Distance Perception and HRTF
Reproduction and control of sound image distance are also important elements in three-dimensional acoustics. However, quantitative reproduction and control of sound image distance have not yet been realized. In particular, sound images in the front direction are often localized inside of the head or extremely close to the forehead. In this chapter, the cues for the perception of sound image distance are described. In particular, the relationship between the sound image distance and the incident direction is discussed in detail.
