D 대공연장의 실내음향특성에 관한 실험적 연구

This study selected D's large performance hall, which was designed and constructed for multiple purposes and evaluated its indoor acoustic characteristics through field measurement. Evaluation indices on the temporal distribution of sound energy such as RT, EDT, D50, C80, RASTI and BR were obtained, and based on them, indoor acoustic characteristics and the generation of echoes were determined. According to the results, evaluation indices showed that the acoustic condition was satisfactory in general. In addition. if materials from the analysis are used in identifying and complementing acoustically vulnerable parts in the future, it may be possible to achieve the best acoustic condition. The materials may be applied to the acoustic design of other performance halls.
