So, as a disclaimer, I fly very often and average about 130,000 miles a year. I also work in the airline industry and know quite a bit about these beasts I fly on. That being said, I'm pretty tuned into the "sounds" that airplanes make throughout the different phases of flight especially the A320 which seems to be the aircraft I fly the most.
Yesterday, I was on UA519 from PHX to SFO on N339UA- a TED configured A320 now in UA mainline paint:

So just after we lifted off there was a fairly high pitched sound and a distinct vibration which kept getting louder and stronger. The noise and vibration dissipated for a little while and then started even stronger than before as soon as we started to bank to the right. The vibration was really remarkable especially during this turn and then seemed to get less and less the higher we went. It was so remarkable that it was louder than the sound of the engines (which I was sitting next to in 6A) and the vibration was so distinct that it was almost hard to see clearly.
I was listening to Channel 9 the whole time and nothing was mentioned and the crew carried on as completely normal so I knew that this was probably no big deal (actually, Thank Goodness for Channel 9 because I'm sure my anxiety level would have gone through the roof!) but I was wondering if anyone has experienced this before or if any of you have any insight as to what the heck this was.
Some of my thoughts as to what was going on was perhaps an open panel (i.e. cargo door control panel or maybe the ground power panel) or something wrong with the engine- but obviously that was not the case.
Anyway, any insight would be greatly appreciated!
