Spatial inputs from the auditory periphery can be changed with listener's various movements relative to the sound source. Nevertheless, humans can perceive a stable auditory environment and appropriately react to a sound source. This suggests that the inputs are reinterpreted in the brain, while being integrated with information on the movements. Little is known, however, about how these movements modulate auditory perceptual processing, especially under linearly moving environment. We investigate the effect of linearly self-motion on auditory space representation. Results of our experiments showed that the sound position judged as being located at the subjective coronal plane was displaced compared with the the listener's physical coronal plane. This distortion was observed irrespective of the style of the self-motion (active or passive). Moreover, the distortion was observed both with and without vestibular stimulation. These results suggest that self-motion information, irrespective of its origin (vestibule or any other sources), is crucial to evoke this distortion of auditory space perception.
