Quieting the Skies
Engineers in the Acoustics Branch at NASA Glenn know that noise isn’t just a nuisance. Cities need vibrant airports to enable local businesses to thrive, to join the global marketplace, and to draw the world to their doorstep. But as airport traffic increases, cities are faced with tough choices pitting the health and quality of life of thousands of residents living near airports against the greater good of their region’s economy.

Imagine what it would be like if we could keep aircraft noise at the airport.

That’s exactly what we have in mind at NASA Glenn. Rather than finding ways to live with noise, we’re conducting the research needed to understand the underlying physics that enables engineers to develop quieter airplanes.
