Dynamic noise values?

[SchDerGrosse]

Since the recent patch the game shows the noise values generated by ships (in DBs).

Judging by the fact that this is the default setting, I would assume that this is somehow useful information.

Thus the question, how do you actually use this piece of data? I dont need DB values to know that my sub is noisier if it is going fast and quituer if it is just creeping forward.

Are there some actual gameplay decision one can make based on seeing the exact amount of noise the ships are generating?

Thanks,
