2. What is Noise Pollution?
• By definition, noise pollution takes place when there is
either an excessive amount of noise or an unpleasant
sound that causes a temporary disruption in the natural
balance. This definition is usually applicable to sounds or
noises that are unnatural in either their volume or their
production

3. INTRODUCTION
• Noise Pollution in Mumbai is a big problem.
• The biggest problem in Mumbai is high population density.
High rises on both sides of the road limit the dispersion of
sound.
• Just like the case of any metro city, along with the traffic
comes the unnecessary incessant honking. Indians use the horn
much more than their counterparts in western countries.
• Prolonged exposure to incessant honking with high sound
decibel levels can lead to a lot of health issues in people.
According to a World Health Organization (WHO) report, this
sound pollution has created hearing related disorders in 6 per
cent of Indians such as hearing impairment, tinnitus, ear ache,
hearing loss, etc.

day stood at 85.8dB, while that from a commercial space
was 83.2dB.

capable of producing a large amount of noise.

factories and industries are exposed to high levels of
noise even after wearing earplugs to minimize the effect

effects.
• According to study reports (2016) high noise levels can
contribute to cardiovascular effects while exposure to
moderately high levels can cause a rise in blood pressure.

14. Possible damage to a
child’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

their survival depends on it. The ill effects of excessive
noise begin at home. Pets react more aggressively in
households where there is a constant noise.

behavioral problems. In nature, animals may suffer from
hearing loss, which makes them easy prey. Others
become inefficient at hunting, disturbing the balance of
the eco-system.
