本文评述了气动声学中六个领域的研究现状和重要性，包括（i）涡量和声量分别产生声和涡量，（ii）在非定常前缘和后缘流动中应用库塔条件的基础和结果，以及（iii）在弱离散音调强迫的影响下，抑制或放大射流中的宽带流体动力学场和声场。这样做的目的也是为了促进人们再次接受声学作为流体力学的一个重要分支。
This article gives a review of six areas of current activity and importance in aero-acoustics, including (i) the generation of sound and vorticity by vorticity and sound, respectively, (ii) the basis for, and consequences of, the application of a Kutta condition in unsteady leading- and trailing-edge flows, and (iii) the suppression or amplification of broadband hydrodynamic and acoustic fields in a jet under the influence of weak discrete tone forcing. The intention is also to promote acceptance once again of acoustics as a serious branch of fluid mechanics.
