Noise Pollution refers to the presence of sound beyond a permissible limit, so as to harm humans and animals. Some of the common sources of noise pollution are machines, heavy machineries, factories, transportation vehicles, aircrafts, trains etc. Unorganized settlements, resulting in traffic jams are also a main cause of noise pollution. Noise has severe health and psychological impacts on humans and animals. It has been known to cause severe cardiovascular problems in humans. Incidents have also been noted when animals got scared and confused by noise, and behaving in a strange manner. Birds are also known to leave their roosters in panic when they hear a loud noise.
