Material physical and mechanical properties is an important indicator to characterize their characteristics. The elastic constants of wood, density, is the selection of indicators to make musical instruments sounding board. Another timber by mechanical vibration performance characteristics, namely,

The mechanics of the physical material nature is the table with its characteristics of the important indicators. The elastic constants, wood density, making musical instruments is the choice of indicators panel resonance. In addition wood affected by mechanical vibration characteristics of sound vib
