You should probably start with Colin Keay for reliable information on this

Abstract
Anomalous sounds from large meteor fireballs, anomalous because they
are audible simultaneously with the sighting, have been a matter for
debate for over two centuries. Only a minority of observers perceive
them. Ten years ago a viable physical explanation was developed (Keay,
1980) which accounts for the phenomenon in terms of ELF/VLF radiation
from the fireball plasma being transduced into acoustic waves whenever
appropriate objects happen to be in the vicinity of an observer. This
explanation has now been verified observationally and supported by
other evidence including the study of meteor fireball light curves
reported here.
