This 2009 report from the Airport Cooperative Research Program (ACRP) examines how airports across the country manage aircraft noise in communities that fall outside the standard DNL 65 decibel threshold typically used in federal noise policy. Compiled by consultants from Harris Miller Miller & Hanson, Inc., the synthesis documents real-world airport practices for addressing noise concerns in lower-noise areas that are nonetheless affected by flight operations. The findings are intended to help airport operators, planners, and policymakers develop more responsive and comprehensive noise mitigation strategies beyond federally mandated boundaries.Open full document
Notes
This ACRP Synthesis 16 report, sponsored by the Federal Aviation Administration and published by the Transportation Research Board, compiles information on airport noise programs that address areas outside the DNL 65 noise contour. The study, conducted by consultants at Harris Miller Miller & Hanson, Inc., synthesizes airport practice regarding noise mitigation efforts beyond the federally recognized threshold. It is part of the Airport Cooperative Research Program series aimed at providing near-term solutions to common airport operational challenges.
