TagNoise Mitigation(208)

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.

Annual progress report documenting the implementation of the LAX Master Plan Community Benefits Agreement for 2008. The report covers various community benefit programs including residential noise mitigation, job training, first source hiring, living wage requirements, air quality studies, health studies, and minority business enterprise programs.

This document is the FAR Part 150 Noise Compatibility Program Study Update for Seattle-Tacoma International Airport (Sea-Tac), approved by the FAA in June 2002. It outlines a series of measures aimed at reducing aircraft noise, including establishing a public oversight committee, exploring noise barriers and ground run-up enclosures, and encouraging the voluntary phase-out of older, louder Stage 2 jet aircraft. The FAA approved some measures outright, while others—such as revised maintenance run-up regulations and the voluntary aircraft phase-out—were disapproved pending submission of additional supporting information.
