The process of translating quantitative data (numbers, measurements) into non-speech audio, using sound parameters like pitch, volume, tempo, and timbre to
represent different variables. It turns spreadsheets into symphonies, allowing patterns, trends, and anomalies in datasets to be perceived through the human ear, which can
sometimes detect subtle rhythms and shifts that the eye might miss in a graph.
Data Sonification Example: A climate scientist sonifies 100 years of Arctic
temperature data, mapping each year to a note. Rising temperatures cause a slow, creeping rise in pitch. The listener hears a haunting, accelerating upward glissando over the century, making
the abstract trend of
global warming viscerally, emotionally audible in a way a line chart often isn't.
