A Drum Shape Optimisation by Genetic Algorithms

Couro Kane and Marc Schoenauer

Abstract
     This paper deals with an optimum shape problem using genetic algorithms. We propose to find the influence of the boundary of a shape for a vibrating membrane on its pure tone. Firstly, given a spectrum, we propose a method to find the corresponding shape of a membrane. Secondly, given a ratio between the frequencies of the first fourth natural modes, we propose a method to find the shape of a corresponding harmonic drum.
