    Federal airport noise regulations and programs

    This Congressional Research Service report explains how the federal government regulates aircraft noise around U.S. airports, primarily through two FAA programs: a voluntary noise compatibility planning program (Part 150) and a framework governing noise-based access restrictions (Part 161). It also highlights a key policy debate around whether the longstanding DNL 65 decibel threshold for 'significant' noise is still appropriate, given newer FAA survey data suggesting communities are significantly annoyed at much lower noise levels. The report is relevant to ongoing discussions about updating federal aviation noise standards ahead of the expected 2023 FAA reauthorization.

    Analysis of the Neighborhood Environmental Survey

    This 2021 FAA report analyzes the Neighborhood Environmental Survey (NES), a large-scale study examining how aircraft noise affects communities around 20 U.S. commercial airports. Researchers surveyed over 10,000 residents and found that annoyance with aircraft noise increases steadily as noise levels rise, with significantly more people reporting high annoyance than older studies had suggested. The findings provide an updated national curve showing the relationship between measured noise exposure (DNL) and community annoyance, which can inform airport noise policy decisions.
