Data visualization communicates information through visual representation in the form of charts, graphs or maps. Data sonification communicates information through audio representation using music, sound or speech. Turning data into sound has advantages. Just like in the cinema, sound adds another layer to understanding. Sound does not require you to look at a screen. You could be anywhere in a room and hear the differences in the output. It can be used by itself or as a complement to visual systems. The representation of the data is as “true” as a visual rendering and any anomalies can be heard, identified and acted upon.
