Hi,
For years, eversince the first Boeing 777-200 aircraft came out we have been hearing about newer "quieter" aircraft and the Boeing 777 did deliver as it was way quieter than the old Airbus A340-200/300, however, Airbus answered back with the quieter Airbus A340-500/600 series. I know that today's aircraft are scignificantly quieter than aircraft of 20 years ago. However, there has been a lot of speculation that both Boeing and Airbus might leave out a lot of sound insulation because of the quieter GEnx and Rolls Royce engines, which would essentially reduce the benefit of the quieter engines. However, both Boeing and Airbus claim that less sound insulation will reduce aircraft weight and increase both fuel efficiency and range.
I know that these planes, the Boeing 747-8, 787, and Airbus A350, have many noise reducing features like the swoping wings, the chevrons on the Boeing engines, better acustic liners on the front of the engines, etc. Nevertheless, with the reduced sound insulation on these aircraft I have doubts on whether they will be supper quiet or just a little bit quieter than today's aircraft.
What are your guys' thoughts?
