In the narrowest sense, sounds are considered noise pollution if they adversely affect wildlife, human activity, or are capable of damaging physical structures on a regular, repeating basis. In the broadest sense of the term, 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.
The causes of noise pollution in general are obvious - construction sites, highway vehicle traffic, industrial companies, air traffic, rail traffic, fire workers and others. While many of these sources are unavoidable in daily life, the exposure to them can be kept to a minimum with a little personal effort.
The unwanted sound is called noise. This unwanted sound can damage physiological and psychological health. Noise pollution can cause annoyance and aggression, hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects. Furthermore, stress and hypertension are the leading causes to health problems, whereas tinnitus can lead to forgetfulness, severe depression and at times panic attacks.
This type of pollution has become more significant due to technological and industrial developments. We have a duty to stop as fast as possible with this problem because, in the future, would have consequences even more disastrous.
