We used finite element method with ANSYS software to simulate acoustic materials vibration. In this thesis, we used sound intensity probe measure the sound transmission with different measurement methods. Transmission loss values were obtained and compared analysis of potential errors. The experimental proper way and the accuracy of experimental values are assured. We also used different spring coefficients with the same impulse force to calculate modes, and displacement, and radiation of sound pressure. In simulation results, we found that the proper structure (stiffness) damping can enhance transmission values of low frequency. Der-Yuan Liou 劉德源 2010 學位論文 ; thesis 84 zh-TW
