본 연구는 오디토리움에서 일어나는 음향특성을 설계단계에서 미리 예측함으로써 그 설계가 음향학적 요구에 적합한지를 효과적으로 검토할 수 있는 컴퓨터시뮬레이션모델을 개발하고자 한다. 개발된 모델에 의해 음향설계단계에서 이루어지는 방대하고 반복적인 계산작업을 효율적으로 처리할 수 있게 함으로써 음향평가에 소요되는 시간과 오차를 줄일 수 있게 되었으며, 실내음장에서의 초기 시간차, 음압분포, 잔향시간, 그리고 적정 암소음유지를 위한 구조체의 차음성능을 예측하고 다목적홀의 설계사례와 비교하여 컴퓨터를 이용한 음향설계기법의 실용성 및 타당성을 검토하였다.

As can be seen in the statistics on domestic performance facilities, small or large scale of acoustic renovations seem to be unavoidable in many of those facilities due to its senility. However it is hard to find case studies which can be referred to for its acoustic renovation process. This study tried to provide a case study example of acoustic renovation for a high school auditorium which has many restrictions as a cultural heritage building. Requirements from the client and acoustic problems found through a field measurement of existing space motivated acoustic design solutions and alternatives which can improve the acoustics of the space. The whole process from the initial stage of diagnosing acoustic problems to the final stage of a post acoustic evaluation after the completion of construction was described. The result from the post acoustic evaluation suggested that reverberation characteristics of the space as well as definition and clarity have been greatly improved by applying acoustic design solutions and alternatives. However, loudness of sounds in the space didn't reach the aimed level, which is due to the limited capability of slat ceiling structure for providing strong early reflections.
