The mapping of two- or three-dimensional data onto a spatial auditory display is limited by a
number of psychoacoustic factors (this is, in fact, true of any sonification using spatialization).
Localization by humans is influenced by the type of signal and the familiarity of the sound.
In addition, sensitivity to azimuth, confusion of placement in front or behind, and other
aspects of auditory spatial perception limit the specificity with which space can be used in
PMSon.
