Noice Level Monitoring Programme

 

NOISE LEVEL MONITORING

Air (Prevention and Control of Pollution) Act, 1981, (Amended) in 1988 considered noise as air pollutant. After this M. P. Pollution Control Board has taken up this task and has been monitoring noise levels in major cities of the State through regional offices. This will help to assess the Noise Level Status and its causes. This will further help in planning, control and mitigation of the ill effects caused due to this problem.

Main sources of noise are industrial complexes, motor cars, loud speakers, trains, supersonic booms from airplanes etc.

High noise levels have deleterious effects on human beings as well as animals. A constant exposure to noise over a long period may cause loss of hearing. Excessive noise causes physical strain, mental fatigue, headache, nausea and sleep disturbances. Sudden and unexpected noise may cause increased blood pressure, increased heart beat, muscular contraction, damage to heart and imbalance in chemical composition of the body. 

On the basis of locality, the ambient noise standards have been framed; day time limits for industrial, commercial, residential and silence areas are prescribed as 75, 65, 55 and 50 dB. respectively. The night time limits for the same zones are 70, 55, 45, and 40 db. respectively.

The findings of  Noise levels for the year 2006-2007 is shown in  tabulated form.
