Investigation of Numerical Method of Xylophone by Finite Difference Method in Time Domain
Hideo Tsuru (Nittobo Acousrtic Eng.) EA2009-34
Abstract (in Japanese) (See Japanese page) 
(in English) Recently, the numerical simulations in time domain is applied to practical analysis of musical instruments. The analyzed instruments are various kinds such as piano, violin and xylophone. Here, we investigate time dependent properties of the mallet instrument by numerical simulations. A xylophone is an elastic material which has a non uniform cross section. A dynamical equation of the xylophone is modelled by Timoshenko's theory or Mindlin plate theory. Viscoelastic and fluid mechanical damping effects are also taken into account. Vibrational motions of the elastic bar are simulated numerically through a finite difference method. Since the order of the spatial differential in the coupled partial differential equations is larger than that of the time differential, an implicit method is used to stabilize its numerical behaviour. The simulation can predict transient and frequency characteristics which are influenced by the change of shape and impact point and duration. The numerical result is auralized by a digital analog converter. It is concluded that the damping effects are important to reproduce a realistic sound.
