This port is pretty quiet all the way through. About 0.400 lift you can hear the faint 'train coming' rumble of separation starting. It never does get loud but there is some bouncing of the manometer at 0.600-0.650.
At this point I think I need to look at the shape of my short turn, especially in the corners. The center of the short turn is not that tricky. The corners are a different story. Lots of options there.
