POLLUTION
I. INTRODUCTION
1.Definition
Noise pollution is the presence of
unwanted, disturbing, or harmful
sounds in the environment that
interfere with everyday activities
and affect both humans and
animals.
2. The importance of topic
Noise pollution, though invisible, poses serious
threats to human health, ecosystems, and urban
quality of life.
Understanding and addressing noise pollution is
crucial to improving public health, creating more
peaceful living environments and making cities more
livable.
II. Sources of
Noise Pollution
Urban and Transportation Noise
Industrial and Occupational Noise
Recreational and Domestic Noise
Technological Sources
II.Sources of Noise Pollution
1. Urban and Transportation Noise
Urban road traffic operates incessantly, especially during
peak hours
Railway transportation generates significant noise
pollution as trains move
In areas near airports, residents are subjected to intense
noise from aircraft engines during takeoff and landing
TRANSPORTATION NOISE

II.Sources of Noise Pollution
2.Industrial and Occupational Noise
In industrial zones and construction sites, noise from
heavy machinery is inevitable
The loud sound of equipment running all day, along with
metal hitting each other makes the work environment stressful
II.Sources of Noise Pollution
3. Recreational and Domestic Noise
Loud music, parties, and home
appliances:
In daily life, recreational activities
are common sources of noise
pollution
II.Sources of Noise Pollution
4. Technological Sources
Mobile devices, alarms, and advertisements:
Alarm tones and notification sounds from
smartphones contribute to sound overload
III. Effects of Noise
Pollution
1. Human Health
2. Environmental Impact
3. Social and Economic Consequences
III. Effects of Noise Pollution
1. Human Health
Physical Health
Hearing loss: Do long-term exposure to noise above 85
decibels.
Sleep disturbance: Noise at night affects sleep quality →
fatigue, low immunity.
III. Effects of Noise Pollution
1. Human Health
Mental Health
Stress: Constant exposure to noise increases cortisol levels
(the stress hormone)-> irritability and emotional instability.
Reduced concentration: Students and professionals
working in noisy conditions often suffer from reduced
attention span, memory issues, and poor cognitive
performance.
III. Effects of Noise Pollution
2. Environmental Impact
Wildlife Migration
disturbance disruption
Affects communication, Noise affects natural
mating, feeding migration paths → risks
(especially birds & marine survival of species.
animals).
III. Effects of Noise Pollution
3. Social and Economic Consequences
Noise distracts workers, Treating stress, heart
reduces efficiency, and problems, hearing loss costs
increases errors in tasks, time and money.
ultimately lowering output

Reduced productivity Healthcare costs
IV. Real-Life Examples of
Noise Pollution
NOISE IN BIG CITIES
NEW MUMBAI
YORK
• Traffic, sirens,
construction, and the • Heavy traffic, street
subway system. vendors, festivals
• NYC: Up to 85 dB in
busy areas
AIRPORT NOISE
Heathrow, LAX & Tân Sơn Nhất
•Aircraft takeoffs/landings near
homes
• Night flights disturb sleep
Construction • Rapid urbanization =
Noise in Cities nonstop building
New apartment buildings,
roads, and commercial centers
• Loud machines (drills,
cranes) from morning to night
V. Solutions
1. Government and policy measures
Noise regulation laws and Urban planning and noise
zoning rules barriers
Noise regulation laws: set legal limits for Design urban spaces to minimize noise
acceptable noise levels in residential, exposure by creating buffer zones
commercial, and industrial zones Moving noisy infrastructure away from
Zoning rules: separate noisy areas (e.g., homes
factories, highways) from quieter Constructing physical barriers (e.g., walls,
residential neighborhoods acoustic fences) along highways or railway
lines
V. Solutions
2. Technological and engineering solutions
Quieter machinery, Green buffers like trees and
soundproofing buildings vegetation
Quieter machinery: reduce noise at the
source Dense vegetation can absorb and diffuse
sound waves, improving both acoustic
Soundproofing buildings: shield residents and air quality
from external noise
V. Solutions
3. Community and personal actions
Reducing personal noise Public awareness
output campaigns
Lower music volume
Raise awareness about the effects of
Avoid excessive use of car horns noise pollution and promote respectful
Limit noisy activities (e.g., drilling, parties) noise behavior in the community.
to appropriate times
VI. Conclusion
Noise pollution is unwanted or harmful noise that
has negative impacts on both humans and animals.
Common sources:
- Traffic ( cars, trucks, trains, airplanes…)
- Construction sites
- Machinery, equipment
- Loud music, parties, and home appliances
- Conversations
VI. Conclusion
Noise pollution has serious consequences, affecting
human health, mental well-being, the environment, and
even the economy.
Solutions:
Enforce noise laws and proper zoning
Smart urban planning
Use quiet tech, soundproofing and green buffers
Raise public awareness and reduce personal noise
