Sonification examples
Chapter 8: Sonification ModelsIn Chapter 8 of the thesis, 6 sonification models are presented to give some examples for the framework of Model-Based Sonification, developed in Chapter 7. Sonification models determine the rendering of the sonification and possible interactions. The "model in mind" helps the user to interprete the sound with respect to the data.
Data Sonograms use spherical expanding shock waves to excite linear oscillators which are represented by point masses in model space.

8.2 Particle Trajectory Sonification ModelThis sonification model explores features of a data distribution by computing the trajectories of test particles which are injected into model space and move according to Newton's laws of motion in a potential given by the dataset.

In this chapter, two extensions for Parameter Mapping Sonification are introduced. The first is the Auditory Legend, which provides the limits and an average sonification for the attributes of an instrument. The second is Multidimensional Perceptual Scaling, a technique to combine MDS and PCA in such a way that sonifications are obtained that reveal groupings in the data without the need for extensive parameter tuning.

In this chapter, sonification is applied in 3 domains. Two of them are concerned with the analysis of data which is ordered in time. Sonification is here devoloped to assist the monitoring of dynamical features. The third application is concerned with identification and comparison of high-dimensional patterns. Here sonifications are developed that allow a user to interact with an auditory map by browsing elements of a visual display to query an auditory presentation.
