The Highline Forum held its July 22, 2020 meeting virtually via Microsoft Teams, hosted by the City of Federal Way, focusing on ultra-fine particle studies, noise program updates, and StART (Sea-Tac Airport Roundtable) developments near Seattle-Tacoma International Airport. Key presentations included University of Washington air quality research (MOV-UP study), a temporary noise monitors update from the Port of Seattle, and a South King County Fund update. The meeting was conducted remotely due to the Governor's Stay-at-Home Order, with public comments accepted via email or MS Teams.

The Burien Airport Committee held a virtual meeting on July 21, 2020, to discuss several airport-related issues affecting the community, including flight patterns, noise monitoring, and re-engagement with the SeaTac Airport Roundtable (StART). Key agenda items included a potential request for a temporary portable noise monitor in Burien, recommending representatives for NextGen/PBN rollout discussions with the GAO, and continuing discussions on inviting Port Commissioners to meet with the committee and City Council. Draft minutes from the June 16, 2020 meeting also reflected earlier discussions about airport impact mitigation, equity concerns, and a proposed letter to the Port Commission addressing a post-COVID 'new normal' for airport operations.

In a July 17, 2020 email to Burien Airport Committee members, Sharyn Parker urges the City of Burien to accept Sea-Tac Airport's offer to place a temporary portable noise monitor in the city, noting there is currently no monitor near the 'New Route' where Q400 turboprop and jet aircraft continue to fly westbound during north-flow conditions. Parker cautions that site selection is a complex process requiring careful attention to obstacles, noise buffers, and power availability, drawing on her experience with King County International Airport where similar projects took two to four years. She recommends the city respond with a simple 'yes' by the July 24, 2020 deadline and request an extension if needed to properly identify one or two suitable monitoring locations.

In October 2019, community advocate Sharyn Parker responded to a request for public input on a Sea-Tac Airport airfield ground noise study being conducted by consulting firm HMMH. Parker argued that the consultant should first analyze existing noise monitor station data, correlate it with engine run-up records and resident complaints, and review compliance with Washington State noise regulations (WAC 173-60) before seeking community feedback. She also raised concerns about non-functioning noise monitors, the airport's unverified claims about off-site engine testing, and potential overlap with a separate noise study tied to the airport's master planning process.

These emails, dated October–November 2019, relate to a study of ground-level noise at Seattle-Tacoma International Airport initiated by the StART Aviation Noise Working Group. Noise consultant Brad Nicholas of HMMH sought input from surrounding cities, including Burien (which had suspended its StART membership), on which noise sources to analyze and where to place monitoring equipment. Community advocate Sharyn Parker responded with detailed recommendations, arguing the consultant should first correlate existing noise complaints and monitor records with engine run-up events before soliciting public input, and identifying engine run-ups and reverse thrust as the two primary sources of airfield ground noise.

This report summarizes annual trends on issues regarding noise exposure from the City of Phoenix’s three airports, Phoenix Sky Harbor International (PHX), Phoenix Deer Valley (DVT), andPhoenix Goodyear (GYR) for calendar year 2018. The report includes information on operational counts, aircraft fleet mix, noise complaints, runway usage, noise abatement procedures, noise monitoring, and general aviation

The Port of Seattle issued Purchase Order A-0000274251 to Exelis Inc. of Herndon, VA, for a Noise Monitoring and Flight Tracking System at Seattle-Tacoma International Airport, originally dated January 21, 2015. Two change orders were subsequently issued: Change Order 1 reduced the contract price by $18,400 (replacing four weather stations with METARS data), and Change Order 2 increased it by $32,802 for additional site modifications, bringing the final total PO amount to $1,001,655.16.

The Larson Davis Model 831 Technical Reference Manual provides comprehensive guidance for operating a handheld precision sound level meter and real-time frequency analyzer. The manual covers 27 chapters and 4 appendices addressing topics such as measurement setup, noise dose and exposure monitoring, time history logging, calibration, and data storage. It serves as a complete reference for professionals conducting acoustic measurements, including those relevant to environmental noise monitoring near airports.
