Noise is defined as unwanted sound. Those who mostly live in crowded cities and towns are only too familiar with noise. This is so much so that neighbourhood associations always petition the relevant authorities to limit noise in residential areas. This is all for good reasons as noise has been dubbed as not just an annoyance, but also an unknown and silent killer.

First, where does all the noise come from? Nearly every economic activity generates some noise. What matters is the extent, measured in what is known as decibels, or simply the intensity of the noise. In urban centres, traffic is a major source of noise. Think of all the cars, buses, trucks and motorcycles on unending trips. Then there are industries, entertainment joints with loud music, and even unruly neighbours with overnight parties and constantly barking dogs. Countless daily activities are endlessly churning out intolerable noise.
