Electrophonic sounds from meteors and auroral audibility

TL;DR

This paper explores the phenomenon of electrophonic sounds caused by meteors and auroras, proposing that meteoroids trigger processes generating sounds, with new evidence supporting this idea and focusing on auroral sounds for better understanding.

Contribution

The paper introduces a novel hypothesis that meteoroids trigger processes causing electrophonic sounds, supported by new arguments and focusing on auroral sounds to deepen understanding.

Findings

Electrophonic sounds are caused by processes triggered by meteoroids.

Auroral sounds may provide insights into electrophonic phenomena.

New evidence supports the trigger hypothesis over energy transfer explanations.

Abstract

Electrophonic sounds from meteors are sounds simultaneous with meteors (i.e. without delay). They are known for hundreds years. At least several hypotheses were put forward, but none of them received confirmation. Most hypotheses consider the energy of the meteoroid as a source of sound energy. In the early 1990s the author published several articles with another idea - a meteoroid is just a trigger of some processes which cause (in favourable geophysical conditions) electrophonic sounds. In this paper new arguments in favor of this idea are presented. Much attention is paid to sounds of aurora, which (in the author's opinion) could help better understand electrophonic sounds from meteors.
