,Measuring Vibration Modes of Violins’ and Other Instruments’ Plates,o 5000 Hz. Modal analysis gives the theoretical parameters of the vibration of musical instruments. Modal testing allows experimental identification of different parameters of a vibrating instrument such as natural frequency, modal damping and the mode shapes. The non contact vibrometry allowed a de

Material Properties and the Modes of Vibration of the Concert Harp Soundboard,s. Finite element analysis has shown that these modes strongly depend on the value of Young’s modulus of the resonance wood along the fibres‘ direction. The soundbox of semi-conical shape is built up by moulding with veneer sheets and by bonding one decorative hardwood veneer layer in curly maple or
