Top plate vibration analysis of the kanun

This study is focused on the top plate vibration analysis of the Kanun instrument. The aim is to identify and predict the spruce and plane tree top plate’s natural frequencies by using a truly working and confirmed physical model. The method is to measure the resonant frequencies with a 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 behavior at this stage. Achieving this goal may lead the model to the next level to identify the fixed modes of vibration behavior of the top plates. Finally, the results are evaluated within the range of the fundamental frequencies of the instrument. Plane tree has much more natural frequency harmonic component within the frequency range of the instrument than the spruce as one of an example.
