We developed a method of estimating the direction of sound image localization. Our method is based on the sound pressure distribution in the vicinity of a listener. In the experiment, band noises that only differ in phase were produced from two loudspeakers. We determined what relation existed between the subjective direction of the sound image localization and the objective sound pressure distribution in the vicinity of the listener. We found that an azimuth of localization can be expressed as a linear combination of sound pressure levels in the vicinity of the listener. Our method can be used to estimate azimuths with a high degree of accuracy and to associate phase differences with azimuths. Therefore, it can be used to design a system for controlling virtual sound image localization.
