Seattle-Tacoma International Airport operates a permanent noise monitoring system consisting of 24 monitors placed in surrounding communities and along flight paths north and south of the airport's three runways. Upgraded in 2015 with Larson Davis 831 equipment, the system continuously captures aircraft noise event data for both departures and arrivals. This data is compiled monthly and made publicly available through the Port of Seattle's Noise Programs website.

A presentation given at the StART Meeting on October 28, 2020, providing an overview of the Seattle-Tacoma International Airport noise monitoring system. The system consists of 24 permanent monitors located in close-in communities surrounding SEA, upgraded in 2015 with Larson Davis 831 equipment. Aircraft noise event data is gathered and shared monthly via the Port’s Noise Programs website.

Sidebar On/Off

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
