Information about own submarine noise and diving depth

[Qosmius]

Do anyone have information about the us submarines ingame? Such as your own decibel value and how deep you can dive?

[r4y30n]

It's all in the vessel files, self noise and test depth. Crush depth is a variable range.

[Wraith_Magus]

Test depth is indicated by where the "passing XXX feet" turns red. Crush depth would realistically be different on different individual submarines depending on the exact quality of their build, and it's modified by taking damage, but is more static in this game.

The Los Angeles's test Depth is 1000 feet (which is why it's the bottom of the guage), and you can get down to 1500 feet before crushing at full hull %. According to the files, it has a 115 db sound.

The Sturgeon can go a bit deeper, with test depth being 1320 feet. Crush depth is something like 1800-2100 feet. 130 db.

Narwhal is similar to the Sturgeon, but with a 105 db sound profile.

The Skipjack, meanwhile, has a 700 foot test depth (crush around 1100 feet), and a sound profile of 140 dbs.

You know when you have gone too deep as there is no longer a sub on the 3D view .... just a load of hull plates flying around

Where do you find the vessel files? im kinda new to the game.

Find your game folder. Easiest way to do this is to right-click Cold Waters in your library -> "Properties" -> "Local Files" tab -> "Browse Local Files..." button. From there, ColdWaters\ColdWaters_Data\StreamingAssets\default\vessels\usn_ssn_*.txt. (With * as the name of the ship class.)

so the dbs level you listed is with the sub running at which speed setting all stop, 1/3, 2/3. standard, full or flank?

[Qosmius]

i would guess its silent running or full stop. machine that weights several tons should be making more than 120 decibels when engines go at max

Good one...

Don't be a troll and not help.

The noise ratings listed in descriptions are the sub's BASE rating as entered in the vessel files. This is before any modifiers are applied (All Stop @ 0knots, if you are drifting you are still producing extra noise). Speed will increase your noise by 1db per knot.

I am unaware of how noise is added for cavatation (I'm guessing it multplies your speed in knots noise by a valve but unsure), running pumps when flooding, repairing and reloading your tubes. I am also guessing that running creep/silent mode will allow you to move at 5knot speed with your base noise rating

[Qosmius]

You actually are a bit more silent if you have full stop on your engines comparing to run 5kts with silent running, i testet it out yesterday.

... er, I just was wondering the same thing/question than @CloudyDOSH ... I'm not very aware of modern terminology, social networks and all that stuff (I do not use them) but my gess is that troll means I did 'something bad'... I apologize if I broke some rule :-(

On the other hand, this:

was the answer to that question... very useful!

But still, It would be great knowing at any time a measure of our own ship radiating noise somewhere printed, se we caould compare it with ambient noise and have an idea of how exactly noisy we are.
Specially if we can, from 1.07 onwards select a certain knot speed...

[Aldodrem]

SORRY. I thought you meant by putting good one... that you thought it was a dumb question.

And I guess with Qosmius test we now know that silent running reduces your base noise value but not by 5. So making up a value for a sub here but asumming your base is 100db we know the following

Silent Running @0 Knots = < 100db
@0 Knots = 100db
Silent Running @5 Knots = >100db but <105db
5 Knots = 105db
10 Knots = 110db
etc.

We just need to know the actaul value assigned to silient running now as well as tube loads, pumps running if flooded, repair work & cavitation.

This is all very useful information. Maybe make a Guide on this forum when you have put all the information together?

[Hurric]

Are these decible levels for real .... 100db and upwards for a submarine, thats really loud

look at these db levels

[The Inept European]

They are probably using a different reference point for dB than the normal one used for noise pollution. dB are always set vs some reference point. There isn't such a thing as an absolute dB measure of anything really.
