Oud is a plucked musical instrument played in many countries. This historical musical instrument involves many structural parts effecting its acoustics and sound quality. This study aims at investigating the vibration characteristics of an oud soundboard for free-free and fixed (at its edges and no back cavity) boundary conditions. Also as a final step, the soundboard-air cavity coupled modes were measured by assembling the soundboard and body together. Frequency response function (FRF) measurements were carried out by experimental modal analysis technique to reveal the dynamic behaviour (mode frequencies, mode shapes and damping coefficients) of the soundboard which has a conventional seven parallel strutting configuration.
