This study deals with the development of an automated computer optimization procedure for the design of acoustical space. An analysis scheme utilizing a ray tracing approach is used to calculate the acoustical response at different locations in the space. The response characteristics are utilized to quantify the acoustical merit at any location based on a developed set of criteria. An efficient search technique is employed to seek, for any given floor and stage areas, the geometric and acoustical design parameters which maximize the considered merit function, subject to any constraints imposed on the design. A simplified example of a concert hall design is considered for illustration. Considerable improvement in the acoustical merit (as defined in the paper) of such halls can be achieved by the use of the optimization scheme. The developed procedure shows excellent potential for the application of optimization techniques to the design of enclosed spaces.
