Noise pollution is unwanted or excessive sound that can have deleterious effects to human health and environmental quality. In recent times noise pollution has been increasing rapidly causing serious threat to environmental quality. . Increase in noise pollution has also been causing negative impacts on the human health. Exposure to higher noise levels may lead to aggression, hearing loss, stress, sleep disturbance and so much more psychological issues.

One of the main sources of noise pollution is transportation, especially noise generated by road traffic. Other major sources such as factory machinery, construction equipment, power tools, DG Sets and loudspeakers can also cause noise pollution. Among all these motor vehicles are the dominant sources of noise pollution.

The problem of Noise pollution has gained significant attention from the environmental point. The Ministry of Environment and Forests (MoEF) has recognized the problem and notified noise related regulation like Environment (Protection) second Amendment Rules, 2002 and Noise Pollution (Regulation and Control) Rules, 2010. These regulatory requirements emphasize on the application of noise control measures. The forecasting the impacts of noise from various sources using environmental noise modeling will certainly provide valuable input in decision-making. The noise models describe the process of theoretically estimating noise levels within a region of interest under a specific set of conditions. Noise Model can be used to identify the receptors exposed to excessive noise and enables the implementation of mitigation measures which also could include sound barriers.
