Environmental noise impact assessment from mass rapid transit to the adjacent community

Abstract

Due to the extension of the Mass Rapid Transit (MRT) network throughout the years, the noise generated from MRT had increased and this environmental noise tends to cause annoyance to the adjacent community. The aim of this research is to measure the environmental noise level generated by MRT at one of the MRT stations in Kuala Lumpur, Malaysia, compare the permissible limit and community annoyance response to the measured noise impact to the surrounding community. A total of 4 monitoring points were selected for environmental noise impact assessment. After that, a sound level meter was set up at these monitoring points to measure the sound level. For each monitoring point, the noise level was measured for 6 hours continuously from 7:00 am to 1:00 pm. Based on the results, the noise levels at critical monitoring points exceeded 9.23 % in Taman Midah MRT Station. Little community annoyance is caused in the study areas and this will affect the quality of life of the adjacent community. In conclusion, the environmental noise impact assessment was carried out to safeguard the noise level to be within the noise limit and to enhance the quality of life of the community alongside MRT.
