Flight tests at NASA Glenn demonstrated that serrations on the engine exhaust nozzle could reduce noise.

Making the most of acoustical research at NASA Glenn
Reducing noise produced by aircraft engines has been our primary mission. What we’ve learned in the course of our studies, however, can often be useful for solving other acoustical problems—be they here on Earth or in space.

We’ve provided breakthrough technology to quiet fans, jets, and propellers which have been the dominant sources of aircraft engine noise. We’re after ways to make these components run more quietly without sacrificing system performance or efficiency.
