The Federal Aviation Administration (FAA) regulates aircraft noise by specifying the maximum noise level that individual civil aircraft can emit through requiring aircraft to meet certain noise certification standards. These standards designate changes in maximum noise level requirements by "stage" designation. The U.S. noise standards are defined in the Code of Federal Regulations (CFR) Title 14 Part 36 – Noise Standards: Aircraft Type and Airworthiness Certification (14 CFR Part 36).[12] The FAA also pursues a program of aircraft noise control in cooperation with the aviation community.[13] The FAA has set up a process to report aviation-related noise complaints for anyone who may be impacted by Aircraft noise.
