概述了目前美国宇航局在飞机降噪领域的研究组合。本文所述研究的重点是满足减少飞机噪音排放的积极的近期和中期国家目标，NASA内部研究表明，使用目前正在内部开发或与NASA的工业和学术伙伴合作开发的降噪技术是可行的。虽然NASA在机身降噪方面进行了积极的研究，但本概述仅关注推进降噪。
An overview of the current NASA research portfolio in the area of aircraft noise reduction is presented. The emphasis of the research described herein is on meeting the aggressive near- and mid-term national goals for reducing aircraft noise emissions, which NASA internal studies have shown to be feasible using noise reduction technologies currently being developed in-house or in partnership with NASA’s industry and academic partners. While NASA has an active research effort in airframe noise reduction, this overview focuses on propulsion noise reduction only.
