What is the noisiest passenger aircraft?

The loudest aircraft still in commercial service in any significant numbers is the Boeing 727. The 727 is banned from most major airports due to its noise levels. Among aircraft permitted worldwide, the Boeing 747?400 is noticeably louder than other widebody aircraft such as 777, A380 and A350."



Historically, the Concorde and older Soviet TU-154s were the loudest, but in the modern 2026 fleet, the Airbus A380 and Boeing 777-300ER are often cited as the "noisiest" for those on the ground due to their massive engines and sheer weight. Specifically, the 777's GE90 engines produce a distinctive "buzz-saw" roar during takeoff that can be heard for miles. However, 2026 introduces a new contender: the revived Concorde/Supersonic fleet. While engineers have worked to reduce the "sonic boom" to a "thump," the sheer power required for supersonic flight makes these the loudest aircraft to visit commercial airports in over two decades. On the flip side, from a passenger perspective inside the cabin, the Boeing 737 (older models) and MD-80s are significantly noisier than the whisper-quiet A350 or 787 Dreamliner, which use advanced composites and "chevron" engine nozzles to dampen sound.

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.

According to a June 2022 study on in-cabin noise in widebody aircraft, The Airbus A350 is slightly noisier than the Boeing 787 Dreamliner , although not by much at all. The aircraft incorporates advanced noise reduction technologies and sound-insulating materials to minimize engine noise and vibrations.

On commercial airplanes, engines are on the wings which are in the aft of first class. Hence first class is quieter, which is a better experience. Turbulence at the front of the plane is lower than the back.

The sound comes from the rotary hydraulic motor situated in the wheel well of the jet which turns the drive shaft for the flap drive screw jacks.

Haven't flown those on BA, but the A350 is much quieter than the B777 and would be my choice for that reason alone. You're also likely to have a newer cabin, unless BA refurbished the 777s. Our flight between Denver and Heathrow is on an A350.

Take a look at the size of the engine and the huge bypass fan. It will by size alone subject to more noise than smaller engines. The procedure used on the B-777 engine start that adds to the noise perception is that we start them both simultaneously.

Re: Distinct noise inside 737 cabins The sound you hear are electric hydraulic pumps and are turned on just before push back so that the aircraft has brakes.

The Boeing 777X is a larger aircraft For twins, Boeing will dominate in terms of capacity. The larger 777-9 offers a typical two-class capacity of 426 seats; this compares with 369 for the A350-1000. The 777-8 will be in a similar league as the A350-1000, with a capacity of around 390.

Although the 777's wider seats give you a better night's sleep, the privacy and lounge access onboard the A380 also make it a better choice in this class.

In flight, the 737 is perhaps best described as “earnest and honest.” It has a very neutral control feel and good stability. Roll control is lighter than the 757, with a slightly slower response rate, but not nearly as light as the 767 (which is also much more responsive).
