Abstract 
Sonification is th euse 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.
