PICTURE: Airbus tests noise-reducing technology on A340-600 development aircraft

Airbus's A340-600 development aircraft (F-WWCA) is flight testing technology to reduce noise inside airliner cabins.

The trial, dubbed "LINFaN" (low interior noise fan nozzle), is a collaborative programme that Airbus is undertaking with Rolls-Royce.

Airbus, which is leading the study, says it is part of "ongoing research and technology test work to further reduce noise inside the aircraft cabin".
