Sonification is the use of non-speech audio to convey information. We are developing tools for interactive data exploration, which make use of sonification for data presentation. In this paper, model-based sonification is presented as a concept to design auditory displays. Two designs are described: (1) particle trajectories in a data potential is a sonification model to reveal information about the clustering of vectorial data and (2)data-sonograms is a sonification for data from a classification problem to reveal information about the mixing of distinct classes. Sound Examples 2+3 with Model II Data-Sonograms: These examples present Data-Sonograms of the iris data set. Iris_nm is a sonogram where the shock wave starts at the mean of all instances of class n. The local entropy S is computed using instances of class n and m. Thus the class border between class n and m is sonified.
