Environmental Noise Pollution At Selected Primary Schools With Different Population Density In Malaysia

Abstract
Majority of primary schools in Malaysia are located near the roadside, thus facing problems of noise pollution. Children exposed to high noise level significantly diminished their concentration in class, social flexibility and intensify inverse relationship with other people. The increasing number of motor vehicles is among the triggering factors that contribute to the noise pollution. This study investigate the level of traffic induced noise pollution at three primary schools in Kuala Terengganu with different population density of low, medium and high. Noise levels comprising of Lmax, LAeq, Lmin, L10 and L90 were measured over six days at each schools, i.e. three school days and three non-school days from 0700 hours to 2200 hours each day. Results showed that noise level at each location is significantly different (P<0.05), and at all sites, the noise level exceeded the permissible limit. Principal Component Analysis (PCA) showed that the classes of motor vehicles that significantly contribute to noise level are from Class L, M, N and O. Highest noise level was recorded at school located within the high density area, followed by medium density and low density area respectively.
