Development of a data sonification toolkit and case study sonifying astrophysical phenomena for visually imparied individuals

Abstract

Data is predominantly conveyed and analysed in a visual manner. Data sonification provides an alternative approach to data analysis, has a broader application (e.g., peripheral monitoring) and offers accessibility to an alternative cohort (e.g., the visually impaired). While there are countless data visualization tools available, producing data sonifications typically requires in-depth knowledge of audio software and/or computer programming. Research was undertaken into existing data sonification tools, and subsequently a Data Sonification Toolkit was developed using Abelton Live and Max for Live. The Toolkit was developed in particular as an alternative means of data analysis for use by multiple disciplines across a built environment firm. The key aims for the toolkit were that (1) it should be user-friendly and accessible to people without an in-depth knowledge of either Ableton or Max, (2) the sonifications produced be accurate and true representations of input data sets, and (3) the Toolkit should have the capability and flexibility to be expanded and customized by those with the expertise to do so. The Toolkit was used, in collaboration with astrophysicist Chris Harrison, to develop sonifications of astronomical phenomena for the visually impaired. These sonifications were presented at the British Science Festival in 2019.
