I agree with the 1A/B selection. I always try to get those on a 57.

If you get the last row, here are your options. 6A/B is in front of the lav - door opening and closing all the time and the sounds of the flushing toilet.

6C/D also comes with the above, but my favorite is the F/A's who have to chop the ice bags with their mallet throughout the flight. Just when you think it's safe - bang bang bang in back of your head. Very noisy and annoying.

Enjoy.
