Data sonification
File:Geiger counter sound KCl.oga Data sonification is the presentation of data as sound using sonification. It is the auditory equivalent of the more established practice of data visualization.
Process
[edit | edit source]The usual process for data sonification is directing digital media of a dataset through a software synthesizer and into a digital-to-analog converter to produce sound for humans to experience.[1][2][3] Benefits to interpreting data through sonification include accessibility, pattern recognition, education, and artistic expression.[4]
Applications
[edit | edit source]Applications of data sonification include astronomy studies of star creation,[5] interpreting cluster analysis,[6] and geoscience.[7] Various projects describe the production of sonifications as a collaboration between scientists and musicians.[8][4][9]
A target demographic for using data sonification is the blind community because of the inaccessibility of data visualizations.[10]
One of the earliest examples of data sonification is the Geiger counter, which measures ionizing radiation through sound.[11] Another notable example of data sonification is NASA's processing of images from space telescopes into sounds.[12]
