National Transportation Noise Map

  • The multi-modal National Transportation Noise Map facilitates the tracking of trends in transportation-related noise produced by both individual modes – whether aviation, highway, or passenger rail – and collectively across all three modes.
  • The decibel values shown on the Noise Map are estimates of the average quantity of noise energy emitted by one or more modes of transportation at each location during a given 24-hour period.
  • The noise data visualized on the map should be used for the purpose of tracking trends, not for assessing impact.
  • 2020 data will be released this spring.
