Noise-induced hearing loss is caused by a sound\u2019s power, as well as the amount of time it is heard \u2014 an occupational hazard for military pilots. Brian Thurow, W. Allen and Martha Reed associate professor, is working to reduce this risk along with researchers from the University of Mississippi\u2019s National Center for Physical Acoustics, the University of Texas and Combustion Research and Flow Technology Inc. The team has been awarded a collaborative $1 million grant by the Office of Naval Research Jet Noise Reduction Program (ONR-JNR), which funds research that explores jet noise to address pilot health and safety issues, as well as technology that can increase stealth capabilities for military jets. Thurow\u2019s work includes taking high speed flow visualization measurements of up to a million frames per second in a supersonic jet facility at the National Center of Physical Acoustics. He will also use near and far field microphone array measurements to study the aeroacoustics of heated shock-containing jets and computational modeling of air flows to reduce jet noise.<\/p>\n
