In my world when we detected an exercise torpedo, we got a bearing, a description, a guess as to closeness, and we immediately followed Torpedo Evasion Protocols depending on relative bearing on which weapon was detected. (Neither me nor anyone else here has ever been on the receiving end of a war shot.)
In the real world, it ain't gonna happen.

Usually, they do not have the time.
Getting a range to a contact is the hardest and most time consuming area of TMA. There are no short cuts........except active, and water conditions are a HUGE factor in that. Some days you can get an active return at 50K. Some days, no return at all, even on a contact at >10K.
Torpedo in the water calls are only generated when the acoustic energy is directed at Own Ship and is of the expected strength.

Yes, I do know getting range is the hardest bit. I do a fair amount of manual TMA in Dangerous Waters, which I know is a video game and not the real thing. Let me clarify what I said: mathematically and theoretically speaking, it's not impossible to get the range of a torpedo, but given what you guys have said, highly improbable in practice.
Or is it mathematically impossible if the torpedo is for all intents and purposes on an intercept track with you and you can't do legs?
