Noise pollution, or sound pollution, is the propagation of noise or sound with potential harmful effects on humans and animals. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems. Poor urban planning may give rise to noise disintegration or pollution.
Causes of noise pollution
Urban traffic:
A major source, especially in cities, caused by vehicle volume, road surfaces, tire friction, and driver behavior.
Industrial machinery:
Manufacturing plants and factories generate high-decibel sounds from their equipment.
Aviation:
Noise from airports and flight paths, particularly during takeoff and landing, is a major source of pollution.
Household devices:
Everyday appliances, as well as loud music systems and televisions, contribute to indoor and outdoor noise.
Social events:
Loudspeakers and fireworks, especially during celebrations, are significant contributors.
Effects of noise pollution
On humans:
Hearing damage:
Prolonged exposure to high noise levels can cause temporary or permanent hearing loss.
Cardiovascular issues:
Noise pollution is linked to high blood pressure, increased heart rate, and a higher risk of coronary artery disease.
Psychological effects:
It can lead to stress, anxiety, irritability, and sleep disturbances.

Conclusion:
Noise pollution is a significant environmental and public health concern caused by excessive and unwanted sound from sources like traffic, industries, construction, and loudspeakers.
It leads to serious health issues including hearing loss, increased stress, high blood pressure, sleep disturbances, and reduced concentration, affecting both humans and wildlife.
