Assessment of Traffic Noise Pollution in Bukit Mertajam, Malaysia and Erbil City, Iraq
Journal Title: Caspian Journal of Applied Sciences Research - Year 2012, Vol 1, Issue 3
Abstract
Road traffic noise has become an important factor in societal development. Traffic noise from motor vehicles can inflict serious damage to human health and reduce labor productivity. Traffic noise measurements were taken at two locations: Bukit Mertajam, a developing town in Malaysia, and Erbil City, the regional capital of Iraqi Kurdistan. Field measurements were taken simultaneously with traffic volume measurements in Bukit Mertajam, and then validated using various models. The NAISS model represented the field measurements better than did the other models used. The noise level was higher during peak hours, particularly during evenings when there were increased traffic volumes and a higher percentage of heavy vehicles. The average noise level exceeded the guidelines set by the Malaysian government. The sound pressure levels (SPLs) for Erbil City were higher during mornings, and decreased as distance increased. The correlation coefficient obtained for SPL and the distance between the sound source and receiver indicates a good relationship.
