The Quiet Communities Act of 2025 would reestablish the Environmental Protection Agency's Office of Noise Abatement and Control, which has been unfunded since 1982. The office would work to reduce noise pollution from aircraft, traffic, and other sources by providing technical assistance and grants to states and cities, conducting research on noise's health effects, establishing regional assistance centers, and developing educational programs. The bill is aimed at reducing hearing loss, sleep disruption, cardiovascular problems, and workplace productivity losses caused by chronic noise exposure affecting millions of Americans. The legislation authorizes $25 million annually for fiscal years 2026 through 2030 and requires the EPA to complete a study on aircraft noise and its impacts within two years, with recommendations for new mitigation measures.
