Abstract：Statistical Energy Analysis (SEA) has become a useful technique for providing a solution to high frequency noise and vibration. Coupling loss factor (CLF) is the important parameter for SEA. Based on SEA, Finite Element Analysis (FEA) and Power Injection Method, the paper proposed a numerical calculation method of CLF for Steel-Aluminum Junction and a simulation program by MATLAB. A T-shaped plate structure connected by steel-aluminum transition junction is investigated, which is proved to be reliable by comparison with an experimental method known as Power Injection Method (PIM). In a word, it has a great significance in improving the accuracy of SEA prediction and gives useful advice to structure acoustic design.
