Sonification is the use of non-speech audio to display data. Since our ears can identify particular patterns such as time series, dynamics, and expectation more strongly than our eyes, auditory display offers significant potential to perceptualise our data in new and exciting ways. Not only might we recognize new features or process data more rapidly, but as a complementary ‘visualisation’ tool, sound can help us absorb more information than visuals alone, making it particularly well suited to the analysis and presentation of multidimensional geoscientific datasets. In addition, since sound is engaging and immediately accessible, it also lending itself extremely well to public outreach and communication. In this session we invite contributions that explore any aspect of this emerging field.
