According to Olusegun, Temitope and Harold
(2012) noise in the environment includes both unwanted and wanted sound that is
capable of impacting human health and wellbeing.

also defined noise pollution or noise disturbance as the disturbing or
excessive noise that may harm the activity or balance of human or animal life.
The source of most outdoor noise worldwide is mainly caused by machines and
transportation system, motor vehicles, aircraft and trains.

Noise pollution arising from factories
is unexpectedly higher than some medium to large scale factories. More
worrisome is the deleterious effects of emitted noise on exposed workers and
nearly residents who wear no protection and have poor awareness of risks
associated with noise pollution exposure.

Sound intensity is usually measured on
the logarithmic decibel (dB) scale often weight to discriminate against the
lower frequency as our own ear drum (dBA). A chain saw as the one to be
considered in this study has an A-weight average intensity of 110 dB.

Noise is considered hazard to the
health of people everywhere, which is another man’s environmental physical
hazards that many people hardly believe the effects on the health of the
individual like hypertension, noise has also been called a silent killer. This
is so because the effect of noise is very insidious.

Noise consists of a persistent and
uncontrollable sharp sound of more than 80 to 90 decibels. It may range from a
persistent bark of a dog, blasting of a neighbour’s stereo or the insistent
blare of a car burglar-alarm or radio noise to individual noise (Olojoba, 2009).

It is estimated that 6-16 millions
worker in the United States work in noisy surroundings that may impair hearing.
However, a study by the national physical laboratory indicated that “the
biggest source of noise for a person is vehicular traffic (Olojoba, 2009).

A recent survey in noise-prone industries
(oil, textiles, steels mill, automobiles industry and railway workshops)
reveal, a noise level of 92-102 decibel (Olojoba, 2009).

It may be mentioned that as
demonstrated by Theodore Wacks at Purdue University in 1982, ordinary household
noise also can retard the cognitive development of children aged 7-24 months
even the foetus may suffer from undesirable effect of noise (Unuraye, 2008). A
recent study advocated that pregnant women avoid prolonged exposure to noise
(Olojoba, 2009).
