Abstract

While the volume of air traffic continues to rise, there are concurrent shifts in aircraft fleets and advancements in technology aimed at enhancing aircraft efficiency, sustainability, and minimizing noise footprints. These simultaneous developments contribute to the complexity of forecasting airport noise associated with future air traffic. This study presents various scenarios of technology adoption for the years 2030 and 2040 at a European airport, namely Dublin Airport, encompassing changes in fleet distribution. Aircraft are classified into different generations to reflect their technological advancements. Projections indicate an anticipated growth in the wide body fleet at Dublin Airport from 2023 to 2040, while the shares of narrow body, regional jet, and turboprop fleets are expected to decline. Each forecast year showcases three distinct technology uptake scenarios, with noise contour lines at $L_{d e n}$ =

(A) and

L_{n i g h t}

(A) being compared. To assess the impact of these changes on airport noise, the study evaluates alterations in area and population exposure. In general, the findings suggest a trend of increasing population exposure coinciding with the rise in air traffic. Nevertheless, the increase of wide body aircraft at Dublin Airport further increases the noise impact in 2030. Anticipated growth sees new generation 2 aircraft reaching up to

by 2040, leading to a reduction in 2040 noise contour lines compared to 2030—though not returning to the levels observed in 2023.

预测到 2040 年的机场噪声影响：交通流量增长和技术采用情况

在航空交通量持续上升的同时，飞机机队也在发生变化，技术也在不断进步，目的是提高飞机的效率和可持续性，并最大限度地减少噪声足迹。这些同时发生的变化增加了预测未来航空交通相关机场噪声的复杂性。本研究提出了 2030 年和 2040 年欧洲机场（即都柏林机场）采用技术的各种情景，包括机队分布的变化。飞机被分为不同的世代，以反映其技术进步。预测显示，2023 年至 2040 年，都柏林机场的宽体机机队预计将增长，而窄体机、支线喷气机和涡轮螺旋桨机队的份额预计将下降。每个预测年都会出现三种不同的技术吸收情况，并对 Lden = (A) 和 Lnight = (A) 时的噪声等值线进行比较。为了评估这些变化对机场噪声的影响，研究评估了区域和人口暴露的变化。总体而言，研究结果表明，随着航空交通量的增加，人口暴露量也呈上升趋势。然而，都柏林机场宽体飞机的增加进一步加剧了 2030 年的噪声影响。预计到 2040 年，第二代新型飞机的数量将增加，这将导致 2040 年的噪声等值线比 2030 年有所下降，但不会恢复到 2023 年的水平。

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
