Long years ago, 50 yearsor so before I reached Ham status, a

near I
could hear a loud click as the strike occurred and then the diminishing
rumble. I still haven't figured out the initial click sound, it came
from
outside so wasn't a house internal electric phenomenon.

I've read that this click is due to the ear's reaction to the strong
electromagnetic pulse. If that's what you heard, it comes from the ear
itself, not from outside.

This is the first time I have seen it mentioned the ear reacting to the
electromagnetic pulse. Most of the time it is described as the same way
the old WW2 depth charges sounded in the submarines. YOu get the click and
then the boom. I forgot the term used but it is something like an impulse
or pressure shock wave traveling faster than the speed of sound and then the
actual sound wave.
