Data sonificatie is a way to listen to changes in data time series of any kind. The output of a sensor (temperature, seismic, gamma, EM waves etc) is often in mV/mA and can be amplified. This can be converted into music. It can be done with existing digital data or analog data in real time. Long time series can be compressed which makes it possible to hear the unseen....

This example is from an ELF (extreme low frequency EM waves) receiver, in which the inductive EM respons of our planet to the effect of solarwind and lightning is turned into "music". Enjoy listening!
