Noise pollution has negative effects on marine animals, human health, and work efficiency. It can damage the nervous systems of animals like cows, decreasing their milk production by 15%. Excessive noise also negatively impacts marine animals and disrupts the food chain. In humans, noise pollution can cause diseases like high blood pressure and mental illness, as well as hearing loss and sleep problems. It decreases people's concentration at work, making tasks take longer to complete and causing fatigue. Reducing noise pollution requires avoiding unnecessary car horns and loud music, wearing earplugs, and choosing quieter modes of transportation when possible.

3. Introduction
• What is noise pollution ?
Noise Nauseas (Latin word)
disgust & discomfort
• Sound VS Noise
Sound: a form of energy that is transmitted by pressure
variations which the human ear can detect.
Noise: unwanted sound

4. Sound waves of equal amplitude with increasing frequency from
top to bottom

5. Noise intensity
is measured in
decibel units

6. The source of noise
Transportations & Industry

7. Main point 1
Having effects on animals
Damage the nervous system of the animals
e.g decrease a cow's capacity of milk production
15% 1999-2001
Having a negative impact on the
whole marine animals about food chain
oil-drilling

8. Main point 2
Affecting the general health and hearing
power of the human beings
Getting certain diseases like blood pressure,
mental illness and bad sleep
hearing impairment, hypertension, ischemic
heart disease, annoyance & sleep disturbance.
Having hearing difficulties
• damage to hair cells

9. Main point 3
Decreasing in the efficiency of working
Affecting the concentration required for
doing a work
People need to devote more time to
complete their task which lead to tiredness and
fatigue because of lack of concentration

10. Conclusion
Noise pollution the risk role in our life
How to reduce the noise pollution by yourself?
Understand what causes noise pollution
avoid the noise pollution by yourself :
Do not use car horns unnecessarily.
Avoid loud music
Wearing earplugs to prevent loss of hearing.
