auroral hiss  

Définition

  • Electromagnetic hiss is a naturally occurring Extremely Low Frequency/Very Low Frequency electromagnetic wave (i.e., 300 Hz – 10 kHz) that is generated in the plasma of either the Earth's ionosphere or magnetosphere. Its name is derived from its incoherent, structureless spectral properties which, when played through an audio system, sound like white noise (hence the onomatopoetic name, "hiss"). Auroral hiss is observed in the auroral zones of the Earth and can extend up to several hundred kHz. (Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/wiki/Hiss_(electromagnetic))
