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.
The takeoff procedure at John Wayne Airport is unique because of the local noise restrictions and short runway. [51] When using the typical traffic pattern (departures from runway 20R) most commercial airliners cycle to full power (95–97%) while holding at the end of the runway then release the brakes when engines are fully spooled up.
SID procedures are defined by local authorities (governments, airports, and air traffic control organizations) to ensure safety and expedite handling of departing traffic and, when possible, to minimize the amount of noise over inhabited areas such as cities.
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.

Modern aircraft equipped with mid and high-bypass turbofan engines are designed to comply with contemporary aviation noise abatement laws and ICAO regulations. Several older aircraft that are still in service (typically in a cargo capacity) have hush kits retrofitted so that they are able to conform with noise regulations needed to operate in ...
The FAA also pursues a program of aircraft noise control in cooperation with the aviation community. [112] The FAA has set up a process to report for anyone who may be impacted by aircraft noise. [113] The Federal Highway Administration (FHWA) developed noise regulations to control highway noise as required by the Federal-Aid Highway Act of ...
