Abstract
The characteristics of a subjective sound field formed under conditions of dichotic stimulation were studied in healthy subjects (six females and seven males) with normal auditory sensitivity upon movement of a sound image (SI) in different directions. The character and the trajectory values of the emerging subjective sound image (SSI) were determined depending on the direction of its motion and the initial interaural delay (700, 400, and 200 μs). Certain differences in the assessment of the parameters of moving sound images between the groups of male and female subjects were revealed. In female subjects, the averaged trajectory values in the right and left hemispheres were the same when the SSI moved in both directions and shortened uniformly with a decrease in the initial interaural delay. With a 700-μs delay, the trajectory values of the male subjects for all directions of motion of the SSI were the same as those of female subjects. With initial 400- and 200-μs delays, the trajectory values were significantly greater in the group of male subjects if a SI moved from the right or left ear to the median line of the head. With the method used, no interhemispheric asymmetry was revealed in the process of lateralization of moving sound images, which, under certain conditions, may be of importance for increasing the accuracy of localization of sound sources in the environment.
