Grain to KM

[Fister]

Hi there,

is there a factor to convert Grain into KM or SM?

Thx

Maybe you want to elaborate what grain means to you? I've only heard o grain in context to ammunition weight and when talking about seeds, and these can't be converted to a length.

Thought with grain u can determine how far away a ship is.

Umrechnen kann man nur wenn man schon einen Wert hat. Du weisst noch nicht einmal was du mit grain meinst und willst dann diese nicht vorhandene Information in km umrechnen? Wie soll das denn gehen?

Think MrFirster meant "Gain". X-D

I usually set the gain level to a value where I can just hear a little distortion.
(High pass at 1, low pass at 8)

With these values I find it very easy to get a very precise bearing on the target.
For a rough estimation of distance im meters, I usually multiply the gain level by 2000.
Works best for gain levels between 3 to 4.

There are many other factors to consider though.
Like I said, very rough but not completely off. ^^

Gain into KM: Gain x 1,2 x 1,86 = km to target.
Easy as that, I dunno why people always start a fuss about topics like this, just answer the question.

So its roughly a factor of ~2,2.
Will try this next time I go on "Feindfahrt". :)
Like I said, I use this only for a rough estimation.

In my opinion it is just more rewarding to estimate the course and the distance of the convoy by the "four bearing methode".

in reality the intensity is inversely proportional to the square of the distance from the source
(Inverse-square law)
it means exponential and not linear sound reduction.

But maybe not in this game (should check the source code )
whatever,i just barely tested in game
and here the result:
with High pass,low pass at 22 and max volume
the noise of the propellers is saturate at :
2km with gain2
6km with gain3
10km with gain4
16km with gain5
20km with gain6
25km with gain7
31km with gain8
36km with gain9
41km with gain10

So: ( gain_level − 2 ) × 5 = km distance
