Abstract
A code was written to explore, in real-time, experimental operational deflection shapes up to 5 kHz of a violin soundbox. The animations can be rotated and zoomed using the mouse, while the developed graphical user interface (GUI) allows controlling the frequency, amplitude, and frame-per-second rate. Also, some parts of the model can be hidden to improve the visualization of specific details of interest. The measurements—performed by students as laboratory exercise—include the ribs and not only the plates as it is traditionally done, thus the vibrations of the soundbox can be analyzed as a whole. Since the GUI was developed under a cross-platform open-source software (scilab), it can be easily installed and used as an educational tool for traditional in-person learning or online learning.
