The Beacon Hill Community Noise Team is a Seattle resident group that documented excessive noise pollution from Sea-Tac and King County airports, as well as road traffic, across 52 neighborhood sites in 2018. Their measurements found that more than half of recorded noise levels exceeded FAA mitigation thresholds, Seattle city ordinances, and EPA public health standards by up to 800%. The group is calling on local, state, and federal officials to take action, citing compounding health and socioeconomic burdens already faced by Beacon Hill's nearly 40,000 residents.

The Burien Airport Committee met on January 15, 2019 to review and update three proposed city resolutions addressing growth and safety, noise pollution, and health impacts related to Seattle-Tacoma International Airport. The committee also discussed a proposed resolution to restructure its own membership by removing the distinction between business and resident members and adding ex-officio seats for representatives from other airport-related groups. Additional agenda items included an update on open applications to fill vacant committee seats.

In January 2019, the City of Burien, Washington considered Resolution No. 407, a measure drafted by the Burien Airport Committee to address noise pollution from nearby Sea-Tac Airport. The resolution highlighted that the airport's rapid growth had caused serious health, environmental, and economic harm to Burien residents, with current FAA noise level standards far exceeding the safer thresholds recommended by the World Health Organization. The Burien Airport Committee recommended adoption of the resolution, which called for updated noise impact assessments and greater consideration of off-site noise effects.

Research published in the Journal of the American College of Cardiology found that environmental noise from traffic, aircraft, and railways is linked to serious cardiovascular health risks, including high blood pressure, heart attack, heart failure, and stroke. Studies in both humans and animals show that aircraft noise — especially at night — triggers stress hormones and harmful oxidative stress in blood vessels, impairing their ability to function properly. These findings suggest that airport noise exposure is not just a quality-of-life issue but a measurable public health concern with direct effects on heart and vascular health.

A Swiss study interviewed 67 patients with obstructive sleep apnea who used CPAP therapy to estimate the monetary value people place on undisturbed sleep. Patients valued a good night's sleep at an average of about 70 Swiss francs per night, and after adjusting for the difference in severity between sleep apnea and traffic noise disturbance, the researchers estimated that noise-free sleep is worth roughly 7 to 24 Swiss francs per person per night. The findings suggest that sleep disrupted by road traffic noise carries a significant monetary cost that should be factored into airport and transportation noise policy decisions.

A study tracking 326 schoolchildren around Munich's old and new airports found that exposure to aircraft noise impaired children's reading and long-term memory, while children who were relieved of noise when the old airport closed showed improvements in those same areas. Researchers tested the children before and after the airports switched operations, carefully matching noise-exposed and non-exposed groups by socioeconomic background. The findings suggest that aircraft noise has measurable, but potentially reversible, effects on key cognitive skills in school-age children.

This 2001 World Watch article by Ed Ayres examines the growing conflict between expanding airports and the cities surrounding them, highlighting the serious health, environmental, and noise impacts on nearby residents. It challenges the conventional mindset of simply building more airport capacity, noting that a 747 takeoff produces as much air pollution in two minutes as 3,000 cars, and that people living near airports face higher rates of illness and psychological harm. The article explores innovative design alternatives, such as inclined runways and energy-recovering landing systems, as more sustainable solutions to meeting rising air travel demand.
