Effects Of Noise Pollution On Children's Health

Most of us do not even understand the concept of noise pollution. While most of us know about the ill effects of environmental pollution, very few among us are aware of the dangers of noise pollution as it has received the least attention. Read on to know the causes and effects of noise pollution on children's health.

In India, over the years, noise pollution has posed a major threat to human and environmental health. Not surprisingly, research shows that India is the global capital of noise pollution, with Mumbai being categorised as one of the noisiest cities in the world. Understanding the growing menace, India's Central Pollution Control Board (CPCB) came up with an exclusive plan in 2011 to monitor, document and control noise pollution across various cities in India. According to the data obtained as part of this initiative between 2011 and 2014, Mumbai exceeded the prescribed limits for noise pollution and was seen at alarming noise levels quite consistently. Not far behind were cities like Hyderabad, Delhi, and Chennai with very high levels of noise pollution.

Effects Of Noise Pollution On Children's Health

Noise pollution can have moderate to severe impacts on the health of human beings, especially children. It can be both physiological and psychological, according to experts. Karl D Kryter in his book, 'The Handbook of Hearing and the Effects of Noise: Physiology, Psychology and Public Health' mentions, "Noise pollution can cause annoyance, hypertension, high stress levels, tinnitus, hearing loss and other harmful effects."

According to the CPCB report (2016) high noise levels can contribute to cardiovascular effects while exposure to moderately high levels can cause a rise in blood pressure. "As children spend more time in bed than adults, they are more exposed to night noise. Impairment of early childhood development and education, caused by noise, may have lifelong effects on academic achievement and health," says the World Health Organization in their report, 'Guidelines for community noise, 1999'.

According to the WHO, studies on the effects of chronic exposure to aircraft noise on children have found that consistent exposure harms their cognitive performance. WHO also states that studies have found moderate evidence of effects on blood pressure and catecholamine (which is produced by the adrenal gland and plays an important role in the body's physiological response to stress) secretion.

Possible damage to a kid's health

  • Threshold shift in hearing because of constant exposure to loud noise
  • Old age deafness as a cumulative effect of long-term exposure
  • Tinnitus - buzzing in the ear
  • Lack of concentration
  • Decreased memory
  • Inability to do skilled work
  • Loss of sleep and irritability
  • Poor academic performance
  • Psychiatric illness and seizure

Solutions to curb noise pollution

Unfortunately, unlike in the case of water pollution, we cannot take too many individual measures to protect ourselves from noise pollution. What is needed is community action to insist on governments and authorities to implement pollution control norms.

The urban development authority of every city, in its master plan, clearly segregates and separates noisy and polluting industries from residential areas. However, deviations from the master plan are rampant across India, resulting in industries and commercial spaces being established in residential areas. This is a primary cause for increase in noise pollution. Community action is needed to insist the authorities to follow the master plan. Construction of sound-proof rooms for extremely noisy industries may also be a viable solution.

While motor vehicles with jarring sounds for horns and damaged exhaust pipes are banned, they still continue to plague our cities. These sharp sounds can have severe impacts. Strict enforcement of laws and increase and maintenance of 'no horn' silence zones near schools and hospitals can be effective.

Creation of buffer zones, with trees along the roads in residential areas, is a good way to combat noise pollution as trees absorb sound. With several elements vying for the top spot in the list of things that are harmful to your health, it's your responsibility to keep noise off the list. Make sure you take steps to reduce noise pollution before it can have an irreversible impact on your health. As the adage goes, prevention is definitely better than cure!

Ways to control noise pollution at home:

Power Off: Electronic devices like TV, mobile phones and music systems are the primary sources of noise inside our homes. Strictly regulate time spent on these devices as at some level, your brain can convert even normal sounds into white noise and prove to be harmful.

Noise-cancelling headphones: These are not permanent solutions; but a pair of these while on the move through really noisy areas can help avoid the immediate effects.

Unplug those earphones: Using earphones to listen to music over long periods can again convert the music to noise in your brain, causing detrimental effects.

Equip your home: If you live near an airport or industries, equip your home space to deal with all that noise. Install basic noise protection facilities like rubber-insulated windows and doors to keep the noise away.

India is the global capital of noise pollution, with Mumbai being categorised as one of the noisiest cities in the world.

Sources of noise pollution

Traffic: Automobiles, trains, aeroplanes

Social: Loudspeakers, social and religious ceremonies

Industrial: Factories, construction activities, machinery

Home: High decibel music, home appliances

150 dB = fireworks at 3 feet

140 dB = firearms, jet engine

130 dB = jackhammer

120 dB = jet plane take-off, siren

Extremely Loud

110 dB = maximum output of some MP3 players, model airplane, chain-saw

106 dB = gas lawn mower, snow blower

100 dB = hand drill, pneumatic drill

90 dB = subway, passing motorcycle

Very Loud

80-90 dB = blow-dryer, kitchen blender, food processor

70 dB = busy traffic, vacuum cleaner, alarm clock


60 dB = typical conversation, dishwasher, clothes dryer

50 dB = moderate rainfall

40 dB = quiet room


30 dB = whisper, quiet library

Expert speak

"Noise pollution can cause long-term health problems. High impact noise, such as fireworks, can cause permanent loss of hearing. Such problems are acute during the festival season. Last year, during Deepavali, about 5-6 children came to me with problems like ringing in the ear.

The problem with noise pollution is that it manifests as a neural disease that can be irreversible. By 50 years of age, people exposed to severe noise may permanently lose hearing. This can affect them adversely in many ways, including being a hindrance to social interactions.

But, the effects of noise pollution can be mitigated easily. People who are exposed to excessive noise can take a break of 2-4 hours in-between to prevent major damage. It might be difficult to control noise production; but, it is very easy to prevent exposure to noise. You can do that by wearing ear muffs or ear plugs.- Dr D Balakrishnan, Head of Department, Audiology, SRM University
