In accordance with increase of the leisure time due to the recent economical development of the people, since the interest on the cultural performance becomes high, the construction of various performance hall is on increasing in domestic. However, in case of the multi-purpose hall constructed in domestic, because the various genres performances are performed in the one space without any special variable equipment, those of many problems have been raised that unable to satisfy the acoustic capability suitable to the purpose of performance. In case of the performance place such as the multipurpose hall, it is the requiring real situation that the variable typed system-equipped performance hall which able to adjust the acoustic characteristics suitable to each performances. Accordingly, this study has ever predicted the optimized acoustic performance through computer simulation before-opening the hall, also has ever evaluated the acoustic performance through the actual survey after-opening the hall. It is considered that such study result could be utilized as the most useful material when construction the similar multipurpose hall equipped with the variable typed system, hereafter.
