Definition
Acoustics – The study of sound, including
its production, transmission, and effects. NASA Thesaurus, Washington,
DC: National Aeronautics and Space Administration. Dictionary of Technical
Terms for Aerospace Use. Wm. H. Allen, ed., 1965. NASA SP-7.
NASA Interest
Exhaustive Interest : Acoustic theory, noise
generation, sound attenuation, and related phenomena as they apply to
aerospace equipment and vehicles and their operating environment. For
specific applications see 02 Aerodynamics;
05 Aircraft Design, Testing, and Performance; 07 Aircraft
Propulsion and Power; 15 Launch
Vehicles and Launch Operations; 18 Spacecraft
Design, Testing, and Performance; and 20 Spacecraft
Propulsion and Power.
Selective Interest : Noise generation, sound
attenuation, and other acoustic phenomena related to other means of transportation,
manufacturing, and construction with potential aerospace applications.
Negative Interest : Noise generation, sound
attenuation, and acoustic phenomena with no potential aerospace application.
