<p class="MsoNormal"><font size="2" color="black" face="Arial"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:black">It seems almost a truism that there is greater variability among individuals in the perception of sonified versus visualized
data sets. Yet, finding empirical studies to support this idea appears to be a challenge. For example, when representing data visually, larger data values are often represented with increasing vertical extent (e.g., taller bars in a bar graph). In most cases
observers have almost unanimous agreement on which bar is higher. In audition the same data can be represented in the domain of musical pitch. High pitch can be used to represent large data values and low pitch can be used to represent small data values.
However, there is greater disagreement among listeners in the case of sonification and the data value specified by pitch. In fact, listeners without musical training often are confused by the terms "high" and "low" as they pertain to musical pitch (Neuhoff,
Knight, & Wayand, 2002). <o:p></o:p></span></font></p>

as it pertains to data representation. <o:p></o:p></span></font></p>
