TL;DR: In this article, the authors focus on the human factors implications resulting from the introduction of Continuous Descent Approach (CDA) noise abatement procedures at airports, and report on results from experiments examining the cognitive implications of changing speed profiles during the approach.
Abstract: This paper focuses on the human factors implications resulting from the introduction of Continuous Descent Approach (CDA) noise abatement procedures at airports. CDA procedures are effective in keeping aircraft higher and at lower thrust levels for a longer period of time in comparison to conventional techniques, thus reducing aircraft noise in the vicinity of airports. However, the use of CDAs can lead to changes in aircraft behavior during approach operations, and this can then affect how they are managed by air traffic controllers. The paper reports on results from experiments examining the cognitive implications of changing speed profiles during the approach. It presents recommendations regarding the standardization of deceleration profiles in CDA procedures, leading also to a reduction in workload for air traffic controllers.

TL;DR: A reliably lower prevalence rate of annoyance (but not of complaints) with rattle and vibration was noted among respondents living in homes that had been treated to achieve a 5-dB improvement in A-weighted noise reduction than among respondentsliving in untreated homes.
Abstract: A near-replication of a study of the annoyance of rattle and vibration attributable to aircraft noise [Fidell et al., J. Acoust. Soc. Am. 106, 1408–1415 (1999)] was conducted in the vicinity of Minneapolis-St. Paul International Airport (MSP). The findings of the current study were similar to those reported earlier with respect to the types of objects cited as sources of rattle in homes, frequencies of notice of rattle, and the prevalence of annoyance due to aircraft noise-induced rattle. A reliably lower prevalence rate of annoyance (but not of complaints) with rattle and vibration was noted among respondents living in homes that had been treated to achieve a 5-dB improvement in A-weighted noise reduction than among respondents living in untreated homes. This difference is not due to any substantive increase in low-frequency noise reduction of acoustically treated homes, but may be associated with installation of nonrattling windows. Common interpretations of the prevalence of a consequential degree of annoyance attributable to low-frequency aircraft noise may be developed from the combined results of the present and prior studies.

TL;DR: The aircraft noise problem is reviewed and a description and assessment of a number of sound propagation methods suitable for applications with a background mean flow field pertinent to aircraft noise are described and assessed.
Abstract: Noise generated by civil transport aircraft during take-off and approach-to-land phases of operation is an environmental problem. The aircraft noise problem is firstly reviewed in this article. The review is followed by a description and assessment of a number of sound propagation methods suitable for applications with a background mean flow field pertinent to aircraft noise. Of the three main areas of the noise problem, i.e. generation, propagation, and radiation, propagation provides a vital link between near-field noise generation and far-field radiation. Its accurate assessment ensures the overall validity of a prediction model. Of the various classes of propagation equations, linearised Euler equations are often casted in either time domain or frequency domain. The equations are often solved numerically by computational aeroacoustics techniques, bur are subject to the onset of Kelvin-Helmholtz (K-H) instability modes which may ruin the solutions. Other forms of linearised equations, e.g. acoustic perturbation equations have been proposed, with differing degrees of success.

TL;DR: In this paper, the authors used particle image velocimetry (PIV) and fluctuating surface pressure data acquired using flush mounted pressure transducers near the surface trailing edge.
Abstract: Modern aircraft design often puts the engine exhaust in close proximity to the airframe surfaces. Aircraft noise prediction tools must continue to develop in order to meet the challenges these aircraft present. The Jet-Surface Interaction Tests have been conducted to provide a comprehensive quality set of experimental data suitable for development and validation of these exhaust noise prediction methods. Flow measurements have been acquired using streamwise and cross-stream particle image velocimetry (PIV) and fluctuating surface pressure data acquired using flush mounted pressure transducers near the surface trailing edge. These data combined with previously reported far-field and phased array noise measurements represent the first step toward the experimental data base. These flow data are particularly applicable to development of noise prediction methods which rely on computational fluid dynamics to uncover the flow physics. A representative sample of the large flow data set acquired is presented here to show how a surface near a jet affects the turbulent kinetic energy in the plume, the spatial relationship between the jet plume and surface needed to generate surface trailing-edge noise, and differences between heated and unheated jet flows with respect to surfaces.

TL;DR: Consideration of noise metrics related to the number of fly-overs and individual adjustment of noise metric can improve the prediction of short-term annoyance compared to models using equivalent outdoor levels only.
