NOTES: Noise-level contours are
graphical representations of noise levels on a map, similar to elevation
contours on a topgraphic map.
Noise-level contours are lines that join points of equal sound levels.
Areas between given noise-level contour lines would have a noise level
between the two contour values. The
U.S. Department of Transportation, Federal Aviation Administration (FAA) has
identified DNL 65 dB as the highest threshold of airport noise exposure that
is normally compatible with indoor and outdoor activity associated with a
variety of land uses, including residential, recreational, schools, and
hospitals.
Estimates are for areas surrounding airport property of 250 of the
largest civil airports with jet operations in the United States. They exclude exposure to aircraft noise
within an airport boundary.
