiting area/platform. Other than that, always ensure that the brake system of the monorail is maintained properly.
