摘要：

When the structure is forced to vibrate and multiple modes exist simultaneously, each vibration mode contributes to the total acoustic power radiated by the structure. Moreover, the acoustic radiation of each vibration mode is not independent of each other, and the coupling between them will also have an impact on the total radiated power. Mutual-radiation efficiency is an important metric to measure the ability of the coupling of different modes to radiate. In this note, for both real and complex modes, a method to calculate the mutual-radiation efficiencies by finite element method and boundary element method software is presented. Numerical examples are presented to illustrate and validate the approach.
