Abstract
The emission of sound in the environment, or in other words, the control of noise pollution, has become one of the major problems of densely populated cities. The importance of the problem of noise pollution is revealed when it endangers the health and mental health of residents of residential areas. Hearing loss, nervous and mental disorders, fatigue and boredom, lack of sleep and the complications resulting from it are all subtle complications of noise pollution that must be taken seriously. As the population in metropolitan areas increases and they move closer to the busy highways, noise pollution in those areas has increased dramatically. For this reason, standards for noise pollution in different urban areas have been established, which are a measure of pollution. Various models have been proposed for calculating the amount of noise pollution, each of which has a correct computational value. Using the model used, the noise level on the highway is calculated according to the traffic and geometric parameters of the road and compared with the permissible noise standard in Iran.
