I've heard this sound in the past and seen/heard a mercury vapor lamp used
as a yard light produce this sound near a friends house a few years ago.
When the light finally gets "hot" enough, as far as we could tell, it was
winter, it stops flickering and this sound stops.
I've also heard a similar sound from a failing/flashing LED streetlamp,
although not as raspy.
