AB  - In the present study, we measured threshold of interaural level difference in standard stimulus (ILDs) through the interaural time difference in variable stimulus (ITDv) and tested just notice difference of interaural time difference in standard stimulus (ITDs) by the interaural level differences in variable stimulus (ILDv) for sine wave over a frequency ranging from 150 to 1500 Hz at some lateral positions of sound image. Two separate experiments were conducted based on two alternative forced-choice (2AFC) and 1 up/2 down adaptive procedure. We could explore the relative contribution of Interaural Level Difference (ILD) and Interaural Time Difference(ITD) to sound localization as a function of position and frequency from these experimental data. The results showed lateral discrimination between stimuli are not difficult at frequencies of 350, 450, 570, and 700 Hz when we tested JND of ILD in standard stimulus and the auditory system is easier to discriminate two sound images and is more sensitive to localize the lateral positions of standard stimulus as frequency is varied from 700 to 1500 Hz when we measured JND of ITD in standard stimulus.
