HaHa erik. It was only once and I was in a field of tall cedar brush out near Dugway. It was a very bright bolide that lit up the the sky like a full moon. It was very unnerving and sent me to the internet for information. The NASA website, if you bother to read it, points out that these sounds have been reported throughout history and were dismissed as imaginary by none other than Edmund Halley. But the science explanation is only recent but is still solid.

It was his tin foil hat.
Interesting article. Daniel, do you hear meteors often, or was your
experience singular? If you hear them often, do you have an idea what the transducer might be? Brent

Guess it depends on how close you are.

It turns out meteors make a lot of low frequency radio noise which travels at near light speed. Then common objects in the vicinity of the listener act as transducers that turn the vlf signial to an audio signal. Frizzy hair, pine needles, leaves, grass. I have experienced this and can vouch for it. It was a low and slow Leonid that passed over head and made a noise like a sizzling steak on the grill with absolutely no time delay or dopler shift. Just a rise and fall of the volume with the brightness of the meteor. DT
