On the electrophonic generation of audio frequency sound by meteors
Geophysical Research Letters, 2017 Recorded for centuries, people can hear and see meteors nearly concurrently. Electromagnetic energy clearly propagates at the speed of light and converts to sound (called electrophonics) when coupled to metals.

A Reference Meteor Magnitude for Intercomparable Fluxes
The Astronomical JournalThe rate at which meteors pass through Earth’s atmosphere has been measured or estimated many times over; existing flux measurements span at least 12 astronomical magnitudes, or roughly five decades in mass.
