Abstract
The purpose of this study is to determine the noise exposure level among the workers that working in construction area. The study was carried out at construction sites and workshop. The data of noise level was collected by using Noise Dosimeter (SIE95) and analysed by dBTRAIT software. Result shows the maximum of noise dose (D) for Sri Gading and UTHM is approximately 43% and 28% respectively, while time weighted average noise level (TWA) for these sites is about 84 dB (A) and 80.8 dB (A) respectively. IKBN recorded maximum of noise dose (D) and average noise level (TWA) is 88 dB (A) and 75.8% respectively. The level of noise exposure at selected areas is in acceptable range based on regulation. As conclusion, workers who at the areas are advisable to wear hearing protection device when construction activities take place in order to civilize safety practice in the industry field.
