TheAurora Borealis , also known as the northern lightness , is a dramatic meteorological consequence produced by the charged particles from the Sun hitting the upper atm . anecdotical stories intimate that some of these events can make weird sounds , and reflexion in the last few years not only found such sounds but also memorialize them . Now , investigator think that they have an account for them .

As report in enquiry presented last year at the EUROREGIO / BNAM2022 Joint Acoustics Conference , the auroral sounds are a lot more common and they do happen even without a visible aurora . recording of these auditory sensation that can assume various manikin , like applause or body of water fall , have shown an challenging inter-group communication with the geomagnetic natural process of the planet .

“ Using the geomagnetic data , which was measured independently , it ’s possible to auspicate when aurorean sounds will happen in my transcription with 90 percent accuracy , ” lead author Professor Emeritus Unto K. Laine of Aalto University , say in astatement .

Laine ’s explanation derive fromprevious work on this subjectlinking the sounds to very specific conditions . Favorable atmospheric condition is necessary because the audio come out to amount from theTemperatureInversion Layer , the warm melodic line country located above the Earth’s surface ’s dusty melodic line . Warm atmosphere prove and throughout the 24-hour interval lifts ions , electrically charged atoms . The sounds are the electric discharges materialize in this layer .

The daybreak is a distinct phenomenon that announces geomagnetic disturbances – but it is not the only one , so auroral sounds can mold even when the aurora is not present .

“ That was the magnanimous surprisal ! The strait are much more vulgar than anyone think , but when people find out them without seeable aurora , they think it ’s just deoxyephedrine fracture or peradventure a cad or some other animal , ” Laine proceed .

Hundreds of phone were record at night in the village of Fiskars , Finland , in January last class . Among them , 60 were select for the statistical comparison .

“ This cancel the argument that auroral sound are extremely rare and that the aurora borealis should be exceptionally bright and snappy , ” Laine explained .

A potential early written mention of these sounds come in from the Bible . The prophet Ezekiel dialogue of a phenomenon that has been interpreted asan unusually low latitude northern light . The biblical prophet mentionedthe roaring of many piss .
