Explanation:

Noise pollution can cause hearing - loss due to damage of hair cells in the inner ear. It can also lead to stress - related health issues like high blood pressure as it triggers the body's stress response. Sleep disturbances occur as noise disrupts sleep cycles. Reasons include increased industrial activities with machinery noise, heavy traffic on roads with vehicle horns and engines, and noisy construction work. These sources emit high - decibel sounds that are harmful to human health and the environment.

Answer:

Adverse effects of noise pollution:

• Hearing loss: Prolonged exposure to loud noise can damage the hair cells in the inner ear, leading to permanent hearing impairment.
• Stress - related health issues: Noise pollution triggers the body's stress response, which can result in high blood pressure, increased heart rate, and other cardiovascular problems.
• Sleep disturbances: Noise can disrupt sleep cycles, leading to insomnia, fatigue, and decreased productivity.

Reasons for noise pollution:

• Industrial activities: Factories, power plants, and other industrial facilities often emit high - decibel sounds from machinery, generators, and other equipment.
• Traffic: Heavy traffic on roads, railways, and airports generates significant noise from vehicle horns, engines, and aircraft.
• Construction work: Building and infrastructure projects produce loud noises from construction equipment, demolition, and excavation.
