Violin makers, aka luthiers, traditionally learn from hands-on experience how to craft parts and select materials to shape an instrument’s final sound. MIT engineers hope to streamline that painstaking process with their new virtual violin. It’s a computer simulation tool that can capture the precise physics of the instrument and even reproduce a realistic sound of a plucked string, according to a paper published in the journal npj Acoustics.
Unlike the more common software programs and plugins that simulate violin sounds via sampling, averaging the final sound based on thousands of notes, the MIT model is based on the fundamental physics of the instrument. “We’re not saying that we can reproduce the artisan’s magic,” said co-author Nicholas Makris. “We’re just trying to understand the physics of violin sound, and perhaps help luthiers in the design process.”
Violin acoustics has long been a hot topic of research among acousticians, particularly when it comes to unlocking the secret to the superior sounds of violins crafted during the so-called “Golden Age”—notably the instruments of famed Cremona luthier Antonio Stradivari, as well as those of the Amati family and Giuseppe Guarneri. There are plenty of variables to consider, given a violin’s acoustic complexity.
