Noise pollution refers to unwanted sound that can cause discomfort or health issues. It is measured in decibels and common sources include industrial machines, vehicles, construction activities, and social events playing loud music. Prolonged exposure to noise pollution can lead to hearing loss, sleep issues, cardiovascular problems, and stress. It also negatively impacts wildlife that rely on sound. Reducing personal sound usage and better urban planning can help control noise pollution.

3. Noise Pollution
 Noise pollution refers to undesirable sound.
 Sound which generates horrible discomfort on ear.
 Also known as Environmental noise or Sound
pollution.

4. NOISE
 Noise
• Any unwanted sound that do not need or want to hear.
• It is measured in decibels dB
• Average noise level is 97.60dB
• Normal speech has a sound level of approximately 60dB
• Sound above 120dB can cause discomfort to ears

6. TYPES OF NOISE POLLUTION
 Continuous Noise
 Intermitted Noise
 Impulsive Noise
 Low Frequency Noise

7. TYPES OF NOISE POLLUTION
 Continuous Noise
 Noise that produced continuously without interruption
 This could came from
 factory equipments
 Heating system
 Ventilation system

8. TYPES OF NOISE POLLUTION
 Intermitted Noise
 It is a mix of quiet and noisy periods
 Most manufacturing noise is intermitted
 Noise level increases or decreases rapidly

9. TYPES OF NOISE POLLUTION
 Impulsive Noise
 Commonly associated with construction and demolition
industry
 Created by
 explosion
 construction equipments such as pile driver

10. TYPES OF NOISE POLLUTION
 Low Frequency Noise
 Sounds lower in frequency than 20Hz

11. CAUSES OF NOISE POLLUTION
 Industrialization
 Poor Urban Planning
 Social Events
 Transportation
 Construction Activities
 Household Chores

12. CAUSES OF NOISE POLLUTION
 Industrialization
 Most of the industries use big machines which produced
large amount of noise
 Various Equipments like Generators, Exhaust Fans
Grinding Mills also produce big noise

14. CAUSES OF NOISE POLLUTION
 Workers in industries and factories wear ear plugs to
minimize the effect of noise

15. CAUSES OF NOISE POLLUTION
 Poor Urban Planning
 In most developing
countries poor urbanization
also play a vital role in noise
pollution which disrupt the
environment of society
 Congested Houses
 Large families share small
houses

16. CAUSES OF NOISE POLLUTION
 Social Events
 Noise is at its peak in most of social events people play
sounds on full volume makes the condition of people
living nearby pretty worse
 Weather it is marriage, parties, worship places loud
sound in markets

18. CAUSES OF NOISE POLLUTION
 Transportation
 large number of
vehicles on roads,
airplanes flying over
houses,
underground trains
produced heavy
noise

19. CAUSES OF NOISE POLLUTION
 Construction Activities
 under construction
activities like mining,
construction of
bridges, dams,
building, stations,
roads, flyovers take
place everyday to
reduce traffic
congestion

20. CAUSES OF NOISE POLLUTION
 Household Chores
 We are surrounded by gadgets and use them extensively
in our daily life
 Gadgets like: TV, Mobile, Mixer grinder, Pressure cooker,
vacuum Cleaner, Washing Machine, Dryer and Air
Conditioners are minor contributions to noise but
affects the quality of life.

22. EFFECTS OF NOISE POLLUTION
 Hearing Problems
 Health Issues
 Sleeping Disorders
 Cardiovascular Disease
 Communication Problems
 Effects On Wildlife

24. EFFECTS OF NOISE POLLUTION
 Hearing problems
 Any unwanted sound that our ear have not been built to
filter can cause problems within body
 Our ears can take a certain range of sound without
getting damaged
 Man made noises such as jackhammers, horns even
vehicles can also be too loud for hearing range

25. EFFECTS OF NOISE POLLUTION
 Constant exposure to loud sounds can easily result in
the damage of our ear drums and loss of hearing

26. EFFECTS OF NOISE POLLUTION
 Health Issues
 Excessive noise pollution in working areas such as
offices, construction sites, bars and even in homes can
influence psychological health.
 Studies show that occurrence of aggressive behavior,
disturbance of sleep, constant stress, fatigue and
hypertension are linked to excessive noise level
 Can cause more severe and chronic health issues

28. EFFECTS OF NOISE POLLUTION
 Sleeping Disorder
 Noise can certainly
hamper your
sleeping pattern and
may lead to
irritation and
uncomfortable
situations

29. EFFECTS OF NOISE POLLUTION
 Cardiovascular Issues
 Blood pressure levels and stress related to heart
problems are on rise due to noise pollution
 High intensity noise cause high blood pressure and
increase heart beat rate as it disrupt normal blood flow

31. EFFECTS OF NOISE POLLUTION
 Communication problems
 high decibel noise can put trouble and may not allow
people to communicate freely this may lead to
misunderstanding
 Constant sharp noise can give you headache and disturb
your emotional balance

32. EFFECTS OF NOISE POLLUTION
 Effect On Wildlife
 Wildlife faces more problems than humans because
they are more dependent on sounds.
 Animals have a better sense of hearing than us since
their survival depends on it.
 Pets react more aggressively in household where there is
constant noise

34. EFFECTS OF NOISE POLLUTION
 Species that depend on mating calls to reproduce are
often unable to hear there calls due to extreme man
made noise
 Some animals require sound waves to echo locate and
find their way when migrating disturbing their sound
signals means they get lost easily.

35. NOISE POLLUTION CAN BE
CONTROLED
 There is no any solution to reduce noise pollution
 On personal level everybody can help reducing noise
in their homes by lowering the volume of the radio,
music system and television
 Removal of public loudspeakers is another way

36. NOISE POLLUTION CAN BE
CONTROLED
 Controlling sound levels in clubs, bars, parties and
disco
 Better urbanization can help to reduce noise
 Machines can be placed away from residential areas
 Moving away from noisy areas.
