Active & Passive Sonar in SHV

So...
1. Combined sound from convoys should travel longer... checked.
2. DDs should have realistic number of DC... checked.
3. Depth charges should hinder passive detection... checked.

But what about hiding inside a convoy and using wrecks as a sound screen? Ok I know that the sub has a specific noise that can be picked up even if it overlaps the sound of a merchant, but each knot of speed is important when dodging DDs and I doubt that any sound man could pick up a 2/3d's running sub on top of a flank running (and panicked) merchant.
