I agree with you Bubblehead...
Let me put this way: If u are using only 30% of reractor power and your main coolant pumps are on LOW settings and you are creeping at 2 knots you are very,very quiet..If you speed up to 5-7 you will ( im not shure for details,but you will understand) have to increase power outputo to lets say 40%,BUT your coolant pumps will still be able to keep up with heat on LOW.Now if you need to go faster you will at some point switch from LOW to HIGH ( or whatever you call that) and voila: there is sudden increase in noise on certain freq. and that level of noise will stay for lets say up to 20 or so and then will suddenly go even louder..etc..Im talking about reactor equipment only,im not talking about turbines,generators and other aux equipment... Im not an expert but i think there are few of this "thresholds" around.
But if you are going fast and then you order all stop you will not stop at once but radiated nose will be reducet almoust instantly...
