The effect of linearly moving sound image on perceived self-motion with vestibular information

The effect of linearly moving auditory information on self-motion perception with vestibular sensation was addressed and found that the auditory information influences self-motion perception. Six male and six female adults with normal hearing acuity participated in the experiment and a swinglike device was installed in the anechoic room to provide vestbular information. It is seen that almost all listeners perceived larger leftward self-motion in the L-F condition than in the other conditions. The results of a multiple comparison based on pairwise comparisons show that the value of L-F condition is significantly larger than those for the other conditions. It is also found that almost all listeners noticed the difference between the L-F and R-F conditions, whereas they did not notice the difference between the F-F and None conditions.
