Electromagnetic Spectrum
Listen to the waves
VLF
"On appelle très basse fréquence (VLF), Very low frequency en anglais, la bande de radiofréquences qui s'étend de 3 à 30 kHz (longueur d'onde de 100 à 10 km). Les ondes VLF sont aussi appelées ondes myriamétriques." wikipedia
"L'ionosphère est l’atmosphère supérieure d’une planète, en référence à son état de conductibilité électrique qui est caractérisé par une ionisation partielle des gaz. L’ionosphère terrestre comprend trois régions neutres, à savoir la mésosphère, la thermosphère et l’exosphère." Wikipedia

Se fabriquer une antenne et un récepteur pour écouter les VLF
Il est tout à fait possible de construire une antenne et d'amplifier le signal reçu avec la carte son d'un ordinateur, il faudra filtrer le 50Hz du courant électrique 220v !
