For the visualization of a sound field, a widely used method is the superimposition of the sound information onto a camera view. Although it effectively enables the understanding the relationship between space and sound, a planar display cannot resolve depth information in a straightforward manner. In contrast, a see-through head-mounted display (STHMD) is capable of representing three-dimensional (3D) vision and natural augmented reality (AR) or mixed reality (MR). In this paper, we pro-pose a system for the measurement and visualization of a sound field with an STHMD. We created two visualization systems using different types of STHMDs and technolo-gies for realizing AR/MR and a measurement system for a3D sound intensity map, which can be used together with the visualization system. Through three visualization ex-periments, we empirically found that the stereoscopic viewing and the convenient viewpoint movement associ-ated with the STHMD enables understanding of the sound field in a short time.
