The Effect of Resonance Wood Quality on Violins Vibration

The aim of this paper is to highlight the correlations between the anatomical quality of the resonant wood (spruce and maple) and the dynamic response of the violins. In this study were analyzed 28 violins, seven from each structural quality class of wood (A, B, C, D), according to the classification made by manufacturers. The violins were analyzed in terms of physical parameters (width of annual rings, proportion of late wood, proportion of early wood, wavelength of sycamore curly grains) after which they were dynamically tested, determining the dynamic parameters. The results of experimental investigations showed that the frequency response of violins is closely related to the anatomical quality of the wood in the structure of violin boards.
