Notes

  • The quietness score considers multiple factors including traffic, commercial activity, industrial presence, and environmental noise
  • Results are cached for nearby locations to improve response times
  • The “Top 5 sources of noise” identifies the main contributors to noise at the location, with their distance in miles
  • Coordinates should be in decimal degrees format
