Question

What are the harmful effects of noise pollution?

Answer 1

• Hearing damage (temporary or permanent): Tinnitus and partial or complete deafness from prolonged/high-level exposure.
• Sleep disturbance and fatigue: night noise disrupts restorative sleep, causing daytime sleepiness and reduced recovery from stress.
• Impaired communication and reduced concentration: Interfere with speech, learning, school performance, and workplace efficiency.
• Physiological and cardiovascular effects: Chronic noise raises stress, pulse, and blood pressure and is linked to headaches, nausea, and higher cardiovascular risk.
• Mental-health and annoyance effects: increased irritability, anxiety, emotional distress, and reduced overall well‑being.
• Harm to animals and wildlife: disruption of feeding, breeding, migration, and communication; some birds avoid noisy areas or stop laying eggs, and severe noise can cause miscarriage in some animals.
• Damage to buildings and cultural monuments: Very high intensity noise or explosions can crack stone, glass, and structures.
