    Compilation of noise programs in areas outside DNL 65

    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.

  • Forecasted Noise Contour Map 1980, 1985,1990, 2000

    Exhibit 1-1 from the Port of Seattle's Sea-Tac International Airport Noise Exposure Update, showing four panels of DNL (Ldn) noise contour maps at the 65, 70, and 75 dB levels for the years 1980, 1985, 1990, and 2000. The contours illustrate the projected lateral and longitudinal extent of aircraft noise impact around the airport's runway alignment over those two decades.
