ENVIRONMENTAL NOISE
by Antonio C. Antonio

One of the less regarded forms of pollution is noise
pollution. Noise pollution, by
definition, is the disturbing or excessive levels of noise that may harm the
activity or balance of human or animal life.
Medical research has proven that high levels of noise may contribute to
cardiovascular problems, rise in blood pressure and coronary artery disease
among humans.
Sound is measured in decibels (db) at logarithmic scale
(meaning: a 10-fold increase in sound pressure for every 10 decibel increase). Noise pollution often results to partial or
permanent hearing. Inefficiency to some
type of human activities especially in offices and other work areas are common
results of noise pollution. In some
cases, noise pollution or the sustained exposure to noise also leads to
accidents.
Industrial activities and technological products are largely
contributory to noise pollution in contemporary history. And because of advances in technology, man
had the capacity to produce more intense and frequent sounds. The absence of melody and an intensely high
pitch makes these sounds fall in the noise category. The common source of noise is mainly caused
by machines, equipment and transport systems, motor vehicles, airplanes and
aircraft, and trains.
The term “environmental noise” is commonly used to describe
outside noise. Indoor noise is caused by
building machinery and equipment in workplaces; and enclosures where musical
sounds are excessively increased such as disco pubs, karaoke dens, concert halls
and street performances.
Poor urban planning is largely to be blamed for noise
pollution. Industrial structures and
buildings built beside and ear-shot proximity of residential areas commonly account
for noise pollution cases or cases of environmental noise.
Just my little thoughts…
