Abstract :This study is focused on the vibration analysis of the top plate of a stringed instrument, Kanun. The aim is to identify and predict the spruce and the plane tree top plate’s natural frequencies by studying an experimental method and verify those experimental results with the physical model results which are obtained by the finite element method. The method is to measure the resonant frequencies with an impact hammer test experiment and then verify those results with a 3D physical model of the plates computed with a PC in free modes of vibration. This verification is achieved only for the free modes of vibrational behaviour at this stage. Achieving this goal may lead the model to the next level to identify the fixed modes of vibration behaviour of the top plates. Finally, the results are evaluated within the range of the fundamental frequencies of the instrument. The plane tree has much more natural frequency harmonic component within the frequency range of the instrument than the spruce as one of an example.
