چکیده
The equivalent noise level in large cities has been growing due to the population growth, uncontrolled production of cars, and the existence of worn out cars. On the other hand, heavy traffic has increased the amount of noise problems for residents of medical and educational centers, research institutes and residential area (or sensitive centers to noise) built in highway bounds and it has also caused and added to their stress and discomfort. This paper presents the results of measurement of equivalent noise level (Leq) on various roads in Tehran. The noise maps and color contours resulted from modeling of the noise emission sources, and the critical zones in these area have been identified through the noise pollution aspect and have been studied and the appropriate solutions have been suggested. It is possible to decrease the level of noise pollution in those zones effectively, through modeling and identifying the critical zones and also by presenting noise control solution.
