The noise map facilitates the tracking of trends in transportation-related noise for multiple transportation modes.

The data allow viewing the national picture of potential exposure to aviation and highway noise. The data also allow viewing of the potential exposure at the state or county level. The table below demonstates the percent of U.S. population with the potential to be exposed to transportation noise.
