The best sonar operators have perfect pitch, except instead of saying "that is an A-flat but there is a ghost harmonic because the slot in the bridge for that string is too wide" they would say "that is a 415 Hz sound with up doppler. sounds like a 3 bladed prop with a notch on the second blade". It was pretty amazing to watch the really good ones in action.
