The purpose of this study is to investigate the relation between acoustic characteristics of sound field and the fundamental room shape of auditoria from the point of view of symmetric/asymmetric features of the space, and to make clear the acoustical validity of asymmetric room shape in acoustic design. In this paper, the spatial distributions of some acoustic measures are investigated in auditoria models, whose shapes are systematically varied in plan, by means of geometrical acoustic simulation. The results show that there is a significant difference in the attenuation of reflected energy due to distance between the varied shapes, and the effect of asymmetric room shape on the acoustic property is confirmed. It is suggested that the adoption of asymmetric configuration of auditoria is useful in acoustic design of optimal sound field.
