| Abstract(in English) | This paper reports the assessment results of frequency dependency of perceptual sound distance using a phase shift auditory distance control method. Kurozumi et. al. have been reported that if the phase difference between left and right audio signals is controlled from 0 degree to 180 degree, the perceptual distance of sound image is changed from front to the back of the head. We performed several subjective assessments to examine the distance perception of octave band noise. As the results of the left and right loudspeaker reproduction in anechoic room, it was found that distance perceived by the phase shift distance control method has frequency dependency, and that distance perceived for 1000Hz or more octave band noise is not significantly different even if the phase difference is controlled. On one hand the results of the headphone reproduction are different from the above results of the loudspeaker reproduction. |
