I live in the suburbs of Phoenix.
At night, when there's no traffic on the roads,
I can hear the fire station doors opening and the
trucks starting. They are right at 3/4 mile away
from me.

Any time of the day, I can hear the F-16/F-15s
landing and esp taking off at KSDL which is
three miles away. They refuel there on weekends
when the Air Force is closed. That noise is loud
enough to make it hard to talk on the phone, not
just faint and "hear it if you listen hard enough".
And that's talking on the phone inside the house.
My house is concrete block construction.

I can hear horses and burros at least three miles
away in our subdivision.

My hearing is horrible. I have a lot of high
freq loss in both ears, and extremely bad in
my right ear.

So for people with good ears, in an area with
very little ambient noise, I would certainly
expect something as monsterous as a jet engine
to carry many, many miles indeed.
