 “The transformation of data relations into perceived relations in an acoustic signal for the purposes of facilitating communication or interpretation” (Kramer et al, 1999).

 Everyday Examples  “Ping” of microwave oven  Play video games without sound  Geiger counter  Scientific applications  Seismology  ECG analysis  DNA Sequencing  Geographical Information Systems  Helicopter engine telemetry analysis  Higgs Boson simulation

 The ear is better at detecting rapid or transient changes than the eye.  We perceive several sounds simultaneously  An “eyes free” interface  We don’t have ear-lids  Back grounding  But also…  Sound can be irritating!  Hearing impediments/amusia  ( Kramer 1994)

 Can sonification can speed up the analysis/exploration of very large scale data sets?  Labour intensive with visualization methods  The “Data deluge” caused by modern astronomical observations  An ideal candidate is The Search for Extra- Terrestrial Intelligence - SETI

N = R f p n e f l f i f c L N = number of advanced technological civilisations R = number of new stars formed each year f p = fraction of stars with planets n e = Number of planets that can support life f l = fraction of planets which have life f i = fraction of planets where life is intelligent f c = fraction of planets where life has developed ability to communicate over stellar distances L = average lifetime of technological civilisation (SETI League, 2003) It is estimated that there could be 100,000,000 intelligent civilisations within the Milky Way
