9th Propulsion Conference, 1973
Opportunities to reduce military aircraft noise without inhibiting mission capability are considered. Emphasis is placed on the need for a comprehensive military aircraft noise abatement program involving compatible land use in the vicinity of military airports, operational constraints, and procedures to reduce noise impact and source noise reduction ...

Masking of Speech by Aircraft Noise
The Journal of the Acoustical Society of America, 1966Word-intelligibility tests at various intensity levels were administered to a crew of trained listeners in the presence of recorded noise from jet and propeller-driven aircraft. The noise was that which would be present outdoors and in a house as the result of engine runup operations and if aircraft were flying overhead shortly after takeoff and prior ...

Aircraft noise and psychiatric morbidity
Psychological Medicine, 1973SynopsisAn earlier investigation which showed that admission rates to a psychiatric hospital were higher from the higher noise zones close to Heathrow Airport than from relatively quieter areas was repeated. The present paper could not confirm those results, although a trend in agreement with the original findings was found.

AIRCRAFT APPROACH NOISE TRIALS
Inter-Noise 2022, 2023This article presents the results from a series of aircraft approach trials that were conducted with the aim to investigate noise reduction procedures within the boundaries of a normal ILS approach. The significant decline in air traffic at Stockholm Arlanda, that occurred during the pandemic meant that the empty airspace and the availability of ...

Aircraft Noise and Incidence of Hypertension
Epidemiology, 2007An association between aircraft noise exposure and hypertension prevalence has been suggested but there are no longitudinal studies of this association. Our aim was to investigate the influence of aircraft noise on the incidence of hypertension.A cohort of 2754 men in 4 municipalities around Stockholm Arlanda airport was followed between 1992-1994 and ...

Noise & Vibration Worldwide, 2003
Various noise measurement parameters/indices used to define aircraft and airport noise are explained. The noise zone limits used around airports in some countries are given. Noise prediction software can be used to generate noise contours around airports.

Aircraft noise and birth weight
International Archives of Occupational and Environmental Health, 1981Data from six infant welfare centres in the vicinity of Amsterdam airport were analysed. Birth weights of 902 infants were related to aircraft noise levels to which the mother was exposed in pregnancy. The analysis was restricted to deliveries in hospital, single births and mothers aged 20–34 years.

Scaling aircraft noise perception
Journal of Sound and Vibration, 1971An experiment was undertaken to evaluate various methods for calculating the perceived level of aircraft flyover sound. One hundred and twenty recorded sounds of jets, turboprops, piston engined aircraft, and helicopters were compared in a paired comparison test.

Evaluation Criteria for Aircraft Noise
Reviews on Environmental Health, 2003Based on extensive and detailed reviews the present paper suggests evaluation limits for aircraft noise for the prediction of noise effects and for the protection of residents living in the vicinity of (newly constructed or extended) civil airports.

Aerodynamic Noise and the Estimation of Noise in Aircraft
The Journal of the Acoustical Society of America, 1952Noise resulting from the flow of air over the fuselage of an airplane has been investigated and found to depend principally on approximately the fifth power of the indicated air speed. The resulting emperical relation of noise level to airspeed is found to be quite useful in estimating the noise in the frequency range above 600 cps, for airplanes ...
