I think perhaps what is being got at, is the reasons for the sound being made? where the vulcans tradmark “howl” when accelerating on takeoff, is caused by air resonating with the intakes, and the blue note on the hunters, being caused by resonation with the gun ports, the canberra makes her noise for a different reason? just my opinion 🙂

i can certainly hear some howling that sounds fairly unique here, is this what you are getting at SB?
