The purpose of this study is to understand the characteristics of optimum acoustic condition for an orchestra conductor on the stage. In this paper, as the first step of this study, by using model sound field, experiments to measure the subjective easiness of conducting were carried out and following results were obtained. 1. Easiness of conducting is influenced by reverberation time and the optimum value is different from performer and audience. 2. Easiness is also influenced by long path echo (LPE) and easiness is reduced by the detectability of echo. But some conditions can be accepted despite detectable. 3. In the combined condition of reverberation and LPE, LPE dominantly influences on the easiness. 4. Performer and conductor differently evaluate the easiness in the same stage acoustic condition.
