Résumé

A simple sound transmission model of the sealing system is presented. Finite element method and transfer function matrix were used to develop the model. Dynamic mechanical properties of seal material were measured and used as inputs to material property for the simulation. The effect of seal compression and material property of the bulb seal can be investigated. The seal vibration at the receiver was measured by the laser vibrometer.
