Popis:	This paper is case study of noise emission of one of the most crowded highways in Tehran city. At first, equivalent noise level model of this area will be presented. Then required data for this model which were gathered, and its final output will be shown. It is concluded that in rush hours, when vehicles are in low speed and street is congested, equivalent noise emission increase dramatically. Average noise level of this highway is calculated with velocity of vehicles and the distances 24 ft from the center line of the highway. Finally, presented model will be analyzed and compared to observed values.
