碩士 === 國立臺灣大學 === 電信工程學研究所 === 87 === The subject of this thesis is in examining simulated results of the physical modeling of several structures of musical instruments. Physical modeling is one of the promising methods of sound synthesis. By modeling the mechanism of sound production, physical model synthesis provides not only the relationship between the vibration and acoustic phenomena of musical instruments, but also the digital sound with the best auditory quality. Three kinds of musical instruments are simulated in this thesis: (1) membranes : The equations of this problem are solved directly. (2) rectangular plates : For plate problems that do not have exact solutions, we utilize the finite element method to obtain those approximate solutions. (3) guitar : Based on a simple physical model of strings and a soundboard, we are able to simulate the sound of a guitar. Simulated sounds are consistent with our listening experiences.
