Learning how noise pollution can effect our society and environment

1. NOISE
POLLUTION

2. INTRODUCTION
Noise pollution, also known as environmental noise, is the
propagation of noise with harmful impact on the activity
of human or animal life.

3. THE
SOURCE OF
NOISE
POLLUTION
Noise in the
street
Construction
site noise
Noise at work
place
Transport
noise

4. Noise in the street
– Types of street noise include vehicle
noise from repairs and alarms,
loudspeakers and burglar alarms. Traffic
noise, noise made by military forces, or
from campaigning demonstrations is
excluded.

5. Construction site noise
– This covers building works, road works,
demolition work and dredging.

6. Noise at work place
– This cover in the industrial where the
worker are expose to high level of sound
from the machine.

7. Transport noise
– Includes road traffic, aircraft and railway
noise.

8. NOISE POLLUTION EFFECT

9. HEALTH
Hearing loss
•exposure to moderately high levels of environmental noise
contributes to hearing loss.
•can be caused by outside (e.g. trains) or inside (e.g. music) noise.
Cardiovascular effects
•exposure to moderately high levels during a single eight-hour
period causes a statistical rise in blood pressure of five to ten points
Stress
•victims of domestic disturbances claim high level sound have left
them unable to sleep or made them stressed
•noisy neighbors have made their life a misery and they cannot
enjoy their own homes

10. Annoyance
•the level of annoyance and the relationship between noise
levels and resulting health symptoms could be influenced by
the quality of interpersonal relationships at the workplace
Child physical development
•Specific birth abnormalities included harelip, cleft palate, and
defects in the spine cause by the exposed to elevated sound
levels.
Cognitive development
•When young children are regularly exposed to levels of noise
that interfere with speech, they may develop speech or
reading difficulties, because auditory processing functions are
compromised

11. Wildlife
Carcinus maenas
•Marine invertebrates, such as crabs
(Carcinus maenas), have also been
shown to be negatively affected by ship
noise. Repeated exposure to the sounds
did lead to acclimatization.
European Robins
•European robins living in urban
environments are more likely to sing at
night in places with high levels of noise
pollution during the day, suggesting that
they sing at night because it is quieter,
and their message can propagate
through the environment more clearly
Whale
•Noise pollution may have caused the
death of certain species of whales
that beached themselves after being
exposed to the loud sound of military
sonar.

12. Challenge from the noise
pollution
Urban noise affects more than quality of life issue; the level of noise in many
cities can cause serious and long-term harm to health
Noise not only makes hearing, concentrating, and working more difficult,
Noise interferes with cognitive functions, including attention, concentration,
memory, reading ability, and sound discrimination. The long-term
consequences of these effects on children ‘s development are particularly
significant.
Long term exposure to noise from road, rail, and air traffic results in
physiological and psychological stress, which indirectly may contribute to
heart disease, and high blood pressure.
Chronic or repeated exposure to sounds at or above 85 decibels can cause
hearing loss.

13. Solution to overcome the
challenge
Improve your
insulation
Invest in noise-
canceling device
Put on earplugs
when doing work
Using the personal
protective
equipment when
handling the
machine
Be creative with
the office or house
layout
Plant more trees in
the urban city
Creating
awareness and
education on the
consequences of
noise pollution

14. Potential unethical
problem
Do
Follow the regulation on
personal protective
equipment when
working.
Use noise protection like
ear plugs when needed.
Be alert and aware
about the sound
permissible limit
exposure in work place
Don’t
Employer not providing
personal protective
equipment in the work
place.
carry out noisy DIY work
after 8pm or before 8am
on weekends
Attitude to ignore the
early warnings.
