摘要：
Stringed musical instruments are part of worldwide culture since ancient times. The family of lutes in particular dates back to 3000 B.C. Historic research reveals that these musical instruments had spread all over the world as a consequence of wars, emigration and cultural influence and slowly evolved while moving geographically. Among these, Italian mandolin had a great development and diffusion all over the world.
Mandolins soundboards are traditionally built with red spruce (picea abies) because of its excellent acoustical properties. Despite numerous scientific works can be found in the literature that relate wood properties to the acoustics of bowed and plucked instruments such as violin or guitars, not much can be found regarding traditional Italian mandolins.
In our work, we systematically analyzed the wood acoustics performance, applying non destructive methods that allows one to measure the wood properties, developeing a figure of merit that considers its anisotropic nature and classify wood for stringed musical instruments according to its acoustic performance. On a parallel track, we characterized several antique and modern mandolins to measure their acoustic response and understand how the sound is related to the particular instrument design and materials. This study was supported by several experiments on wood samples and finished instruments, as well as finite elements simulations that allowed us to understand how the wood properties reflect on the sound.
Our approach highlighted that there is still is room for improvement in terms of musical instrument design and realization, an interesting challenge for the new generation luthiers. In this regard, we realized three test-bench instruments, taking advantage of the knowledge acquired during the study in order to improve or modify the instrument characteristics in terms of sound intensity and timbre
