Noise pollution is a major problem in Mumbai, with sound levels increasing 10-20 decibels each year. Transportation, construction, industrial activity, and loud speakers are key sources. Festivals like Diwali have recorded noise levels over 100 decibels. Students, the elderly, and those with hearing problems are most affected. While laws have been established, noise levels continue rising in the city, especially during festivals and weddings. The presentation calls for better enforcement of noise regulations to address Mumbai's growing noise pollution issues.

Say!!

4. “
“A form and level of environmental
sound that is generally considered
likely to annoy, distract or
even harm other people.”

5. Now, what is exactly
Noise Pollution?
◇Sound that is unwanted or disrupts one’s
quality of life is called as noise. When there
is lot of noise in the environment, it is
termed as noise pollution.
◇Sound becomes undesirable when it disturbs
the normal activities such as working,
sleeping, and during conversations.

6. BIG problem?!?
Noise Pollution in Mumbai
itself is a big problem, reports
suggesting its growth by 10-20
Db every Upcoming year!!

7. Major Festivals and
the Noise Scale
Ganesh Chaturthi
Survey Showed that
Gnaesh Chaturthi festival
records least among the
three festival as
compared to noise
level..People celebrate
within limits as Noise
level is restricted to
about 85+ Db.
Diwali
Survey showed the
highest Db levels of
noise is recorded during
Diwali festival and it goes
upto 100+Db without any
difficulties.

12. Let’s review some
concepts
DECIBEL
The decibel ( dB) is used to
measure sound level, but it is also
widely used in electronics, signals
and communication. The dB is a
logarithmic way of dscribing a ratio.
The ratio may be power, sound
pressure, voltage or intensity or
several other things.
PITCH
Pitch is perceived as how "low" or
"high" a sound is and represents
the cyclic, repetitive nature of the
vibrations that make up sound. For
simple sounds, pitch relates to the
frequency of the slowest vibration
in the sound
Soundscape
Soundscape is the component of
the acoustic environment that can
be perceived by humans. The
acoustic environment is the
combination of all sounds (whether
audible to humans or not) within a
given area as modified by the
environment.

13. Sources of Noise
Pollution
◇Transportation systems are the main source of
noise pollution in urban areas.
◇Construction of buildings, highways, and streets
cause a lot of noise, due to the usage of air
compressors, bulldozers, loaders, dump trucks, and
pavement breakers.
◇Industrial noise also adds to the already
unfavorable state of noise pollution.
◇Loud speakers, plumbing, boilers, generators, air
conditioners, fans, and vacuum cleaners add to the
existing noise pollution.

14. Solutions for Noise
Pollution
◇Planting bushes and trees in and around sound
generating sources is an effective solution for noise
pollution.
◇Regular servicing and tuning of automobiles can
effectively reduce the noise pollution.
◇Buildings can be designed with suitable noise
absorbing material for the walls, windows, and
ceilings.
◇Regulations should be imposed to restrict the
usage of play loudspeakers in crowded areas and
public places

15. Who are mostly
affected?
￮ Students Having Their crucial exams such as
SSC ,HSC,Third Year Graduates, Students
appearing their civil services exams:IAS,IPS
and so on.
￮ Elderly People ageing anywhere greater than
60 are prone to hearing problems,if only noise
made it more worse than before.
￮ Facts suggest 70% of people <60 are
suffering from hearing problem.

16. How much is
Mumbai Loud??
◇Mumbai suffers it highest noise pollution
during its major festivals..To mention (Ganesh
Chaturthi,Diwali,Navratri)
◇We Mumbaikars love it loud..50% of the
noise complaints are wedding after-parties
which exceeed the time limits.
◇Surveys on Noise Levels shows that Noise
pollution is increasing day by day as people
are more interested in music...Music which is
Loud gives more entertainment, this is the
basic funda.(Graphs show Noise level
ascending through the years.)

17. CONCLUSION
◇So By Completing our project on Noise
Pollution with reference to Mumbai city,we
conclude that our city is endangered by
Vicious NOISES surrounding us, To be fair it
goes on increasing every year with no chance
of reducing anytime soon.
◇Mumbai Police have established certain
laws for helping reduce noise pollution.Their
10:30pm noise warning is a big step towards
this cause.
