This presentation by attorney Peter J. Kirsch, delivered at the 2021 Aviation Noise and Emissions Symposium, examines anticipated legislative priorities related to aircraft noise and emissions in the new Congress. It references key noise measurement tools, including the Schultz Curve and a updated National Curve, both of which plot the percentage of people highly annoyed against Day-Night Average Sound Level (DNL) in decibels. The materials suggest growing public sensitivity to aircraft noise even at lower decibel levels, with implications for how policymakers may revisit the longstanding 65 DNL threshold used in federal noise compatibility programs.Open full document
