Exhibition „Invisible Geographies“
Electric power supply voltages and frequencies differ all around the world and their emitted electromagentic fields can be captured as sounds with electromagnetic headphones. The common supply voltage in Europe is 230V and the frequency 50Hz. In comparison, the voltage and frequency in New York is 120V and 60Hz, respectively.
Due to this difference in supply voltages the fundamental electromagnetic “hum” sounds different in New York than in Europe and the city’s electromagnetic waves of neon tubes, subway trains, light advertisements and LED tickers created an overall deeper and warmer sounding electromagnetic landscape.
