Conventionally, when grasping the energy flow of sound, the acoustic intensity is calculated and expressed in two dimensions with a vector. In recent years, the technical development of virtual reality(VR), augmented reality(AR) and mixed reality(MR) has been remarkable as a means for representing three-dimensional spatial information. Therefore, VR was applied to grasp the energy flow of sound. In order to make it easy to express in VR, we adapted streamlines to the acoustic intensity. As a result, it became possible to express the energy flow of sound clearly in a three-dimensional space.
