음장의 잔향 시간 제어 시스템 설계에 관한 연구 = A design of reverberation time control system in sound field

다국어 초록 (Multilingual Abstract)

In this study, a system that modifies the acoustic characteristic of a sound reproduction field rh an arbitrary reverberation time-frequency characteristic is developed. And then was examined a signal processing method that controls the reverberation time of each frequency band independently, and designed an algorithm that adjusts the reverberation characteristic of sound field to a desired characteristic. A computer simulation of the algorithm shows that it can make a highly precise approximation. The validity of this method, which creates envelopment and natural reverberation, was clarified through listening test applied to some real sound fields.
