Which of the following are common sources of noise pollution?

• A. Weather patterns
• B. Ocean salinity
• C. Solar radiation
• D. Transportation, construction, domestic and industrial activity

Answer: (D)

Noise pollution comes from human activities that generate loud, disruptive sounds in everyday environments. Transportation, construction, and industrial and domestic activities produce the most common and persistent noises—cars, trucks, trains, planes, bulldozers, drills, factory equipment, and loud household tools and appliances—across urban and industrial areas. These sources create high-volume or ongoing noise that can disturb sleep, concentration, and health, which is why they’re identified as the main contributors. Natural sounds from weather or the sea can be loud at times, but they aren’t the everyday sources of noise pollution in communities, and ocean salinity or solar radiation don’t create noise.
