Yes, it's possible, but it's not guaranteed. If you launch a spread of torpedos, have a target to track, several escorts to monitor, can you listen to all of them at once? Will you be able to detect that one erratic fish, out of the salvo? The game attack map handles this issue in the usual gamey way, by giving you error-free, best case info every time.
