This thesis present the theoretical study and field measurement of noise exposure in industry based on the noise exposure regulations 1989. The thesis presented herein is discussed about the high noise arising from the factory in Malaysia. Noise measurements were conducted at one of the factory in Batu Berendam, Malacca. Noise measurements can provide an evaluation of the noise exposure levels and the assessment of the risk of hearing impairment of the worker in the factory. The noise levels and noise type characteristics can be obtained from the punching room. From the room, the noise exposure of the workers was in between 91 - 95 dBA. We discovered that even though a combination of many complicated techniques and specialized knowledge of acoustics, the noise zoning can be mapped out by using AutoCAD, Acid Sonic & etc. software. From the chart, we can see the noise zoning, which allows us to identify the boundary line of different noise levels in the room. Besides that, a comparison between the theoretical & experiment measurements was made in order to analyze the results. Finally, the room prediction of noise levels was made if two more machines were added into the room. The results showed that the predicted and theoretical results yield a good agreement in terms of minimal error.
