As examples,the resonances near 121 and 240 Hz are caused by the 1st and 2nd wave modes of the air in the vertical dimension of the van’s interior cavity.Engine orders 1,2,3,3.5,4 and 6 are all present,and coincide with some of the predicted cavity mode frequencies at this engine speed.

比如,在121和240赫兹(Hz)的共振是由在汽车内部空腔垂直空间一、二级波(
叠加)模型造成的.发动机秩序1,2,3,3.5,4和6都在这里,这跟某些在特定
发动机速度下的腔模型频率预测是一致的.
