自20世纪50年代喷气机时代开始以来，气动声学在近70年来一直是一个活跃的研究课题。虽然基本上是流体力学的一个分支，但气动声学已经发展成为一门具有明确定义的科学和技术使命的学科，即对声音的产生和向外传播建模，更重要的是开发新的降噪技术。鉴于民航不断扩大，而航空噪音管制却日益严格，进一步减少飞机噪音势在必行。此外，来自不同领域的未开发噪声源，如无人驾驶飞行器、风力涡轮机和即将问世的城市空中交通工具产生的噪音，也带来了进一步的挑战。
Aeroacoustics continues to be a subject of active research now nearly 70 years since its genesis in the 1950s at the dawn of the jet age. Although fundamentally a branch of fluid mechanics, aeroacoustics has grown into a discipline of its own right with well-defined scientific and technological missions, namely, modelling both the generation and outward propagation of sound, and more critically developing novel noise-reduction techniques. Given the ongoing expansion of civil aviation set against the introduction of ever more stringent regulations on aviation noise, it is imperative to reduce aircraft noise even further. Moreover, unexplored noise sources from diverse areas, such as that generated by flow over unmanned aerial vehicles, wind turbines and the forthcoming urban air mobility vehicles, present further challenges.
