| 概要 |
The final goal of this study is to clarify which kind of sound field is desirable for musical performers on the stage in auditoria and to propose a new method to evaluate stage acoustics. In this pape...r, as the first step of the study, an acoustical measurement is performed in three actual halls, and ST index and the directional characteristics of reflections are discussed. The results show that the directional characteristics of reflections vary with the position on the stage and there exist some points that have different directional characteristics of reflections even though their values of ST are equal. This suggests that ST is not sufficient to evaluate the ease of performance and it is necessary to examine a new evaluating method considering the form of musical performance.続きを見る
