This video segment explains how NASA's Quiet Aircraft Technology Program is helping to improve the environment in and around airports. Viewers learn that much of an airplane's noise comes from air turbulence and that modifications to the engines, wing flaps and landing gear are reducing the noise effects significantly. The video also discusses how scientists perform such acoustical research to minimize sound propagation. The video includes an interview with an acoustical scientist.
