Abstract
This paper discuses the way to reduce the noise and vibration of thin plate structures. This paper focuses on the musical saw, a kind of musical instrument. The musical saw is thin plate and for playing the instrument, it is need to bend the saw as S-curve. Also thin curved plates are used for various mechanical structures to enhance the stiffness. In case that the curved plates have same dynamic characteristics as musical saw, the plates became noise source. Through the experiment and numerical investigation for the relationship between the mode shape and radiation sound, it is shown the dynamic characteristic of thin plate which contributes the radiation sound.
