Computational modelling of string-body interaction for the violin family and simulation wolf notes

Significance of output:

This article describes a significant advance in computational modelling of bowed string instruments (violins, cellos etc.) that allows the prediction and investigation of 'Wolf Notes'. These are notes whose sound quality is impaired by complex, non-linear interactions between the string and the body. Being able to model this phenomenon allows instrument makers to design their instruments so that the effect of wolf notes can be reduced. The method is also useful in the design of structures such as disk brakes that are affected by self-excited friction oscillations causing brake-squeal.
