Some details of the electrophonic phenomenon you can find here:

The sound is produced by vibrations of some objects close to the
observer and these vibrations are induced by very low frequency (VLF) and
extremely low frequency (ELF) radio waves (30Hz - 30kHz).
The open question about this phenomenon is how the meteors can produce such
a strong ELF/VLF radio emission, since the current Colin Keay's theory:

has problems with some electrophonic fireballs.
