What is Noise Pollution?
DEFINITION
Noise pollution refers to the excessive or disturbing noise that interferes with normal activities,
such as working, sleeping, commuting, conversing, etc.
-Detrimental effects on human health and well-being;
-Negatively impacts quality of life;
-Disrupts ecosystems;
-Often overlooked due to being intangible.
Where does noise pollution originate from?
UNDERSTANDING ITS ORIGINS
Noise pollution may come from various sources, such as:
●TRANSPORTATION: Road traffic, airplanes, trains.
●CONSTRUCTION AND INFRASTRUCTURE: Construction sites, roadworks.
●URBANIZATION: residential, commercial, recreational activities.
●COMMERCIAL ACTIVITIES: Restaurants, bars, entertainment venues.
●NATURAL PHENOMENA: Thunderstorms, volcanic eruptions, and wildlife.
