The Dome of Silence
Join the NASA Glenn Research Center for a tour of the Aero-Acoustic Propulsion Laboratory, and see where some of the world's most advanced aircraft noise-reduction ideas are developed and tested.
Unique in size and appearance, this world-class facility stands 65-feet high and 130 feet in diameter. It has 17,000 two-foot-thick fiberglass wedges mounted on its walls and floor. Designed to prevent echoes and reverberations, the wedges give the facility a futuristic, maze-like appearance.
Don't miss your chance to come inside and see how Glenn engineers are reducing ground noise around airports and cabin noise on airplanes.
