Data Sonification

The systematic mapping of data values to non-speech audio parameters such as pitch, volume, rhythm, timbre, or spatial location to make datasets perceivable through hearing. Data sonification is a key accessibility technique for making charts, graphs, and other data visualizations accessible to blind and visually impaired users. Unlike simple audio alerts, data sonification preserves the structure and relationships within data, allowing listeners to detect trends, outliers, clusters, and patterns through auditory perception.
