Sound or noise pollution refers to the excessive noise that interferes with normal activities, potentially leading to a lower quality of life. The main sources of noise pollution include machines and mechanical equipment, fireworks, vehicles, music performances and emergency sirens.
Noise pollution is unpleasant and harmful. Constant exposure to noise pollution disrupts one's sleep, leading to decreased productivity, irritability and fatigue. Noise pollution is also associated with more severe health problems, including high stress levels, tinnitus, depression and panic attacks. People who work in or must be present in areas affected by noise pollution should wear a form of hearing protection, such as ear plugs.
