To know how sounds from several moving sound sources were perceived, we investigated a discrimination of sound images' localization of nearby moving sound sources made of two modulated noises. We examined the difference of localization by a moving direction such as clockwise and counter clockwise. Sound images were moved around the listener onto the front half-perimeter by using 8 loudspeakers. As a result, when noises were incoherent, difference limens to separate sound images were in a range between 3.6 degrees and 27.0 degrees. The overlap of power spectra of two noises hardly affected the difference limen. However when noises were coherent and power spectra of noises were identical, difference limens were approximately 9 degrees larger th an that of incoherent one. A difference of the difference limen between clockwise and counterclockwise was maximally ll.7 degrees.
