A 1/10 scale model was introduced as an efficient tool to predict acoustical qualities of multi-purpose halls It was constructed to predict the acoustical properties, and to complement and adjust the architectural components on room acoustical characteristics of K-performing arts center The materials of scale model such as seats and audiences, absorption banners were selected through measurements of absorption coefficient In a 1/10 reverberation chamber and the absorption coefficients due to air-absorption With relative humidity was also Investigated As a result, It showed that types and parts of material and arrangement of specimen had much effects on absorption coefficient, and air absorption resulted In a significant decrease In absorption coefficient at high frequency In addition, the reverberation time of scale model was measured In occupied seats and the effect of absorption banners on the ceiling and side walls was also investigated Results showed that reverberation time of scale model showed a decrease of 0.5s by banners on the ceiling, whereas those on side walls had a little effect on reverberation time
