Yep! What Armistead said!

What really makes it interesting, is when you get the balao boat, and keeping her trim below 600ft. You can run silent, but you will start to sink deeper and will need to figure out what speed at depths passed 600 will keep you levelled off. It is easier to lose the dds at greater depths, but it's a tradeoff, because you have to run at slightly higher speeds, which makes more noise. The upside, is that it takes longer for ashcans to get down to your depth, so you can usually outrun them at more moderate speeds, preserving battery power.

Just give yourself some more time to get used to it again. And if need-be, until you find out what works, use the external view, F12 to see what's going on. Without 3D sound, it's hard to figure out exactly where the dds are coming at you from, where if you had sounds reflecting the position of the charging escort, you could make the appropiate turning manuevers.
