Abstract
In this study, we measure the vibrations of the unattached free violin top plate and back plate. We apply the pressure-based conformal holography with a hologram and a source surface coupling (PCHHS) as BEM-based acoustical holography in order to measure the vibration eigenmodes of the actual arching violin plates. We reconstruct and visualize the distributions of the sound pressure and the particle velocity on the surface of the violin plate from the measured hologram data in the sound field. The important vibration eigenmodes to know the acoustic characteristics of the violin plates are clearly reconstructed with good resolution.
