Noise pollution is a neglected environmental concern that has various sources and negative effects. It is measured in decibels and comes from transportation, industries, loud speakers, and other sources. Noise pollution negatively impacts humans, animals, and aquatic life by causing health issues like hearing loss, heart attacks, and stress as well as disrupting behavior and communication. While strategies exist to control noise like soundproofing and locating industries away from residents, noise pollution remains neglected due to its invisibility, indirect effects, and lack of awareness. The document calls for stricter laws, new technologies, more awareness, and sustainable solutions to address noise pollution.

5. Sources of Noise Pollution
• Transportation system
• Industrial Noise
• Loud Speakers
• Construction sites
• Household noise
• Ships and Oil fields

6. Measurement of Noise Pollution
• A Decibel is the standard for the measurement of
noise.
20 db is whisper
40 db the noise in a quite office
60 db is the Normal conversation
80 db is the Level where sound
becomes Physically painful

8. Effect of Noise Pollution on Humans
•Mental Illness
•Changes in Immunity system
•Heart attack
•Hearing loss
•Sleep Disturbance
•Increase in stress
•Birth defects

9. Effects of Noise Pollution on Animals
• Hearing Loss
• Masking
• Psychological Effects
• Behavioral Effects
• Ecological Effects

10. Effect of Noise pollution on Aquatic Life
• Complexity in Communication
• Complexity in Reproduction
System
• Change in behavior
• Complexity in Hunting
• Affect in Nervous System
• Radiation of Radioactive Waves

11. Noise Control Strategy
• Planting more Trees
• Noise Absorbing materials in Building
• Workers should be provided with equipment (ear
plug, ear muffs etc)
• Sound proof doors & windows
• Factories & Industry should be located far from
residential areas
• Social Awareness Programs

12. Why Noise Pollution is Neglected?
• Invisible
• Indirect Effect
• Inefficient Awareness

13. Conclusion
• Imposing Laws Strictly
• Use Updated Technologies that
make less sound
• Increasing Social Awareness
• Using more sustainable transport
system

Are we ever going to get rid off
Noise Pollution?
