Noise and its effect on human being--a review.

Noise pollution, as it affects human being, has been a recognised problem for decades in the developed countries, but it is still ignored in the developing and underdeveloped countries. Effects of noise on human beings often presents conflicting results because of the variety of factors and variables that can effect and/or interfere with the determination of the actual effects. This is because the response of the people vary place-to-place, situation-to-situation for the same noise level. This subjective response has been quantified by various researchers and indicated with different indices. This paper highlights the research carried out by different scientists across the world on the harmful effects of noise on human being.
