The main objective of this study is to analyze and evaluate road traffic noise in the City of Al-Dammam. Digital sound level meters with frequency weighting networks were used in this study. All measurements were taken on an A weighting frequency network, at a height of about 1.5 m from ground and on a fast range time weighting. The A weighting characteristics and Fast range simulated the human ear listening response. Noise measurements were taken at locations in selected districts. Day-night and day time noise maps were then drawn with the districts being classified into moderate, high and extremely-high risk zones in accordance with noise risk levels. Mean day-night (Ldn) values obtained ranged from 68.1 to 90.6 dB (A) and exceeded the permissible environmental standards used in Kindom of Saudi Arabia while mean day time (Ld) values ranged from 75.3 and 85.4 dB (A). They too exceeded permissible limits. This indicates that residents of all locations investigated are exposed to high noise levels mainly caused by road traffic. |
