对流致声和声源的实验研究需要一个低干扰噪声和抑制不必要声源的适当环境。为了研究流固耦合噪声，设计并实现了一个低噪声风洞。本文概述了设计标准和规范，并沿着该设施的气动声学和空气动力学特征。翼型自噪声研究的适用性进行了探讨，并提出了与模型翼型的第一次测量。文章最后对未来的应用前景进行了展望。
Experimental investigation of flow-induced sound and sources of sound necessitates an adequate environment of low interfering noise and suppression of unwanted sources of sound. In order to investigate the sound from fluid-structure interactions, a low-noise wind tunnel has been designed and implemented. This paper gives an overview of the design criteria and specifications, along with an aeroacoustic and aerodynamic characterization of the facility. The suitability to airfoil self-noise studies is explored and first measurements with a model airfoil are presented. The paper concludes with an outlook on future applications.
