Abstract

A physically derived synthesis model of the sound generated when a ruler is twanged while hanging over the edge of a solid surface is presented. This is a sound effect used in movies, TV, theatre performances and cartoons. The model is derived from the Euler-Bernoulli equation, offering the user a set of physical parameters to control ruler length as well as the material properties. Perceptual evaluation indicates that the model can be perceived as realistic as a recorded ruler twang as well as being able to replicate sounds of similar quality as an alternative synthesis model.
