Conclusion
Spatial perception and immersion -Auditory perception

• The auditory system's perception of space differs markedly from that of the visual system. This difference goes far beyond the nature of the depth cues (table 2 ). It also concerns the ways in which spatial information is integrated.

In in situ perception, the visual field is frontal, and immersion is more mental than sensory, whereas the auditory field, which is more spatial in nature, gives rise to a predominantly sensory immersion.

• The perception of images, both visual and aural, accentuates this difference, as the reduction of the visual field to two dimensions diminishes the sensation of depth, while the perception of auditory space always remains three-dimensional.

• However, developments in image and sound reproduction techniques are moving in...
