2010 Noise Contour vs. 1999 Noise Contour
This map compares the 65 DNL of the Existing 2009 Baseline noise exposure contour (black line) to the 1999 Recommended noise exposure contour (green line) that was prepared for the Lambert 1995 Part 150 Noise Compatibility Study. This comparison illustrates that the noise levels at Lambert have decreased significantly since the late 1990s. For factors leading to a reduction in aircraft noise at Lambert click here.
