Before I flew on the A380 for the first time, I've always heard that the inside cabin is extremely quiet you wouldn't notice the plane has taken off. Last year in December, I took a trip from HKG-SYD on the A380. I was sitting in the forward section of the upperdeck but did not notice the cabin to be any quieter than other aircrafts like the 777. So can anyone who have more experience on the A380 where the plane is really more quiet than any other aircrafts?
