In this study, we prepared a stage sound field using virtual sound source distribution and conducted examinations of the acoustic effects of initial reflected sound on the stage, from the side walls, ceiling and the audience area on subjective evaluations by solo performers under conditions of simulated stage sound field in which the direction, energy and arrival time of the initial reflected sound group surrounding the performer were systematically varied. As a result, we found that lateral reflected sound has the role of returning the primary sound to the performer on the stage and that reflected sound from the ceiling, which arrives slightly later than the lateral reflected sound, is linked to the quality of the response and is also a factor in "ease of performance". In addition, we also realized that the forward reflected sound from the audience area gives the performer the impression that the sounds of the performance are reaching the audience and that this impression is not only influenced by the volume of the reflected sound from the audience area but also the arrival time of the reflected sound.
