Pitch change, sonification, and musical expertise: Which way is up (original) (raw)
Yet, despite the ubiquitous use of frequency change in auditory display, and the wealth of knowledge and data relevant to the perception of pitch, there is very little empirical work that addresses the appropriate mapping of frequency change to changes in the variables that are to be sonified. Some recent work has examined the relationships between the conceptual aspects of the variables and the perceptual characteristics of the acoustic signal, as well as the scaling factors that would best represent changes in variables with changes in sound . Specifically, this recent work has addressed important questions regarding whether an increase in an acoustic dimension (e.g., rising frequency) should represent an increase or a decrease in a variable dimension, and what magnitude of acoustic change is appropriate to accurately represent a given magnitude of change in the variable.
