It affects the peace of mind and invades the privacy of a human being.

Most of us are accustomed to the sounds we hear every day. However, when the sound of the television keeps you from sleeping all night or the traffic starts giving you a headache, it transcends the boundaries of mere noise and qualifies as noise pollution. However, the noise that tends to disrupt the natural rhythm of life makes for one of the biggest pollutants. By definition, noise pollution takes place when there is either an excessive amount of noise or an unpleasant sound that causes a temporary disruption in the natural balance. This definition is usually applicable to sounds or noises that are unnatural in either their volume or their production. Our environment is such that it has become difficult to escape the noise. Even electrical appliances at home have a constant hum or beeping sound.

Noise pollution , unwanted or excessive sound that can have deleterious effects on human health, wildlife, and environmental quality. Noise pollution is commonly generated inside many industrial facilities and some other workplaces, but it also comes from highway, railway, and airplane traffic and from outdoor construction activities. Sound waves are vibrations of air molecules carried from a noise source to the ear. Sound is typically described in terms of the loudness amplitude and the pitch frequency of the wave. Loudness also called sound pressure level, or SPL is measured in logarithmic units called decibels dB. The normal human ear can detect sounds that range between 0 dB hearing threshold and about dB, with sounds between dB and dB causing pain pain threshold.

Noise is defined as unwanted sound. Environmental noise consists of all the unwanted sounds in our communities except that which originates in the workplace. Environmental noise pollution, a form of air pollution, is a threat to health and well-being. It is more severe and widespread than ever before, and it will continue to increase in magnitude and severity because of population growth, urbanization, and the associated growth in the use of increasingly powerful, varied, and highly mobile sources of noise.
Noise pollution , also known as environmental noise or sound pollution , is the propagation of noise with ranging impacts on the activity of human or animal life, most of them harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport, and propagation systems. Some of the main sources of noise in residential areas include loud music , transportation traffic, rail, airplanes, etc. Documented problems associated with noise in urban environments go back as far as ancient Rome.
Atmospheric pollution is not the only type of contamination that is harming living beings on the planet. And according to the European Environment Agency EEA , noise is responsible for 16, premature deaths and more than 72, hospitalisations every year in Europe alone. According to the WHO, noise is harmful when it exceeds 75 decibels dB and feels painful at levels above dB.
