Modern aeroacoustics was founded when James Lighthill published his 1952 paper entitled “On Sound generated aerodynamically, Part I: General Theory” (Proceedings of the Royal Society of London, A211: 564-587.) At the time there was the problem of very noisy jet aircraft. Great strides have been made in making aircraft powered by jet turbines quieter. The study of aerodynamically or hydrodynamically generated sound, in both air and water, has continued since the initial Lighthill paper was published. The progress in both theoretical and experimental understanding on how sound is generated, particularly in response to fluid-structure interaction.

Aeroacoustics has firmly established acoustics as a branch of fluid mechanics. Aeroacoustics is, thus, a classical field theory based on fluid mechanics. Its applications, and potential applications, are numerous, such as in the areas of noise control and musical acoustics. We at CReSS LLC have applied aeroacoustics to understand the physics of speech production.
