ABSTRACT Environment pollution is a major problem of the world and it is mainly influence to the health of human, animals and ecosystem. The World Health Organization (WHO) has documented seven categories of adverse health and social effects of noise pollution, whether occupational, social or environmental: hearing impairment, interference with spoken communication, cardiovascular disturbances, mental health problems, impaired cognition, negative social behaviors and sleep disturbances . The physical manifestation of noise pollution is the effect on hearing ability. Hopefully, with more upcoming research, there will be more emphasis placed on reducing noise pollution in the community. To maintain a healthy body and a healthy mind, one needs a minimum specific period of proper sleep. The physiological manifestations are headaches, irritability and nervousness, feeling of fatigue and decreases work efficiency. Physiological effects of noise pollution. Such an effect is already observed in Alipore Zoo in Calcutta. Hearing loss and rapid increase in heart rate are some of the ill-effects of noise pollution on animals. The physical manifestation of noise pollution is the effect on hearing ability. High intensity sound induces fear, forcing them to abandon their habitat. The hearing loss starts in the frequency range of about 4000 Hz. This effect is more severe on old people and children. – Joel Reynolds, NRDC senior attorney (http://www.nrdc.org/wildlife/marine/sonar.asp), This is not only about whales, but the larger marine life are all affected in one way or the other.

Research has shown that industrial workers regularly exposed to high noise levels have higher cases of nausea, headaches, argumentativeness, and changes in mood and anxiety. Wildlife (animals) faced more problems than humans due to noise pollution because they are more dependent on sound. (SONAR is the use of sound by submarines and other fishing vessels to deterring the depth of water, the closeness of an object, or detect movement of other objects in the water). Noise may contribute to distress and emotional disturbance. Noise pollution is pervasive across every ecosystem on Earth. Noise interfering with sound system might mask the warning signals, thereby increasing the incidence of errors making accidents more likely. However, with increasing noise pollution, the body is under chronic stress, releasing adrenalin (epinephrine) and noradrenalin (norepinephrine). Its is worth noting that these effects may not sound troubling, but the truth is, with time, the consequences can be very worrying. Repeated exposure to noise may result in temporary or permanent shifting of the hearing threshold of a person depending upon the level and duration of exposure.

Loud and sudden noises in your immediate environment are likely to be rare, but the distant noise of traffic,construction, people surrounding you, and various kinds of dinging and ringing all contribute to an environment polluted by noise. For example, being pounded by the siren of fire fighters, police or ambulance in your city all night everyday leave people (especially elderly people) stresses and tired in the morning. Noise can affect sleep by causing restlessness and lowered REM. Adding to sound pressure adds to workplace stress, which escalates the problem of workplace noise. It raises heart rate, increases blood pressure, enhances perspiration and breathing rates, causes a tendency to vomit, dizziness and fatigue. These particular catecholamines, including dopamine, cause the release of cholesterol from lipoproteins, thus adding to the cholesterol tide when so many already have high cholesterol.
