In this project we focus on the family of bowed string instruments, whose sound depends on a wide variety of physical parameters, such as resonance frequencies, Chladni patterns, wood density, string tension and structure, speed of propagation, etc. We will study how the luthiers handle all these parameters in the process of creation of the instruments (violins in particular) and we see the difficulties they find and their possible influence on the final sound. The final goal of the project is the creation of a computer tool in Matlab for the luthier of bowed string instruments to analyze certain acoustic parameters during the manufacturing process, in order to ease the current procedure and improve the sound quality. In addition, it is also intended to use these data to investigate possible relationships between the different physical parameters and their consequences on the product.
