The Effects Of The Body Vibration Modes Of A Stringed Instrument, Oud, On Its Process Of Sound Production
The stringed instruments consist basically of various number of stretched strings and a large surface body where sounds are produced via transmitting vibrations from the strings during playing. The bodies designed specifically for each instrument are the most important parts of the stringed instruments that determine the sound character. Therefore, it is important to examine the vibration modes of the instrument body and to reveal their effects on the sound production process of the instrument. In this study, roving hammer test, bridge mobility measurement and sound radiation analysis were applied to ten ouds. The findings were presented in a comparative way on the same graph, and, the effects of natural frequencies, mode shapes, phase relations and damping values on the sound production were investigated.
