INTRODUCTION
Noise pollution is an act in which displeasing
human or machine created sound that disrupts the
activity of balance of human or animal life is
introduced to the environment. It can equally be
described as an unwanted or excessive sound dumped
into the environment without regard to the adverse
effects it may have.It is an undesirable by product of
our modern way of life. Industralisation and
modernisation has given rise to a new form of
pollution, noise [1]. Gradually, noise has become an
important environmental pollutant and in big cities is
considered by the World Health Organization (WHO)
to be the third most hazardous type of pollution, right
after air and water pollution [2].
