On the A380 I thought take off was very smooth. Normally I hear things creaking and shaking but there was none of that on the A380. Possibly as there was no overhead storage bins.
I did think it was noisy when trying to sleep. Someone did tell me that was because I was in economy BEHIND the engines. They said if I was up front of the plane it would of been different. I was up the front. Seat 2 A. I thought the noise of flying was the same as on other aircraft.
