Research Areas and Descriptors
Background
Dr. Cunegare began at Tech in 1990 as an Assistant Professor. Prior he was an F.V. Hunt Postdoctural Fellow at The Technical University of Berlin.
Research
Dr. Cunefare's research is directed toward controlling and tailoring the sound produced by engineered structures, such as from transformers, motors, and in aircraft and automobile interiors. He has investigated the means to better model the acoustic radiation from such structures, and how sound and vibration propagate through these structures. He has developed design optimization methods to permit tailoring of the acoustic characteristics of structures by integrating commercially available modeling codes. This optimization might be used, for example, to design and reduce interior noise levels within aircraft cabins by optimally distributing the mass and stiffness of the material in the fuselage. Dr. Cunefare has also investigated how active control might be used to tailor acoustic responses. In active control, secondary powered actuators are used to suppress or cancel the sound produced by some other source, such as from an engine exhaust.
Dr. Cunefare's interests are not restricted to noise control; he also has an interest in architectural acoustics and in bio-acoustics. He is collaborating with Drs. Christopher Lynch and Robert Guldberg of the Woodruff School to see if acoustic emission, the sound an object makes as it is stressed, might be used as a diagnostic tool to detect osteoporosis. Dr. Cunefare recently constructed the Integrated Acoustics Laboratory, a state-of-the-art facility funded by the Ford Motor Company, the National Science Foundation, and Georgia Tech. This facility is intended to provide educational and research opportunities that span the theoretical, computational, and experimental range of acoustics.
