Traffic noise pollution level at selected cities in Kelantan

Abstract

In densely populated areas where the communities strive, noise pollution has become a critically alarming problem and must be addressed accordingly. The World Health Organization also recognizes it as a concerning public health issue in the urban areas. More often, the effects of noise towards the residents living in the vicinity areas can include the worsening of life quality and result in physiological effects, among others. We hypothesize that the increasing traffic results in higher noise pollution levels. The aim of this study was to quantify traffic noise pollution using noise pollution level (NPL) and traffic noise index (TNI) at selected cities in Kelantan, namely Tanah Merah and Pasir Mas. A sound level meter (TENMARS TM102) was used to record the noise level, and the traffic volumes were determined by using tally counts. The noises were measured during four different peak hours from 08:00 to 22:00. The recorded noise levels were compared with the Department of Environment (DOE) recommended limit of 60 dB(A) during daytime. The traffic noise pollution level was confirmed to be higher when the traffic volume counts increased. The results suggest proper mitigation measures such as enforcing zoning regulations and promoting public awareness campaigns were needed to reduce the noise pollution level.
