the role of hearing in virtual reality experience

Sound is an important part of virtual reality. As humans have two eyes for sight, people have two ears for hearing. As with vision, one's brain puts together two close, but distinct, sensory inputs to make three-dimensional inferences about the source of the signal. It decides three-dimensional location and movement of the source by analyzing: the lag between when each ear hears the sound; level and changes of sound frequency and volume; alteration of sound waves due to obstacles; and sound echoes reflected off environmental surfaces.

If you wanted to specify total sensory potential for communication from environment to human and the sum of modality output for communication from human to setting, then one could identify a threshold percentage that should be actively involved by computer simulation to be categorized as Virtual Reality (VR). Nonetheless, quantifying sensory data processing potential and summing communication potential across different senses and mechanisms is difficult. An alternative way to specify the base-line amount of human to computer interaction to be virtual reality is the "four-fold" approach. Virtual reality should be (1) responsive, (2) immersive, (3) immediate, and (4) advanced. See also Virtual Tours Crookston, Minnesota for interesting subjects regarding virtual reality.
