Noise pollution

Noise pollution doesn't have any impacts on people's health, but above all, it is annoying and irritating. It is still very much disregarded by people, just as light pollution.

Noise pollution contaminants are not physical particles, but rather waves that interfere with naturally-occurring waves of a similar type in the same environment. Thus, the definition of noise pollution is open to debate, and there is no clear border as to which sounds may constitute noise pollution.

The prevailing source of artificial noise pollution is from transportation. In urban areas, automobile, motorcycle, and even entertainment noise can cause sleep disruption in humans and animals, hearing loss, heart disease (as a result of stress), and in severe cases even mental instability.

Altough most nations have government agencies responsible for different types of pollution, none has one that regulates noise pollution.
