Mathematical Modeling of Environmental Noise Impact

Noise can have negative impact on health. Hearing damage, annoyance, sleep disturbance, high blood pressure, poor cardiovascular health is all linked to community noise. Children, people with existing physical and mental illness and elderly people are most susceptible to community noise. High level of noise from sources such as busy traffic can adversely affect the health of the people living near road highways. It is therefore desirable to model a road traffic noise that predicts well the traffic noise near highways so that the people living near highways who are highly exposed by everyday traffic noise can be protected from noise exposure to some extent . Measurement of noise level ( ) (A dB ) by noise analyzer will be conducted on road segment of Dehradun Haridwar highway for Dehradun city at different locations. The noise level predicted from the developed model is compared with the measured one .t-test is then applied and observed highly significant at 5% level and 95% confidence level. The proposed road traffic noise model can be effectively used as a decision supporting tool for prediction of road traffic noise in Indian conditions. Examining the behavior of various factors affecting road traffic noise, people living near highways can be better prevented from high degree of environmental noise impact.
