Shallow water evasion

The noise meter is not a definitive science but more an indicator that you are making noise and may be heard

This is something I've come to understand, but in the scenario I just described, I was essentially surfaced with the bridge watch on duty, yet was undetected by the DD until after I submerged, all other factors remained the same in that I did not change engine settings, or go silent running. The fact is that I was probably making more noise on the surface than submerged due to the diesle engines, so why did the DD not detect me sound wise until I went down?

Also, I want to point out that the meter really shows you how likely you are to be detected by enemies. It will stay green if you are surfaced next to a neutral, and go red if you are within an enemie's visual range (though they won't necessarily detect you), even at a dead stop with silent running in force. At least that has been my observation.
