Why are Airbus planes so noisy?

The source of certain Airbus planes' characteristic barking noise is a component known as the Power Transfer Unit (PTU). This is an element of the aircraft's hydraulic systems, and it facilitates the switching of power from one system to another in the event of a failure.

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.

1 Airbus A380 The Airbus A380 is the largest commercial passenger aircraft in the world, as well as the quietest widebody airliner currently flying. The A380's double-deck design and advanced noise-cancellation technology make it one of the quietest airliners in the skies.

For most commercial airplanes, the seats closest to the front of the plane are the quietest. And although it's not always possible to get a front row seat, anything in front of the wing is preferable to seating behind the wing. The loudest row is just behind the wing where the engines are located.

Takeoff: Two quick, loud thumps from under the plane, and a repeated whooshing noise that sounds like a spinning propeller. The whooshing noise is air from the engines (the air used for the cooling and heating system) changing as the RPM of the engine increases.

During the day, when the air is warmer than the ground, noise energy from an airplane staying in the air, so while you can still hear it, it seems quieter. Conversely, at night, when the ground is warmer than the air, the noise is drawn down, making it seem louder.

If being packed in a plane with lots of other people gives you anxiety you are not alone. So many travelers struggle with this fear, so the best way to cope is to find a seat with plenty of space. The least crowded section of the plane is first or business class.

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.

In the longer term, after 2050, completely new aircraft geometries that use blended wing designs, and even aircraft that change shape will potentially lead to major reductions in airframe noise, greater efficiency and improved environmental impact.”

Over the past 50 years, aircraft have reduced their noise output by 75% and this progress continues. Today's aircraft entering service have on average, a noise footprint that is 30-50% that of the aircraft they are replacing thanks to new engine and airframe design and technology.
