Noise

Limiting aircraft noise during the takeoff and landing phases facilitates the responsible development of air transport. Safran designs systems and equipment that help reduce the noise generated by aircraft.

At Safran, we have long focused on reducing aircraft noise, which primarily impacts people living near airports. For instance, since the end of the 1990s, aircraft noise has been cut in half. And the noise footprint of each new generation of aircraft is estimated to be at least 15% lower than the previous generation.

Current research into noise reduction focuses on both engines and aircraft systems, such as landing gear.
