Noise is a type of atmospheric pollution. It is one of the public enemies which can neither be seen or rather it can be touched, but it can be listen through the ears and whose growing menace has been increased in the modern age. In today's world the problem of noise pollution has been emerged as one of the serious problems and it has become a serious challenge to the healthy environment.

In fact, the noise of dhol, dhapli, bigul and shankh which is in the root of our Indian culture since the advent of the primitive societies. During the earliest times people used the beat of drums as one of the safest means to protect their life against the wild animals and also used for various religious ceremonies. But in modern days the intensity and frequency of noise has increased so much it is posing a real threat in human life. In this topic, we will be discussing about the meaning, causes of noise pollution and legislative and non-legislative measures to control noise pollution.

Meaning Of Noise Pollution:

The term 'Noise Pollution' has not been defined anywhere in the central legislative. But however, the term has been described in the Environmental Protection Act. 1986 as an environmental pollutant and empowers the central government to frame rules prescribing the maximum permissible limits for noise in different areas.[1]

The word noise has been derived from the Latin word nausea. It has been defined as unwanted sound, a potential health hazard tom health and communication dumped into environment without regard to the adverse effect it may on unwilling ears.

Pollution is a noun which is derived from the word pollute. Sec 2(c) of the Environmental protection Act of 1986 defines �environmental pollution� as an environmental pollutant to mean any solid, liquid and gaseous substance present in the such type as it may intend to cause some harmful effect from it.

From this we could say that noise is an unpleasant sound and when it comes to the public and causes some harmful effects to the environment then it will be stated as Noise pollution.

Permissible noise level in India
In industrial areas, the permissible limit is particularly 75 dB for daytime and 70 dB at night. In commercial areas, it is 65 dB and 55 dB, while in residential areas it is 55 dB and 45 dB during daytime and night respectively.

Causes of Noise Pollution:
Particularly speaking about the noise pollution, they have been classified under two categories such as:

Right to life is a fundamental right under Article 21 of the Indian constitution and it includes the right of enjoyment of pollution free water and air for full enjoyment of life.

In the case of T Damodar Rao v Municipal Corporation Hyderabad,[4]
The supreme court observed that The slow poisioning by the polluted atmosphere caused by environmental pollution and spoilation should also be regarded as amounting to violation of Art 21, of the Indian constitution.
