A Study on the Room Acoustic Characteristics according to the Layout System of Speakers in the School Gymnasium

학교체육관에서 스피커 배치방식에 따른 실내음향특성에 관한 연구

The aim of this study is to provide fundamental data for acoustic design by analyzing the room acoustic characteristics according to the PA system used in the school gymnasium. The measurements were carried out accordance with the ISO 3382. The sources used in this study were four types; omni-directional, centralized, distribution, the combination of centralized and distribution sound source system. Omni-directional system is recommended by ISO for the acoustic test and the others are installed on the wall, column and ceiling in the school gymnasium for sound reinforcement.
