I think a lot of your discomfort stems from a bad weather day, a bad hair day (for the pilot), and probably sitting aft of the wing. There is no doubt the -200 is one powerfully noisy aeroplane! I once sat in the cabin crew seats right down the back and did not expect that level of noise. I looked across at the 2 stewardesses wondering if we were going to be doing an emergency evacuation, and they were sitting there quite happily sign languaging to each other. I once sat halfway down an AA stretched DC9 thingy, and I couldn't believe the peace and quiet- nowhere in the cabin of a -200 came anywhere near.
