Abstract

Genetic algorithms (GAs), a form of evolutionary computing, have been applied to the design of concert halls. The application of a GA to a system for optimizing a concert hall in terms of four orthogonal factors of a sound field is discussed. The first model was an optimization of the proportions of a hall of the typical shoebox type. The second model is the optimization of the plan of the hall. The results show that the optimized form of the first model is similar to Grosser Musikvereinsaal. The second model took on different characteristics according to the preference for which it was optimized. A leaf-shaped plan is a typical result of the maximization of the scale values of preference for the audience area.
