Abstract
We propose a numerical method to predict the noise transmission loss of a resin composite cover, which considers the effect of the shape and the material properties of the microscopic reinforcements in a resin-composite. The mean material properties of the material are calculated with the homogenization method and the acoustic structural coupling analysis is made with the obtained material constants. The calculated results show that the sound insulation levels are affected seriously by the shape or rate of the reinforcements in the material, which suggests that the present method can be a good numerical method to determine the reinforcements in a resin to improve the sound insulation ability.
