| dc.description.abstract | This study intended on the assessment of road traffic noise in Sekolah Kebangsaan Sungai Bakap where this study area located near the main road Jalan Sungai Bakap (Route 1). The objectives of this study were to determine noise levels during school hours (8.30 a.m to 12.00 p.m), to identify the source of noise using sound level meter (SLM) and to establish noise mapping in the Sekolah Kebangsaan Sungai Bakap environment. With using sound level meter (SLM) instrument, the noise levels at school were measured where 19 points were randomly selected at school area in order to collect the value of all parameters measured in this study (Leq, Lmax, Lmin, L10, L50, and L90). Each of the noise measurements was taken for three (3) minutes in duration and the time is taken for all measurements conducted from 8.30 a.m to 12.00 p.m. Noise mapping performed using ArcMap and My maps website based on the latitude, longitude and also noise parameters. Manual traffic count was conducted to count the number of vehicles on the road. Traffic composition data in this study is categorized into four types, which are passenger car and van, motorcycle, medium lorries and heavy lorries according to the Arahan Teknik Jalan (8/86), A Guide on Geometric Design of Roads, 1986 under Jabatan Kerja Raya (JKR) where the findings show that increasing numbers of vehicles are increasingly high in noise. The result showed that the measured noise levels at school area in term of Leq between the ranged of 54.8 dB(A) to 72.9 dB(A) respectively where it was found that most of the data collected had highest value of noise level located in road zones. From this study, all noise data collected are exceeded by the planning guidelines for environmental noise limits and control under the Malaysian Department of Environment. Apart from that, based on the noise map, it showed that highest noise levels were located in traffic zones areas. | en_US |
