I played around with it just now. That is because you are increasing speed. Above 12 knots the bow sonar suffers from flow noise. Above 8 knots the hull array suffers from flow noise. Seems pretty normal to me. (for a fictitious platform)
It's much like riding a bicycle down hill. You may be going fast, and are fairly quiet compared to cars around you. But the rushing of the wind around your ears makes you quite deaf. Speed always comes at a price.
