Sound Pollution

How Loud Is Too Loud ?Noise induced hearing damage

is related to duration and volume of exposure

Safe Exposure limit is 85 Decibels for Eight hours a day

Sound & NoiseSound is a form of energy which is emitted by a

vibrating body and on reaching the ear causes the sensation of hearing through nerves

The frequency limits of audibility are from 20 HZ to 20,000 HZ , Sounds of frequencies less than 20 HZ are called infrasonics and greater than 20,0000 HZ are called ultrasonics

The word noise is derived from the Latin term nausea. It has been defined as unwanted sound, a potential hazard to health and communication dumped into the environment with regard to the adverse effect it may have on unwilling ears

MeasurementThe intensity of sound is measured in sound

pressure levels (SPL) and common unit of measurement is decibel, dB.

The zero on a decibel scale is at the threshold of hearing, the lowest sound pressure that can be heard, on the scale.

on the scale 20 db is whisper, 40 db the noise in a quiet office . 60 db is normal conversation, 80 db is the level at which sound becomes physically painful.

The Noise quantum of some of the cities in our country indicate their pitch in decibel in the nosiest areas of corresponding cities, e.g. Delhi- 80 db, Kolkata - 87,Bombay-85, Chennai-89 db etc.

Sources of Noise The noise pollution has two sources, i.e. industrial

and non- industrial

he industrial source includes the noise from various industries and big machines working at a very high speed and high noise intensity

Non- industrial source of noise includes the noise created by transport/vehicular traffic and the neighborhood noise generated by various noise pollution can also be divided in the categories , namely, natural and manmade

Sources of Noise Road Traffic Noise

Noise from railroads

Control of Noise PollutionNoise Control at Source

Reducing the noise levels from domestic sectors Maintenance of automobiles Control over vibrations Low voice speaking Prohibition on usage of loud speakers Selection of machinery Maintenance of machines

Control of Noise PollutionControl in the transmission path

Installation of barriers Design of building

Installation of panels or enclosures Green belt development

Using protection equipment Job rotation Exposure reduction Hearing protection

Legal Control Constitution of India

Right to Life Right to Information Right to Religion and Noise Directive Principal of State Policy Fundamental Duties

Cr.P.C. Section 133 I.P.C. Public Nuisance 268-295 Law of Torts Noise pollution is considered as civil

wrong Factories Act Reduction of Noise and Oil of

Machinery Motor Vehicle Act. Provision Relation to use of horn

and change of Engine Noise Pollution Control Rule 2000 under

Environment Protection Act 1996

Conclusion We have made the law relating to noise pollution

but there is need to creating general awareness towards the hazardous effects of noise pollution

Particularly, in our country the people generally lack consciousness of the ill effects which noise pollution creates ad how the society including they themselves stand to beneficiary preventing generation and emission of noise pollution

The young children of impressionable age should be motivated to desist from playing with firecrackers, use of high sound producing equipments and instruments on festivals, religious and social functions, family get-togethers and celebrations etc. which cause noise pollution

state must pay its role by the support and cooperation of non-government organizations (NGOs) can also be enlisted.
