Abstract
Prediction method of acoustic noise is necessary in product design. In this paper, SEA (Statistical Energy Analysis) method is used to predict transmission path of acoustic noise and vibration for large-scale structures. Accuracy of SEA depends on SEA parameters (Damping Loss Factor, Coupling Loss Factor, and so on). In this study, authors obtained SEA parameters of a model for transmitted sound through a panel by using 3 elements PIM (Power Injection Method) and 2 elements APIM (Approximated Power Injection Method) experimentally. Then validity of the parameters is discussed by comparing the experimental values obtained in this study with theoretical values obtained by Mass Law.
