The aim of this study was to improve the acoustical design of a multipurpose auditorium. In the process of the study, the acoustical design plan was established before constructing a multipurpose hall and the acoustical performance was estimated after constructing a multipurpose auditorium. Moreover, RT??, SPL of distribution, EDT (Early Delay Time), C80 (Clarity), D50 (Definition), STI (Sound Transmission Index) and IACC (Interaural Crosscor-relation) were measured. Room acoustical parameters such as EDT, C80, D50, SIT, IACC were analysed. Room acoustical characteristics were estimated through comparing the measured indoor acoustical indices with some acoustical standards of multipurpose auditorium. We intend to seek for the optimum acoustic design conditions by performing Computer Simulation according to the shape of a room.
