Why The Airbus A350 Has Such A Quiet Cabin Compared To Other Aircraft

Early jet-powered airliners were characterized by extremely loud and high-pitched noises. People are reminded of these noisy aircraft whenever they appear in older movies, but, if you go to an airport today, those classic jet noises are largely absent. There is no loud noise from the engines as they idle or taxi, and the noise during takeoff is more of a deep roar than a high-pitched scream.
