TRANSPORTATION NOISE, A NEW THREAT TO MEGA CITIES AND METROPOLITAN CITIES – A CASE STUDY OF AHMEDABAD CITY
Transportation Noise, Cardiovascular dieses, Hypertension, Fetuses
In Ahmedabad city, along with development of city, transportation facility has also been improved. Improvement of transportation has many benefits though it creates many environmental problems like air pollution, noise pollution, water pollution etc. Transportation Induced Noise pollution is a new threat to Mega cities and Metropolitan cities like Ahmedabad. Noise pollution makes many adverse effect on human being like it interferes spoken communication, it causes Ear Impairment, it causes reduced task performance, it causes disruption to sleep, it causes hypertension as well as cardiovascular problems, It causes negative social behavior ect. Noise also makes adverse effect on Fetuses, newborn baby and to school going children. Due to noise, Impaired educational task performance takes place in school going children and hence Noise can be awarded as slow killer. By keeping in view to adverse effect of noise, it is necessary to know that whether noise is above or below than it is permissible limit. If noise is found above it’s permissible limit, sufficient remedial measures should be taken to save human being from it’s adverse effect. For assessment of noise in Ahmedabad city, three areas were selected. To assess road traffic noise, Gitamandir four cross roads was selected which is in vicinity of state transport bus station and hence considered as one of the most noisy areas of the city. Noise Level reading were taken separately for day time as well as for night time at every five minutes of interval. For each location, Leq (Equivalent Noise Level) was calculated separately for day time noise as well as for night time noise. The calculated Leq was Compared with Standards Given by Central pollution control board. Also it was calculated that the obtained noise level was high by what percentage with compare to standards given. The result revealed that for day time noise Leq is 76.18 dB against it’s permissible limit of 65dB (As per Standards of noise given by Central Pollution Control Board).Which was higher by 17.20 % to it’s permissible limit. By the same way Leq for night time noise was 75.68 dB against it’s permissible limit of 55 dB . Which was higher by 37.6 % to it’s permissible limit. For assessment of rail traffic noise, Maninagar Railway Crossing area was selected which is a broad gauge Railway line. It carries Ahmedabad-Bombay route which is one of the most busiest rail routes of India. The Noise Level reading were taken for day time as well as for night time. The result revealed that for day time noise, Leq was 87.28 dB against it’s permissible limit of 55 dB. Which was higher by 58.69 % to it’s permissible limit. By the same way for night time noise, Leq was 83.41dB against it’s permissible limit of 45 dB. Which was higher by 85.35 % to it’s permissible limit. For assessment of air traffic noise, residential area besides Ahmedabad airport’s runway , at Sardarnagar area was selected. This is the location which is in vicinity of runway from where mostly take off operation of aircraft is carried out. The Noise Level reading were taken during day time as well as during night time. The result revealed that for day time noise, Leq was 73.89 dB against it’s permissible limit of 55 dB. Which was higher by 34.34 % to it’s permissible limit. By the same way for night time noise Leq was 77.10 dB against it’s permissible limit of 45 dB. Which was higher by 71.33 % to it’s permissible limit.
