Keep in mind that the “Pure Tone” noise pollution on the so called Smart Grid is not supposed to be in our air, EVER!!  We are the pioneers of something that has NEVER been studied.  You will note that when the experts write about noise; it has always been a localized issue; not a global one…..Sandaura

Now a day, noise pollution is not a new problem for common man, especially in most of the industrial towns and metropolitans cities. Noise pollution means any sound that is undesired by the recipient. The effect of sound on human depends upon its frequency. Human ear are known to be sensitive to an extremely wide range of intensity varied from 0 to 180 dB. The noise is generated by the human through various ways. In present research article, various sources of noise pollution, measurement of noise, dB scale, equipments used in the measurement of noise levels, impacts of noise, adverse health effects of noise pollution, control of indoor noise, control technologies available for noise pollution and Indian penal codes to prevent noise pollution are the main points of focus of attention. Noise must be controlled and prevented by using various effective techniques at the source itself is today’s need. The objective of this research work is to know about the various ways of generation of noise, their effects on human, its prevention and control.

Key Words : Noise Pollution, Hypertension, Prevention, Human being, dB scale, Impacts of noise


The word noise is derived from the Latin word nausea. Noise means wrong sound in the wrong place at the wrong time. Noise pollution may be defined as unwanted sound which gets damped into the atmosphere without regarding to the adverse effects it may have.1-4 Different people have not affected equally by the same noise. There occurs a vast variation in the individual sensitivity to sound and people are affected differently when they are at home and when they are at work. Sound is measured by several complex systems, but the best known unit of measurement is the decibel (dB). Some peoples can hear frequencies that others are not able to detect.

Sources of noise pollution include inter alia, vehicular traffic, neighborhood, electrical appliances, TV and music systems, public address systems, railway and air traffic and electricity generating sets. Most of the people inhabiting metropolitan cities or big towns and those working in factories are susceptible to the adverse effects of noise. The problem of noise pollution is less in small towns and villages. But, those residing in villages or towns along the national or state highways or close to railway tracks do bear the burnt of excessive noise. Indiscriminate use of horn by the vehicles and widespread use of loud speakers in Indian social and religious ceremonies cause several health hazards to the urban inhabitants. It may cause deafness, nervous breakdown, mental disorder, heart troubles and high blood pressure, head-aches, dizziness, inefficiency and insomnia.5 Though noise pollution is a slow and subtle killer, yet very little efforts have been made to ameliorate the same. It is along with other types of pollution has become a hazard to quality of life. Kiernan finds that an even relatively low level of noise affects human health adversely. It may cause hypertension, disrupt sleep and hinder cognitive development in children.6 The effects of excessive noise could be so severe that either there is a permanent loss of memory or a psychiatric disorder.7 Thus, there are many an adverse effects of excessive noise or sudden exposure to noise.
