This paper presents an experiment designed to evaluate the possible benefits of sonification in information visualization to give rise to further research challenges. It is hypothesized, that by using musical sounds for sonification when visualizing complex data, interpretation and comprehension of the visual representation could be increased by interactive sonification. This hypothesis is evaluated by testing sonification in parallel coordinates and scatter plots. The participants had to identify and mark different density areas in the representations, where amplitude of the sonification was mapped to the density in the data sets. Both quantitative and qualitative results suggest a benefit of sonification. These results indicate that sonification might be useful for data exploration, and give rise to new research questions and challenges.
