| Outline of Final Research Achievements |
Cymbals are bronze round thin percussion instruments that are made through spin forming, hammering and lathing processes. In this study, we focus on the shape of bell (raised portion of the middle of cymbal) and the hammering process. First, we examine the relation of radiated sound and cymbal vibration based on the sound radiation efficiency and then discuss the reason why the sound radiation characteristics depend on the bell size. Next, we propose a method for predicting the vibration and radiated sound of the hammered cymbals and then discuss the reason why the hammering process changes the vibration and sound radiation characteristics.
