The aircraft incorporates advanced noise reduction technologies and sound-insulating materials to minimize engine noise and vibrations. The result is an overall remarkably quiet cabin environment.

While both aircraft have much quieter cabins than their competitors, the A350 definitely feels a lot quieter than the 787, no matter which part of the plane you're sitting in. The A350 is in fact the quietest twin-engined aircraft in the skies. The only plane quieter is it's double-deckered older brother, the A380.

However, generally, the larger the plane, the better it is at absorbing turbulence. For example, due to the sheer size, aircraft like the Airbus A380 and Boeing 747 are said to be two of the best planes for coping with turbulence.

Airbus claims the A350 is five decibels quieter than competing aircraft [the Boeing 787], and up to nine decibels quieter towards the front of the cabin. This means four times less noise. This, of course, is without Airbus actually releasing their data.

Range and flexibility. Surprisingly, for all its size, the A380 can't go as far as the A350. The A350-1000 can travel more than 1,000 km (540 NM) further than the A380. Singapore Airlines has a special 'ultra-long-range' (ULR) A350-900, which operates on the longest route in the world, from Singapore to New York JFK.
