Abstract
The aim of this study is to clarify the relationship between the vibration of violins made by Antonio Stradivari and the acoustic radiation around it. The highly precise geometry of the violin was determined with a micro-computed tomography scanner, and the material properties of the violin body (spruce and maple) were set as the orthotropic properties in the numerical simulation. Then, the numerical simulations coupling the vibrations by a forced oscillation on a bridge with the acoustic field pressure around the violin were performed. Furthermore, the sound pressure emanating in a huge rectangular box was successfully calculated by large scale computing and the open-source parallel acoustic analysis software.
