风洞模型试验支持这样的假设，即螺旋桨尖涡可能会使下游机翼表面受到比暴露在螺旋桨产生的噪声中的飞机机身侧壁更大的激励，最终将这种对入射动压的结构响应传递到机舱内部。即使在产生机舱噪声方面，结构激励的效率低于空气激励，但前者的较高水平仍然可以控制机舱噪声水平。
Wind tunnel model tests support the hypothesis that a propeller tip vortex may subject a downstream wing surface to greater excitation than would be experienced by the aircraft fuselage side wall exposed to propeller-generated noise, ultimately transmitting this structural response to incident dynamic pressure to the cabin interior. Even if structure-borne excitations are less efficient than airborne excitations in the creation of cabin noise, the higher level of the former could still govern cabin noise levels.
