The 777 produces a much smaller noise footprint than the A340
Noise footprints show how much noise a community is exposed to when an airplane takes off. The smaller the footprint, the better for airport neighbors. The 777's more aerodynamic landing gear and twin engines are just two of the improvements that we've made in noise performance. As a result, the 777 is quieter than the competition -- and the 777-200 is the quietest airplane in its class. Reducing noise is just one of the ways that we minimize the environmental impact of our airplanes. We know that quiet airplanes make for happier airport neighbors.
The 777 is quieter than current and proposed noise standards
Our goal is safe, efficient, affordable airplanes with excellent environmental performance. And our 777 airplanes are so remarkably quiet that they meet tomorrow's international noise standards today. The cumulative margin of the 777-300 is as much as 20 decibels below the current Chapter 3 international stands, and the cumulative margin of the 777-200 is as much as 25 decibels below the standard. At Boeing, we believe airplanes should be seen, not heard.
