TL;DR: The development of a new noise metric, which has been termed the Noise Gap Index (NGI), is described to incorporate other background environmental noise and to describe and assess the impacts of aircraft noise on the health and well-being of residents.
Abstract: Aircraft noise potentially disturbs (or annoys) the daily activities (such as communication and relaxation) of residents living in the vicinity of airports. This particular type of annoyance undermines quality of life and can be a cause of stress. Evidence is emerging that appears to associate some forms of health risk with this stress. This research aims at developing a better understanding of the impacts of aircraft noise on community health and well-being. This paper presents the results of exploratory data analysis from a pilot survey and a social survey of 704 residents' responses (47% response rate) in Sydney that include people living close to the airport and a matched control group (not affected by aircraft noise). The paper also describes the development of a new noise metric, which has been termed the Noise Gap Index (NGI), to incorporate other background environmental noise and to describe and assess the impacts of aircraft noise on the health and well-being of residents.

TL;DR: In this article, the authors present quantitative relationships which can be used to account for passenger ride quality in transport aircraft and use them to predict passenger comfort and satisfaction under a variety of flight conditions.
Abstract: Quantitative relationships are presented which can be used to account for passenger ride quality in transport aircraft. These relations can be used to predict passenger comfort and satisfaction under a variety of flight conditions. Several applications are detailed, including evaluation of use of spoilers to attenuate trailing vortices, identifying key elements in a complex maneuver which leads to discomfort, determining noise/motion tradeoffs, evaluating changes in wing loading, and others. Variables included in the models presented are motion, noise, temperature, pressure, and seating.

TL;DR: The human auditory system and the perception of sound are discussed in this article, where the major concentration is on the annnoyance response and methods for relating the physical characteristics of sound to those psychosociological attributes associated with human response.
Abstract: The human auditory system and the perception of sound are discussed. The major concentration is on the annnoyance response and methods for relating the physical characteristics of sound to those psychosociological attributes associated with human response. Results selected from the extensive laboratory and field research conducted on human response to aircraft noise over the past several decades are presented along with discussions of the methodology commonly used in conducting that research. Finally, some of the more common criteria, regulations, and recommended practices for the control or limitation of aircraft noise are examined in light of the research findings on human response.

TL;DR: In this article, the main sources of noise are identified and described and described in this chapter Introduction is provided concerning main semi-empirical and computational fluid dynamics methods Noise attenuation methods are also described.
Abstract: High lift devices, together with landing gears, are the main sources of airframe noise during the approach-and-landing phase of aircraft flight Typical high lift devices include leading edge slats and trailing edge flaps Other high-lift-related noise-generating devices include spoilers if deployed during a steep approach operation All the above aerodynamic devices are retracted during the cruise phase of aircraft operation A slat, when deployed, forms a cove region between the slat and the central main element of the aircraft wing Flow separation, flow recirculation, an unsteady shear layer, and slat settings together generate noise of mainly broadband content For a flap, the outboard flap side edge and vortex system associated with it are the main sources of noise The intensity of high lift device noise generally follows a power law of flow velocity The main sources of noise are identified and described in this chapter Introduction is provided concerning main semi-empirical and computational fluid dynamics methods Noise attenuation methods are also described Keywords: acoustics; aircraft noise; airframe noise; high lift devices; slat; flap; acoustic control; flow control
