I’ve flown on it as well, and the quietness is really remarkable.
While all other passenger planes are smaller than the A380, it’s also far quieter than other very large passenger planes like the 747 and 777. Other modern designs making significant use of composites like the A350 and 787 are also not nearly so quiet.




They’re only about 10-15% more powerful. The 777 has far larger and more powerful engines, but only two of them.
