Auditory Display / Sonfication
• 1992 - 1st International Conference on Auditory Display (ICAD)
• Sonification = use of audio to convey information• Applications:
– Auditory Graphs
– Attensons
– Earcons
– Auditory Icons

Methods in research
Audification:• mapped to 1-d• ev. transposed
Parameter mapping:
Model-based sonification
![Page 13: Sonification in Theoretical Physics Katharina Vogt Prof. W. Plessas Prof. R. Höldrich Todtmoos, 12th september 2007](https://reader036.vdocument.in/reader036/viewer/2022062515/56649d265503460f949fcf09/html5/thumbnails/13.jpg)
Advantages
![Page 14: Sonification in Theoretical Physics Katharina Vogt Prof. W. Plessas Prof. R. Höldrich Todtmoos, 12th september 2007](https://reader036.vdocument.in/reader036/viewer/2022062515/56649d265503460f949fcf09/html5/thumbnails/14.jpg)
Advantages
+ eyes-free conditions + high temporal and frequency resolution+ parallel audio streams+ the formation of auditory gestalt + backgrounding+ usually interactive
Furthermore in physics:+ many (parameter) dimensions + audio streams as mathematical subspaces+ wave phenomena in nature
![Page 15: Sonification in Theoretical Physics Katharina Vogt Prof. W. Plessas Prof. R. Höldrich Todtmoos, 12th september 2007](https://reader036.vdocument.in/reader036/viewer/2022062515/56649d265503460f949fcf09/html5/thumbnails/15.jpg)
Disadvantages
- low resolution in some variables- potentially the annoyance- no persistence - user limitations and cultural bias- longer history of visualisation- the lack of absolute value and perceptual
orthogonality
![Page 16: Sonification in Theoretical Physics Katharina Vogt Prof. W. Plessas Prof. R. Höldrich Todtmoos, 12th september 2007](https://reader036.vdocument.in/reader036/viewer/2022062515/56649d265503460f949fcf09/html5/thumbnails/16.jpg)
Aims of Sonification
1. Alternative representation of data
2. Use of audition in order to analyse scientific data
3. Artistic application

Sonifications so far
SonEnvir - Sonification Environment (2005-2007)
• Spin models (Ising and Potts model)• Pilot project on topological objects in QCD• Baryon spectra of CQMs• Simple sonifications of the Dirac spectrum• Smaller projects: chaotic double pendulum,
logistic equation

Ising and Potts Model
Ising model:• spin up and down• phase transition
magnetic/ non-magnetic
Potts model:• discrete,• q vectors on unit circle• For q5 1st order phase transition• For q4 continuous€
