ステージ上の音響条件に対する指揮者と演奏者の主観評価の差異: オーケストラを対象としたステージ音響設計に関する基礎的研究

摘要

The purpose of this study is to find the difference of subjective evaluation properties for stage acoustic condition between conductor and players. In experiments, conductor and two players play music under some modeled sound fields as stage acoustic condition and then they evaluate condition subjectively. As a result, followings were obtained.rn1. There is a difference of tendency in subjective evaluation of Reverberation Time between conductor and players.rn2. ST1 affects only the subjective evaluation of players.rn3. The subj ective evaluation of conductor is affected by Early Decay Time rather than RT, while that of players is affected by RT rather than EDT.rn4. Conductor perceives Long Path Echo of high level as more negative than players.%本論文では音楽構築時における指揮者と演奏者の「音場に対する好ましさ」を同一のステージ音響条件において同時測定することにより、両者の音場に対する評価傾向の違いや、評価の差異を明らかにした。得られた知見を以下にまとめる。
