View Full Version : Strange sounds

Is there a sound effect associated with the sub "skimming" the sea bottom, but not necessarily taking damage? I ask because I just completed an infiltration of Manila Bay to photograph some escort carriers that were so far north in the shallows that I eventually bottomed my sub just as I was trying to get out after getting the pictures. I took 10% hull damage and might have damaged my batteries (I still have to get out and back to sea).

I got into the bay easily because it was pouring rain and heavy fog, and I found a place to sit in about 105ft of water near the middle while I waited for the weather to clear. It took two days of submerged days and sitting on the surface at night, with patrols crisscrossing endlessly around me. Finally the third day it cleared and at twilight I surfaced and started off to the objective.

I wove my way around and between multiple DD patrols, usually with two in sight at a time to get to the target. At one point I had one dead on my stern with a zero angle at about 4000yds, I was sure I was cooked. But he didn't see me.

But twice during the ingress I was startled by a sound that was like a large volume of air rushing out of the sub. I couldn't figure out what it was, I figured the first time I was being shot at. But nothing happened and there was no damage.

But just after getting the pictures and turning to the south I had collisions with the bottom. Very frustrating. I was wondering if those previous sounds might have been some kind of warning about the depth being so shallow that the sub could not even draw enough water ahead.

Can't say for sure, lot's of sounds regarding air floating around with all the mods. As far as I know they're no sounds of mass air to warn you of the bottom.

They're are a few sound files that activate based on your depth, mostly more creaks and pops. If you go past crush depth, you'll get a sound sequence of the sub imploding with lots of noise.

As far as air itself, you'll hear some when you rise up and of course if you blow tanks. If you hit bottom, you'll hear a bad grinding sound.

If you hear a sound like canvas tearing, you are being shot at, and if they hit you, there will be plenty of damage.

I know this because this happened to me. I was tracking an enemy ship at night and while down below I heard that sound. It wasn't very loud, and went away quickly, so I went back to the charts. A little later, there it was again. I went up to the bridge where the crew is calmly keeping watch, just in time to see the muzzle flash of the third shell and hear it tearing over us (much louder now). The moral to the story is that you can't depend on the common sense of your crew. :hmph:

I agree with TorpX ... I have had that sort of noise and now I know what it is and dive. Sometimes sounds like a rivet flying threw the air under high speed ... those are a bit further away. Air is pretty quite LOL if you hear it

... dive.

Well it's just hard to describe sound. I definitely know the sound of rounds flying near me, and this was not it. It was a louder, longer, whoosh type sound with a bit of echo and fade. Honestly, not too different from the later sounds when I actually hit bottom and took damage.

Not that this all matters anyway. I had to keep getting closer to get a lock and take the picture. Even if I knew the sound was some type of prelude to grounding I would have had to keep going. Too many escorts around to risk a sonar sounding. Wish I could have sent a guy over the rail with a sounding line.

Not being there, I have no way to be sure, but it sounds a lot like gunfire to me. Remember, if you are inside the sub, the sound will be greatly muffled. It will only be loud once you are outside. It could also be a softer sound if the caliber of the gun is smaller.

You could try opening sound and listening to the files and see if you hear it.

Were you time-compressing prior to this? That can sometimes mess the sound up.
