From: The Role of Visual Experience in Auditory Space Perception around the Legs
Influence of vision (perceived): Main effect of longitudinal plane (A). In the frontal space (red point) subjects reported a significantly higher percentage to perceive the sound as coming from the frontal space when the sound was delivered in the frontal space, compared to when the sound was delivered from the back (blue points). Main effect of elevation (B): subject reported a significantly higher percentage to perceive the sound as coming from the frontal space when the sound was delivered above the knee (upper arrow), than below the knee (lower arrow). Main effect of group (C): sighted group (black symbol) reported a significantly higher percentage to perceive the sound as coming from the frontal space than blind people (green symbol).
