Over the last few months, CATEA’s SciTrain project has been working with the Georgia Tech Sonification Lab to develop training modules for their preliminary sonification software known as the Sonification Sandbox. Sonification is the process of turning visual graphs and data into auditory graphs which can be used by people with and without visual impairments to better understand concepts like point estimation, trends, etc.

Instead of hearing an auditory description or using a tactile graph, students can use a system of ticks and tones to hear the graph. In theory, these graphs can provide more information than auditory descriptions and take less time to create than tactile graphs. The data can be entered manually or using a Microsoft Excel .CSV file. I encourage you to try it out and send me any feedback!

Try the Software!

The SciTrain section on auditory graphs provides a brief introduction to the software as well as a link to download the software(beta) for free.
