Sound is part of our everyday lives, and it is how all of us communicate to one another. Some of the sources and activities that include sound are speech, music, animals, and many more. But there are occasions in which sound causes annoyance and stress to the people around, and we refer to this as noise.
A sound may be considered noise pollution if it disturbs any natural process or causes human harm, even if the sound does not occur on a regular basis.
In places like pubs and clubs, very loud music can actually damage our ears and disturb the surrounding neighbourhood during the wee hours of the night.
- Normal Conversations Sound Intensity : 40-60 db
- Entertainment noise Sound Intensity : 80 db
The main source of noise pollution comes from transportation such as airplanes, cars, and buses, as well as recreational vehicles such as jet skis. With sound intensities ranging from 90db – 200db, these vehicles cause annoyance, stress, and even hearing loss in humans.
Other sources include noises from constructions, industrial noises from factories and even noises from home equipment such as the vacuum machine and kitchen appliances.
