electromagnetisms – 14 simple interactions with electronic devices
sound piece for radio (2017)
a coil within an alternating magnetic field makes the conversion of mechanical vibration into electric activitiy possible. therefore one of its applications is found in the production of microphones and speakers as it allows the fetching and generating of sound waves. the coil is also used as one of the main elements of radio receivers, and with all the other elements makes the fetching of radio signals possible. radio technology functions on the principle of transimitting and receiving inaudible electromagnetic waves. these signals are shifted into the hearing range through processes such as the demodulation of the signal and they become the content of the radio programme.
”i was fascinated by the above mentioned simple facts so i made my own pickup coil – a kind of a mirophone that picks up electromagnetic emmisions of electronic devices. since radio receivers are usually callibrated to filter out this sort of intereferentions from the signal i thought it would be interesting to play these sounds on a radio programme. i recorded electromagnetic emmisions of fourteen electronic devices that i use on a regular basis and made them audible. my goal was to make these unwanted sounds wanted, prefering the noise to signal. with this approach i reduce the radio to its most basic elements, and the radio broadcast is taken literally – as an electromagnetic wave. the composition itself was made as a set of spoken instructions of use for each device. i followed the instructions and recorded the devices simultaneously.”
can we learn something about our relationship with electronic devices by listening to their electromagnetic emmisions?
