static subs still emits noise?

I don't think DW models Akulas going HF, it certainly doesn't make sense from a doctrine standpoint.

Maybe he heard how i clicked switches

He was few km away from me, no more and my silent ambush failed...

Oh, are tubes flooding noise modeled in game? I did that.

IIRC subs do emit noise when static. There were some graphs with noise vs. speed, and all subs, including Kilo, did emit some noise at speed zero. The noise was very small. The noise also did not increase until 5kts or so. Simply speaking static sub makes same noise as slow sub.
No transients like opening tubes are generated by AI subs, nor detected by any sub, AFAIK.

IMHO at 130m you simply detected you. Depends on the background noise. I literally crashed into Kilo once without detecting him, but it was stormy sea.
At 130m he could actually create a shadow on BB by masking background noise. Not that it is simulated in DW.

Your source on this?

It does not. At least if AI is involved on either side. Not sure about player vs. player, as many things are different with player boats.

Just a rumors I'm afraid. But imho it's plausible. Questions is at what range such effect would occur.

I wouldn't expect it to occur due to diffraction except at collision ranges.

130m basically is collisions range.

Maybe for foreign boats.

Still I wouldn't expect 130m to be close enough to cause shadowing of a sonar array.
