14 CFR Part 150 sets out the federal rules for airport noise compatibility planning, establishing how airports must measure noise, map affected areas, and develop programs to reduce conflicts between aircraft noise and nearby land uses. It defines key terms such as day-night average sound level (DNL), compatible and noncompatible land use, and noise exposure maps, and it outlines the process by which the FAA reviews and approves or disapproves airport noise compatibility programs. Importantly, FAA approval of such a program does not itself commit federal funding or authorize specific actions without further environmental review.Open full document
Notes
Title 14 of the Code of Federal Regulations, Part 150, governs airport noise compatibility planning for public use airports. It prescribes procedures, standards, and methodology for developing and reviewing noise exposure maps and noise compatibility programs, including definitions of key terms such as day-night average sound level (DNL), compatible and noncompatible land uses, and noise level reduction. The document covers subparts on general provisions, development of noise exposure maps and compatibility programs, and evaluations and determinations of program effects.
