A Study of Noise Pollution in Greater Noida City – U.P., India

Abstract — Sound in the environment is caused by the quivering of particles present in the air that reaches the human ears and stimulates a feeling of hearing. When sound becomes loud, or disagreeable, or unwanted, or annoying, it becomes noise. This production of noise causes some undesirable effects on the human being as well as on animals, therefore this noise is also termed as environmental pollutant such as air pollution, water pollution etc. Noise can cause annoyance, diseases, sleeplessness, communication interference, hearing loss etc. due to which it should be controlled in the surroundings. The Air Act 1981 also includes noise as one of the air pollutant. In this paper, the noise pollution level and its impacts on the environment of Greater Noida a small city of Uttar Pradesh, India is discussed. In this area the major sources of noise pollution are vehicle horns, commercial areas and industrial areas. The sound pressure level is measured at morning, noon and evening during the peak hours. It is found that in the most areas of the city the prevailing noise level is more than the ambient noise level. In Greater Noida the average prevailing noise level through the vehicle is 83dB which is far more than the desired level of noise. The city is developing rapidly due to which the number of vehicle are increasing day by day and hence traffic noise is also increasing that has to be analyzed and controlled for the sake of human health. At the end of the paper some fruitful suggestion for noise abatement and control has been discussed
