Abstract

The matrix expression for SEA and the formulas for determining the mode number, the internal loss coefficient and the coupled loss coefficient are given. The experiment on the box model shows that the calculation results and experimental ones are in good agreement. Hence it is proved that SEA is an effective method for predicting ship structure-borne noise.
