Hello Brad,
What I used to do to find noisy poles was tap them with a 7 pound hand sledge
at about 5 or 6 feet up from the ground. If there was loose hardware, a
portable AM radio tuned to a quiet spot would go nuts. Or, in other cases, the
noise would stop.
You don't usually have to hit the pole hard. I did once, and the vibration
travelled down the wires and made a pole several hundred feet away start (or
stop) making noise.
