    Sea-Tac ground noise study: Highline Forum

    This document presents findings from a Sea-Tac Airport Ground Noise Study, shared at the Highline Forum on November 20, 2019. It explains how aircraft ground noise travels and changes with distance, noting that sound levels drop by 6 dB every time the distance doubles and are further reduced by atmospheric absorption and soft ground surfaces. The study also covers how temperature gradients affect noise, with sound bending upward in normal conditions and downward during temperature inversions, potentially increasing noise impacts on nearby communities.

    Sound mitigation briefing: Highline Forum

    This July 2019 briefing presented to the Highline Forum outlines Sea-Tac Airport's sound mitigation efforts under the FAA's Part 150 program, a voluntary federal framework that helps airports address noise and land use conflicts while qualifying for up to 80% federal grant funding. Sea-Tac's program, which began in 1985 and has undergone three updates (most recently in 2014), has involved extensive public outreach including workshops, city council presentations, and community forums.
