Research Abstract

When we move in an environment, auditory input to our ears dynamically changes. This likely interferes with accurate sound localization because cues for auditory localization are primarily coordinated and centered on the head. Nevertheless, in reality, we perceive a stable auditory space. This requires that the brain interpret auditory signals in reference to signals about head and body movements. Here we investigated how visual and vestibular self-motion information affects auditory space perception. The results showed the systematic distortion of auditory space during visual and/or vestibular stimulation, suggesting the adaptive bias in the auditory system to avoid obstacles and any incoming dangers.
