    Environmental noise: compendium of WHO and other UN guidance on health and environment, 2022 update

    ★ 32
    A 2022 World Health Organization report on environmental noise outlines the health risks posed by traffic, aircraft, and leisure noise, including increased risk of heart disease, sleep disturbance, and hearing impairment. The report recommends that aircraft noise levels stay below 45 dB for average exposure and below 40 dB at night to protect public health. It also defines mitigation strategies ranging from reducing noise at the source to behavior change and community education.

    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.
