Acoustics Research

Our vision is to help increase the peace and quiet in the world by serving as a leader in aircraft engine noise reduction research

Our Mission

We envision, experiment, assess, model, and predict aeroacoustics mechanisms to provide noise reduction tools and technologies for the benefit of all.

Engineers and scientists conduct experimental and analytical research to reduce aircraft community noise and partners works with industry, academia, and other government agencies to fulfill this mission. Capabilities are maintained to develop and apply diagnostic tools for acoustics, as well as aerodynamics, to predict noise and analyze propulsion systems. Research is performed in small facilities, such as our Acoustical Testing Lab, as well as larger world-class test facilities including the Aero-Acoustic Propulsion Lab and the 9-foot by 15-foot low speed acoustic wind tunnel (LSWT).

Technical Focus Areas: Subsonic Aircraft, Supersonic Aircraft, Advanced Air Mobility (AAM), and Electrified/Hybrid Aircraft Propulsion.

Cities need vibrant airports to enable local businesses to thrive, to join the global marketplace, and to draw the world to their doorstep. As airport traffic increases, cities are faced with difficult choices, the health, and quality of life of residents living near airports against the greater good of their region’s economy.

Aircraft noise is a barrier to emerging aviation markets.

Rather than finding ways to live with the noise, we’re conducting the research needed to understand the underlying physics that enables engineers to develop quieter airplanes.
