ever been on an CV? Near the front, during down times you can hear a hissing sound as the water is split by the bow, but if there is ANY deck activity its very hard to hear. Aft, the hissing is a bit louder, and you also can hear a bit of a rumble/chop as the water is churned up in the wake, again if there is any deck activity you hear almost nothing.
It is nothing like the bow of a speed boat slapping against the water as it works to get plained out and on top of the water. Big ships are made to CUT through the water. Its a large mass and anything that can make it slices though better is used so the power can then be used for speed.
What you do hear is activity. Men working, engines running, chains banging around, trucks moving planes and so on. Below decks are rumbles and shudders as well as machinery. There are not too many quite places on a working CV, I know, it was home for 2 years. The whine of the hydraulic pumps for the rudders was my lullaby for all that time, do you know how often they make course correction even on a ship THAT size? About every 3 seconds it seemed like ! LOL!!!
To add a sound to the game CVs would be a continuous loop of "white noise" type stuff. Nothing you could really pick out, just a bunch of "noise".
