This paper aims to study the location of sound sources when playing immersive sound using multiple speaker systems in a live performance environment. In particular, this performance designated the visually impaired as the audience. Therefore, the layout design of the sound source was produced by applying immersive technology so that the audience can fully enjoy and immerse in the performance. The construction of an immersive sound system by installing a number of additional speakers in the existing grand theater performance hall and the effective delivery of immersive sound to the audience are intended in this study. In order to apply the immersive sound technology, an acoustic environment that can provide immersion to the audience by studying the process of selecting and installing the most efficient system and producing sound based on the theoretical background was established. Through the experiment, the results of the directionality of implementing the location of the immersive sound source using multiple speaker systems are summarized by the location of the sound sources. As a result, the sound source can be positioned anywhere in space, such as outside the installation location of the speaker or inside the listening seat, but it is difficult to recognize the exact location according to the direction. However, due to the characteristics of the plane wave that allows multiple listeners to perceive the same direction of the sound source, the direction of the sound source was the same in all seats of the listening seat.
