A federal court ruled in 2023 that the EPA had unreasonably delayed for over 40 years in carrying out its legal duties under the Noise Control Act of 1972, which requires the agency to regulate environmental noise, publish noise-related reports, and help state and local governments develop noise control programs. Although President Reagan defunded the EPA's noise office in 1982, Congress never actually repealed the Noise Control Act, meaning the EPA's obligations under the law remained in force. The court granted partial summary judgment in favor of the plaintiffs, finding the EPA's inaction on four key counts unlawful.

A document explaining changes to aircraft arrival patterns at SeaTac airport around 2015, including the introduction of Performance Based Navigation (PBN) technology and lowered flight altitudes. The changes concentrated flight paths over Vashon Island in a narrow corridor, causing increased noise pollution for residents who chose to live there for its peaceful environment.

A letter from the City of Burien to WSDOT criticizes the 2017 Washington Aviation System Plan (WASP) for failing to address the health and environmental impacts of growing aircraft noise and air pollution on communities near Seattle-Tacoma International Airport. The letter argues that the plan focuses too narrowly on aviation and economic development while ignoring issues such as hearing loss, poor student performance, sleep disruption, and asthma affecting lower-income and ethnically diverse neighborhoods. The author calls on WSDOT and regional governments to explore alternative airport locations to relieve the disproportionate burden placed on South King County communities.

A 2024 study published in the Journal of Exposure Science & Environmental Epidemiology assessed the public health impacts of military aircraft noise from Naval Air Station Whidbey Island in Washington State, finding that over 74,000 residents were at risk of adverse health effects including annoyance, sleep disturbance, hearing impairment, and delays in childhood learning. Researchers integrated seven years of acoustic monitoring data with flight operations records and noise simulation models to map noise exposure across six counties in northwestern Washington. The study's findings and open-source workflow offer a reproducible tool for evaluating population health risks from aviation noise, with broader applications for informing noise policy, land use planning, and mitigation efforts.

Burien resident and former Boeing Field Noise Officer Sharyn Parker testified in support of HB 1683, arguing that the Port of Seattle deliberately understated Sea-Tac Airport's growth projections to avoid alarming nearby communities, while simultaneously planning a multi-billion dollar expansion — leaving residents exposed to increasing noise and emissions without adequate mitigation. She points to the Port's 2013-2018 Part 150 Noise Study becoming outdated just two years after approval, and a four-year delay in implementing approved sound insulation measures, as evidence of mismanagement and misleading communications. Parker and coalition members are calling for nighttime cargo flights to be offloaded to a new regional airport, contending that Sea-Tac has exhausted both its physical footprint and airspace capacity.

The FAA's Noise Policy Review examines the growing problem of aircraft noise around airports, comparing historical and current annoyance levels among nearby residents. A Neighborhood Environmental Survey found a substantial increase in the percentage of people highly annoyed by aircraft noise, with annoyance rising consistently across all levels of noise exposure — well above what older models like the Schultz Curve had predicted.

H.R. 4178, the Quiet Communities Act of 2023, is a bill introduced in the U.S. House of Representatives on June 15, 2023, that seeks to reestablish the EPA's Office of Noise Abatement and Control, which has received no funding since 1982. The bill highlights the serious health impacts of noise pollution — including hearing loss, cardiovascular disorders, sleep deprivation, and learning deficits in children — affecting millions of Americans exposed to noise from aircraft, vehicular traffic, and other sources. Because the EPA remains legally responsible for enforcing noise regulations while lacking an active office to do so, and because federal law limits state and local governments from regulating many noise sources, the bill argues that noise abatement programs across the country have effectively lain dormant.
