Abstract :
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.
