More technically, the sound from the airflow and aircraft engines that passengers hear inside the cabin is pink noise, white noise's low–pitch cousin. Like a deep, continuous exhale, its ambient acoustics can actually have a calming effect..
When did airport noise become an environmental issue?
Mitigation programs. In the United States, since aviation noise became a public issue in the late 1960s, governments have enacted legislative controls. Aircraft designers, manufacturers, and operators have developed quieter aircraft and better operating procedures..
When did planes get quiet?
In 1990, federal law required large jet airplanes to comply with stage 3 noise standards by 1999, leading to a phase-out of the noisiest airplanes (stage 1 and 2 airplanes). Later, federal law required smaller airplanes to comply with stage 3 standards by 2016..
Where does aircraft noise come from?
A moving aircraft causes friction and turbulence, which triggers sound waves. Generally, the faster the aircraft is flying, the more turbulence and friction will occur. When the aircraft's landing gear and flaps are used, more noise is made because more resistance is being created..
Who is responsible for aircraft noise?
Who regulates the airspace, aircraft activity and noise? In the United States, the Federal Aviation Administration (FAA) regulates airspace, aircraft, pilots, airports, flight procedures and aircraft noise..
There are many sources of noise pollution, but here are some of the main ones:
Traffic noise.Air traffic noise.Construction sites.Catering and night life.Animals.
A study of noise on Airbus A321 aircraft reported levels of 60-65 decibels (dBA) before takeoff; 80-85 dBA during flight; and 75-80 dBA during landing. The outside of aircraft engines (around 140 dB at takeoff) and conditions on other aircraft may have higher or lower noise levels.
Aircraft noise at high levels can be considered a stressor on the body, and research has found an association between high levels of aircraft noise and an increased risk of developing Cardiovascular disease (CVD).
Any aircraft that is not exempt under the Air Navigation (Aircraft Noise) Regulations 2018, is required to carry a noise certificate on board the aircraft at all times (under Section 11 of the Regulations) – either in the form of an Australian Noise Certificate or evidence that this aircraft is Deemed, through
Government and the aviation industry have worked to try and reduce the impact of noise by promoting the use of quieter aircraft, restricting the times airports can operate and the routes that can be used and, in some cases, capping the total number of flights that can depart from and arrive into an airport.
ICAO BALANCED APPROACH The four elements of the Balanced Approach are: reduction of noise at source; effective land-use planning and management; noise abatement operational procedures; and operating restrictions.
In the present study, six noise reduction strategies including the optimization of aircraft type, regulation of number of night flights, flight procedure, modification of operating runway, land use planning and the installation of sound insulation windows were proposed to reduce the impacts of aircraft noise on the
Jet engines produce noise in different ways, but mainly it comes from the high-speed exhaust stream that leaves the nozzle at the rear of the engine. And planes are loudest when they move slowly, such as at takeoff or at landing.
Elevated noise levels can create stress, increase workplace accident rates, and stimulate aggression and other anti-social behaviors. Airport noise has been linked to high blood pressure. Aircraft noise increases risks of heart attacks.
Aircraft noise is a public health issue. It can impact memory and learning in children, disturb sleep, and cause serious long-term health problems including cardiovascular disease.

Aviation noise pollution
Environmental noise is an accumulation of noise pollution that occurs outside. This noise can be caused by transport, industrial, and recreational activities.
Helicopter noise reduction is a topic of research
Reducing the noise caused by helicopters
Helicopter noise reduction is a topic of research into designing helicopters which can be operated more quietly, reducing the public-relations problems with night-flying or expanding an airport. In addition, it is useful for military applications in which stealth is required: long-range propagation of helicopter noise can alert an enemy to an incoming helicopter in time to re-orient defenses.
1972 American legislation
The Noise Pollution and Abatement Act of 1972 is a statute of the United States initiating a federal program of regulating noise pollution with the intent of protecting human health and minimizing annoyance of noise to the general public.
Noise Free America is a national, non-profit organization aimed at reducing noise pollution in the community. The organization's main target is noise from boom cars, leaf blowers, motorcycles, and car alarms. Noise Free America has a 501(c)(3) non-profit status and has chapters in 27 states across the U.S. Its headquarters are located in Chapel Hill, North Carolina.
In acoustics, noise measurement can be for the purpose of measuring environmental noise or measuring noise in the workplace. Applications include monitoring of construction sites, aircraft noise, road traffic noise, entertainment venues and neighborhood noise. One of the definitions of noise covers all unwanted sounds. When sound levels reach a high enough intensity, the sound, whether it is wanted or unwanted, may be damaging to hearing. Environmental noise monitoring is the measurement of noise in an outdoor environment caused by transport, industry and recreational activities. The laws and limits governing environmental noise monitoring differ from country to country.
Noise pollution
Excessive, displeasing human, animal, or machine-created environmental noise
Noise pollution, or sound pollution, is the propagation of noise or sound with ranging impacts on the activity of human or animal life, most of which are harmful to a degree. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems. Poor urban planning may give rise to noise disintegration or pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas. Some of the main sources of noise in residential areas include loud music, transportation, lawn care maintenance, construction, electrical generators, wind turbines, explosions and people.
