One of the most practical objectives to use the virtual reality system in science is to make it easy to intuitively percept complex physical phenomena. We developed a virtual reality system, called CompleXcope, which can represent "real" 3D visual environment. Since attractive physical phenomena are often so complex and tangled, the virtual reality system with 3D-sound functions is really useful for the quick comprehension of phenomena. We have recently added a sound function to the CompleXcope. In this paper we present examples produced by this aural-visual virtual reality system "CompleXcope".
