Noise-generating aircraft propeller. Aircraft noise is noise pollution produced by an aircraft or its components, whether on the ground while parked such as auxiliary power units, while taxiing, on run-up from propeller and jet exhaust, during takeoff, underneath and lateral to departure and arrival paths, over-flying while en route, or during landing.
Detailed information on measurement of aircraft acoustic signature to meet the requirements of Annex 16 is found in ICAO Document 9501 [6] and IEC 61265. [7] Data acquisition in one-third-octave bands is required, followed by processing to yield a logarithmically-scaled value in decibels relative to a sound pressure of 20 micropascals for each one-third-octave band.
The International Aviation Safety Assessment Program (IASA Program) is a program established by the U.S. Federal Aviation Administration (FAA) in 1992. The program is designed to evaluate the ability of a country's civil aviation authority or other regulatory body to adhere to international aviation safety standards and recommended practices for personnel licensing, aircraft operations and ...
The FAA became more involved with the environmental aspects of aviation in 1968 when it received the power to set aircraft noise standards. Legislation in 1970 gave the agency management of a new airport aid program and certain added responsibilities for airport safety.
The ICAO Chapter 14 noise standard applies for aeroplanes submitted for certification after 31 December 2017, and after 31 December 2020 for aircraft below 55 t (121,000 lb), 7 EPNdB (cumulative) quieter than Chapter4. [48] The FAA Stage 5 noise standards are equivalent. [49] Higher bypass ratio engines produce less noise.
In United States and Canadian aviation, the Aeronautical Information Manual (AIM) [1] (formerly the Airman's Information Manual) is the respective nation's official guide to basic flight information and air traffic control procedures. These manuals contains the fundamentals required in order to fly legally in the country of origin.
Standards And Recommended Practices (SARPs) are technical specifications adopted by the Council of ICAO in accordance with Article 37 of the Convention on International Civil Aviation in order to achieve "the highest practicable degree of uniformity in regulations, standards, procedures and organization in relation to aircraft, personnel, airways and auxiliary services in all matters in which ...
Industrial noise control is a subset of interior architectural control of noise, with emphasis on specific methods of sound isolation from industrial machinery and for protection of workers at their task stations. Sound masking is the active addition of noise to reduce the annoyance of certain sounds, the opposite of soundproofing.
