Abstract
Nowadays, rail transport is one of the most important transport modes chosen by Malaysians. However, the noise pollution caused by the railway causes complaints from residents living near this track. Therefore, the operator needs to order their workers to conduct monthly observations and measurements of their train noise level in the selected area. The conventional method requires more time and energy as the number of areas to monitor is various and the sound level measurement tools used are also expensive. Thus, a study was carried out to determine the current noise level produced by MRT train in the residential areas near to the Pusat Bandar Damansara station. The noise level measurement was conducted at Lorong Kasah Tepi and Medan Damansara Carpark, which are located nearby the Sungai Buloh�Kajang MRT Line. The noise level was measured at each location with three different slope distances using a sound level meter during operating and non-operating hours. Other than that, MRT speed and wind speed were measured as predictors to develop the Mass Rapid Transit Noise prediction model using the stepwise regression analysis. From the analysis, 88.37% of variation in Mass Rapid Transit Noise can be explained by the regression model. � 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
