The Airbus A330neo has a smaller noise footprint.
Peace and quiet. The low noise footprint of its engines makes it the most silent aircraft in its category!
In fact, the noise level in the aircraft is 3dB lower than the Boeing 787.
The exterior noise footprint is also reduced thanks to the construction materials chosen for this aircraft and its brand newgeneration of Rolls-Royce Trent 7000 engines.
