TL;DR: In this article, a series of flyover noise tests on the Airbus A319 performed in the framework of the German project "Noise Optimized Approach and Departure Procedures (LAnAb)" took place at Parchim airport (Germany) in June 2004.
Abstract: A series of flyover noise tests on the Airbus A319 performed in the framework of the German project ”Noise Optimized Approach and Departure Procedures (LAnAb)” took place at Parchim airport (Germany) in June 2004. A noise database was created that will be a support for the validation of aircraft noise prediction models dedicated to investigate noise abatement procedures. In all, 37 take-off and 82 approach conditions were simulated. Depending on the simulated flight phase, different values of engine power, airspeed, position of the high-lift devices, and also of the landing gears were tested. The aim of this paper is to show the different possibilities of using the signals recorded by a phased-array of microphones installed on the ground to analyse aircraft noise and confront some prediction models to the results.

TL;DR: Today’s aircraft noise calculation programs either use simple sound source descriptions with few input parameters or highly sophisticated models with input parameters, which are difficult to obtain.

16 Oct 2001TL;DR: The factors that limit the ability of air traffic controllers to separate aircraft without automation aids are discussed, and an automation infrastructure that utilizes flight operation uncertainties observed from an experimental pilot-inthe-loop simulation study is offered to predict the initial separations necessary for aircraft to maintain the required minimum separation throughout the approach.
Abstract: have been adopted and implemented. These measures include directing aircraft over unpopulated areas, phasing out noisier aircraft, enforcing nighttime curfews on the operation of certain aircraft, publicizing airlines noise mitigation efforts, and utilizing advanced engine technology to reduce source noise. While these measures have contained the impact of aircraft noise, the increased demand for air transportation has not been matched by increased capacity, thus resulting in greater delays and congestion at major airports during this past decade. Advanced approach noise abatement procedures enabled by flight guidance technologies such as GPS and FMS have been shown to reduce the impact of noise in communities near airports. The implementation of these procedures, however, is hindered by the inability of air traffic controllers to separate aircraft that are decelerating at significantly different rates. This is especially problematic when the traffic density is high or when atmospheric conditions are turbulent. This paper discusses the factors that limit the ability of air traffic controllers to separate aircraft without automation aids, and offers an automation infrastructure that utilizes flight operation uncertainties observed from an experimental pilot-inthe-loop simulation study to predict the initial separations necessary for aircraft to maintain the required minimum separation throughout the approach.

TL;DR: In this article, the effects of aircraft noise at night were discussed in relation to the influence of subjective factors such as attitude, stress, and attitude, and it was suggested that anxiety that night noise significantly reduces the benefits derived from sleep may be just as harmful, through stress, as any actual loss of sleep.
Abstract: This report provides details of ongoing research in the UK on the effects of aircraft noise at night. Whether exposure adversely affects health is discussed in relation to the influence of subjective factors such as attitude. A disparity between subjective perceptions of noise-induced disturbance and objectively measured disturbance is noted. It is suggested that anxiety that night noise significantly reduces the benefits derived from sleep may be just as harmful, through stress, as any actual loss of sleep. High levels of aircraft noise may wake people but at current levels of exposure near airports, aircraft noise is only one of several causes of sleep disturbance. Current gaps in knowledge are identified.

TL;DR: The state of the art for understanding, predicting, and control of airframe noise, levels and spectral content of the noise, correlation with important variables, and noise generation mechansims are discussed.
Abstract: Progress in quieting the commercial aviation fleet has been achieved by reducing the noise generated by jet engines. Recent tests have indicated that noise produced by airflow over aircraft surfaces (lifting surfaces, landing gear, flaps, and cavities) is only 8 to 10 EPNdB below certification requirements for current aircraft and will likely be a design consideration for aircraft of the future as engines become still quieter. This paper reviews the state of the art for understanding, predicting, and control of airframe noise. Levels and spectral content of the noise, correlation with important variables, and noise generation mechansims are discussed. The noise floors for future aircraft, the direction of research projects, and likely impact of this new technology on aircraft design are indicated.
