Sonification renders time-varying data through pitch and timbre changes
Evidence
In this experiment, the rising arpeggio shown as response (A) is perceived as expected for stimulus (A) when all the note timbres are the same. However, the response changes to two separate falling arpeggii, shown as response (B), if note timbres are alternated between two timbres represented by the different notehead shapes, and “the difference in timbres is increased” as shown for stimulus (B). This is described as timbral streaming (e.g., Bregman, 1990). — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1629 (
