National Aeronautics and Space Administration (NASA). This Technical Standard approved by NASA 01.20, 2011. Superseding NASA-STD-7001. 39 p. The term vibroacoustics is defined as an environment induced by high-intensity acoustic noise associated with various segments of the flight profile. Vibroacoustics manifests itself throughout the payload in the form of transmitted acoustic excitation and as structure-borne random vibration. This Standard specifically addresses the acoustic and random vibration environments and test levels.
