Sunete "electrofonice"?

[Guest]

Am gasit un paragraf interesant pe site-ul societatii americane de meteori care aparent face referire la un sunet produs de meteori care se percepe in acelasi timp cu observatia vizuala - deci se propaga cu viteza luminii. Aparent sunetul este perceptibil cand stam langa obiecte metalice dar si parul de pe cap are un rol important in perceperea acestui sunet. Aparent sunetele nu sunt validate stiintific desi presupun ca fenomenul nu este chiar unul unic... Teoretic acele radiatii ar fi trebuit sa fie identificate pana acum, insa originea lor este considerata necunoscuta. Teoria populara ar fi ca sunt emisii radio de frecvente foarte joase insa ipoteza nu a fost verificata.

Another form of sound frequently reported with bright fireballs is "electrophonic" sound, which occurs coincidentally with the visible fireball. The reported sounds range from hissing static, to sizzling, to popping sounds. Often, the witness of such sounds is located near some metal object when the fireball occurs. Additionally, those with a large amount of hair seem to have a better chance of hearing these sounds. Electrophonic sounds have never been validated scientifically, and their origin is unknown. Currently, the most popular theory is the potential emission of VLF radio waves by the fireball, although this has yet to be verified.

Nu am gasit termenul electrofonic in dex, poate are alta traducere in limba romana.

Este vorba de efectul fotoacustic descoperit de părintele telefonului.
