Two parameters, namely modal number (Nm) and modal overlap factor (Mo), are used as the indicators of the reliability of SEA prediction. It is suggested that Mo>1 and Nm>5 can be used to judge if the SEA prediction is reliable in prediction of plate vibration. In the mid-frequency, those conditions are hard to satisfy. Although it takes long time and great expense and even it is impossible to apply finite element analysis to the whole structure, it is economically to calculate a local single part and coupled parts. If the value of input power and coupling loss factor can be replaced by the value calculated by FEM, the precision of SEA can be greatly improved. Calculation example was given and the validity was proved.
