i used the sh3 editor to find out by measuring off distance for a t-3 tanker with the measuring tool from the center of the u-boat. i started at 17 km, heard it, so then moved the t-3 out to 25km, heard it again as the mission started so i kept moving it out until i couldnt hear it as the mission started. that turned out to be 34km.
i made this mission to go along the the other mission for the sound trainer, the objective would be to calculate range by the amplitude of the screws in the hydrophones. the captain in the sound trainor would be updated to range of the t-3 by radio messages, so that he could with practice be able to estimate range to target just by how loud the screws are.
the mission also shows you how to build a sonar overlay on the map, 10 concentric circles of 3.4km apart . this visually lets you see your listening range , and also for sound plotting. the mission starts out with the t-3 at 34.96km from the u-boat, you begin to hear it 3 minutes after the mission starts. at that moment , when the t-3 enters your listening range, you know the t-3 is 34km from you. the t-3 has a turncount, you take one and now you know what speed its making. now its easy to plot on the sonar overlay its progression to you.

You are absolutely right. I did this test myself and could hear very faint from 34km.
Have you tried what distance you can hear a convoy? Should be much further away.
What I have read, realistic values for german subamrine hydrophones was a spottingrange of 20km for single ships and up to 100km for a convoy. Then weather and seacontitions had influence.
I'll open a new thread about how to alter this in the modforum.
Would like to have the following settings:
1. Sonarman react on a contact when I myself can hear it. Not like it's now with this huge difference
2. Have possibility to alter detecting range so single ships can be detected at maximum 20km and convoys at maximum 100km.
Hope its possible. Will perform some tests with detecting range for large convoys
