The composition “Definierte Lastbedingung” (engl. defined load condition) is based upon the sound of electromagnetic fields as they arise when using electric devices. Numerous recordings of electromagnetic fields were made at the Institute for Electrical Machines, Traction and Drives (IMAB) of Technical University of Braunschweig with a special microphone.
This sound material has little of what a “musical” sound is intrinsically. There is no depth and no momentum. In their noisiness these sounds are static, though moved inside. They usually seem bulky, harsh and repellent, even hermetic as the well known electrical hum.
“Defined load condition” (a technical term when testing electrical machines) works with these sounds which are studied in their structure, reformed and musically dramatized by the means of the electronic studio.
The mains frequency of electrical current in Europe is 50 hertz and 50 and its multiples is also the numerical key this composition is based upon in a variety of ways.
