Biography

Dr. Ahuja has over 30 years of research and development experience in aircraft noise research, acoustics facilities design, flow control, state-of-the-art instrumentation, and advanced signal processing.  During his employment of 13 years at Lockheed Georgia Company in various capacities, including the head of the Aeroacoustics Research and acting manager of the Advanced Flight Sciences Department, he was the principal investigator and/or the program manager on several successfully completed projects funded by Lockheed, the U.  S. Air Force and NASA.  He joined the faculty of Georgia Institute of Technology as a Senior Faculty Research Leader in March 1989.  His current research interests are:  jet noise, design of quiet wind tunnels and engine test cells, flow control, thermoacoustics, advanced acoustic liners, community noise, automobile noise, effect of noise on sleep, infrasonics, airframe noise, and innovative application of acoustics to consumer market.   Dr. Ahuja is a former associate editor of the AIAA Journal and also a former Chairman of the AIAA Aeroacoustics Technical Committee. Dr. Ahuja has published over 100 articles in the field of noise.
