Prediction of Vehicle SEA Model Input Parameters a Sound Package

Article of Honda R&D Technical Review Vol.15 No.1


This paper describes a method for prediction of automotive sound package acoustical characteristics. This method is based on the transfer matrix approach and is applied to calculate the TL and absorption of multilayered insulation components from the acoustical impedance of each layer. The predicted results are necessary as fundamental input parameters of SEA vehicle models. The accuracy of this method was verified by comparing the predicted TL and absorption values of trimmed components with measurement results.
