This study projects the long-term health and economic costs of aircraft noise generated by the NextGen automated flight system, focusing on communities near Baltimore Washington International Airport. Using a mathematical simulation model, researchers estimated the impact of noise exposure on cardiovascular disease, anxiety, annoyance, and low birth weight over periods of 10, 20, and 30 years. The findings are intended to inform noise mitigation policies and provide a clearer picture of the public health consequences of modern air traffic management systems.

Aviation noise consultant Vince Mestre explains to the Port of Seattle why changing the FAA's 65 DNL noise contour standard — the threshold used to determine acceptable aircraft noise near residential areas — would likely require an act of Congress rather than a simple regulatory update. The 65 DNL standard is embedded in at least three federal regulations and orders (CFR 14 Parts 150 and 161, and FAA Order 1050.1F), all of which trace their authority back to enabling legislation such as the Aviation Safety and Noise Abatement Act (ASNA) of 1978 and the Airport Noise and Capacity Act (ANCA) of 1990. Because the FAA's rulemaking authority is granted and bounded by those Congressional statutes, modifying ASNA would most likely be required before the FAA could formally lower or otherwise change the noise compatibility standard.

A large study of over 35,000 female nurses across the United States found that exposure to aircraft nighttime noise levels at or above 45 decibels was associated with 23% greater odds of sleeping less than 7 hours per night. The research, which tracked participants living near 90 U.S. airports between 2000 and 2014, suggests that aircraft noise — including at levels below the federally regulated threshold of 65 decibels — may meaningfully disrupt sleep duration. Stronger effects were observed among residents in the Western United States and those living near major cargo airports, findings with direct relevance to communities around airports like Sea-Tac.

Academic paper presented at the 183rd Meeting of the Acoustical Society of America arguing that the FAA’s 65 dBA day-night average sound level standard is not safe for public health. The paper discusses how the EPA calculated safer levels at 55 dB for outdoor activities and 45 dB for indoor activities, and examines the non-auditory

This article from the Snohomish County Business Journal discusses growing interest in establishing scheduled commercial air service at Paine Field in Everett, Washington, as an alternative to the congested Sea-Tac Airport. Supporters argue that commercial flights would boost the local economy and attract new businesses, while noting that modern, quieter aircraft have significantly reduced noise concerns. The county's 20-year airport master plan, approved in December, projected commuter service flights from Paine Field within five years.
