Pollution can be simply defined as anything that disrupts the environment. Disruption could be of any nature: Chemical, radiation, visual or even disturbance in the peace and quiet. The latter, contributes to noise pollution. Noise pollution can be designed as any unwanted noise or disturbing sound that disrupts day to day activities and in turn compromises the quality of life. Various health problems can arise from chronic exposure to higher decibels of sound. These health problems include higher blood pressure, cardiovascular issues leading to an increased risk of heart attacks. As unlikely as it might seem, deep-seated physiological effects might also occur due to long term exposure to noise pollution.

Noise pollution is the regular exposure to elevated sound levels that may cause adverse effects in humans or other living organisms. According to the World Health Organization, sound levels less than 70 dB are not cause any damage to the living organisms, regardless of how long or consistent the exposure is.

Exposure to noise for more than 8 hours to constant noise beyond 85 dB may be hazardous. That means, if you are at a place for 8 hours daily in close proximity to a busy road or highway, you are very likely exposed to traffic noise pollution around 85dB. Noise pollution is said to take place when there is either excessive amount of noise or an unpleasant sound that causes temporary disruption in the natural balance. We have created an environment that just cannot escape noise. Our television, mixer grinder etc. all of those electrical gadgets cause noise. Causes and effects of noise pollution are plenty. We need to do our bit to save the earth and the humans from further damage.

Noise pollution is supposed to have many deleterious effects on both our brain and body.

As per the parameters set by World Health Organization (WHO), the permissible upper limit of sound in any given environment should not exceed 45 dB. In city environment, this upper limit is violated way too often. The major contributing factors to noise pollution happen to arise out of: all types of means of transports, industrial setup and loud music.
