In order to investigate sound image quality, white or band-limited noises with various degree of the cross-correlation coefficient are reproduced from two loud-speakers placed in anechoic or echoic chambers. Subjects are asked to make similarity judgments and some subjective evaluations of pairs of the noises. The experimental data are analyzed by Kruskal's multidimensional scaling(MDS)program. The analysis of the experimental data shows the followings:(1)sound image quality depends mostly on the width and distance of sound image, (2)the width of sound image depends on the absolute value of the cross-correlation coefficient, (3)the distance of sound image depends on the value itself of the cross-correlation coefficient, (4)with respect to physical and psychological factors governing sound image quality, there is no fundamental difference between anechoic and echoic chambers.
