Elektrosluch is an open-source device for electromagnetic listening. It allows one to discover the sonic worlds of electromagnetic fields, surrounding our every step. At the end of this project you will have a working version of Elektrosluch, ready for your headphones to be plugged in. Consequently you will be able to listen to the electromagnetic fields of the various devices around you. My suggestions for starting out are to place the Elektrosluch near computers, tablets, cellphones, cameras, and CD players, to listen to the unique sounds of their electromagnetic fields.
