“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
Applying sonification techniques to SETI radio astronomy data can be an efficient tool for identifying intelligence patterns
