실내잔향모델: 5자유도 잔향 모델

Abstract

초록 In architectural acoustics, many objective measures of the perception of room reverberation have been proposed(1,3). In this paper a room reverberation model is proposed based on such objective measures. We select five primary measures such as reverberation time, early decay time, initial time delay gap, clarity, and RID ratio, and we model a sound energy decay curve using them. The model integrates the measures and it is useful to investigate the relationship between them. The limitation of the proposed model is investigated, when it is applied to artificial reverberator.
