Speed and Hydrophones

It certainly affects your ability to hear something (not the speed itself, but the engines noise).
I'm not really sure if your SO is also affected.

Your own engine noise will definitely create a deaf-zone to your hydro. to a good amount of angles to the stern of your u-boat. If you are traveling in a known hazardous region, it is best to take periodic moments to stop engines, listen all around, and then get moving.

I think it does affect the SO, cos I tested it once. Ages ago. He got a contact, I told him to track it and then went faster and he lost it, then I slowed down and he re-aquired. It was just the one test - since then I've always had him listen for new contacts on "ahead slow" just in case.

BTW, the contact wasn't in my deaf zone.

That would be nice if it's true. I know AOD did that, with contact lines disappearing at higher submerged speeds. I didn't know SH3 did it. I hope so.

From sensors.cfg:

I reckon "speed factor" might be the speed of the enemy ship (my first guess was "enemy speed" for enemy speed

but that is set to zero suggesting that it does nothing :hmm

so "noise factor" presumably is your own engine noise?

You da man!

The speed of your sub should have no bearing on the hydrophones listening capability/range unfortunately.

For realism I always go to ahead slow or stop
