Richard H. Lyon - (Chair)
RH Lyon Corp.
Richard Lyon’s interests are within the fields of sound, vibration, and machine and structural dynamics. Most recently, he has worked in the engineering and psychoacoustical aspects of product sound, relating the desired aspects of the sound to the design of mechanical components and structure. The psychoacoustical part of this involves experimental design, testing methods, and data analysis. The engineering part involves dynamical analysis and simulation, experimental studies, and computation.
A second area is the transmission of acoustical energy within complex structures and to the surrounding fluid. I developed the method of Statistical Energy Analysis (SEA) that treats vibratory energy as a form of thermal energy and takes advantage of this similarity to find simple relationships that help one predict and interpret the spatial distribution of the energy within a structure and the surrounding fluid. In recent years, this effort has been extended to an analysis of the phase of vibratory signals, called Statistical Phase Analysis (SPA), which has application to machine diagnostics and signal de-reverberation in telephony and other areas.
Lyon has also been active in developing new ways to analyze acoustic signals from machinery to diagnose events that are not readily handled by conventional methods. These involve highly transient vibrations that occur in reciprocating machinery due to impacts and transient forces among the components. This effort has required the application of certain signal processing techniques that, while known, had not been widely used for the purposes of machine diagnostics.
Krish K. Ahuja
Georgia Tech Research Institute
Dr. Ahuja has more than 25 years of research and development experience in noise research, acoustics facilities design, acoustic propagation, flow control, state-of-the-art instrumentation, advanced signal processing, and wave phenomenon in general. During his 13-year tenure with 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 or 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 and Professor of Aerospace Engineering in March 1989. His current research interests include innovative sensors for flow, acoustics, and seismic measurements, community noise, jet noise, acoustic liners, design of quiet wind tunnels and engine test cells, flow control, thermoacoustics, automobile noise, effect of noise on sleep, and innovative application of acoustics to the consumer market. While at Georgia Tech, he received the GTRI's 1990 Outstanding Performance in Research Award and the Georgia Tech-wide "Outstanding Interdisciplinary Activity Award" for 1991. In 1993, he received the prestigious AIAA Aeroacoustics Award. The American Institute of Aeronautics and Astronautics named him Engineer of the Year for 2000. He is an AIAA Fellow as well as a GTRI Fellow. Dr. Ahuja is a former associate editor of the AIAA Journal and a former Chairman of the AIAA Aeroacoustics Technical Committee. He holds a number of patents in the field of acoustics, including one on a sensor to reduce background flow noise, one on quiet curtains, one on rapid charging of batteries by sound, and another on a high-temperature acoustic liner that uses sound-absorbing beads. Dr. Ahuja teaches graduate level classes at Georgia Tech in Aeroacoustics and Rocket Propulsion. He is also the manager of the Aerospace and Acoustics Technologies Branch in the Aerospace, Transportation, and Advanced System Laboratory. Dr. Ahuja has authored or coauthored more than 100 publications. He has appeared in Congressional hearings on noise and has taken part in a number of peer reviews of national programs in acoustics.
Paul R. Donovan
Illingworth & Rodkin, Inc.
Paul Donavan received his master and doctorate of science degrees in Mechanical Engineering and Acoustics from the Massachusetts Institute of Technology in 1976. He began his professional career in environmental noise working in the Washington D.C. area at Wyle Laboratories and then at the National Bureau of Standards. In 1979, he moved to Michigan to work at General Motors— initially doing tire/pavement noise research. In his 20 years at the GM Noise and Vibration Laboratory, Donovan led vehicle noise control activities in the areas of tire, aerodynamic, and passby noise, and structureborne noise analysis. Since 2001, he has been at the acoustical consulting firm of Illingworth & Rodkin, Inc., in Petaluma, California, where he continues his work in tire/pavement noise and more general environmental noise.
He has been a member of the Acoustical Society of America since 1973 and is currently a member of the Noise Technical Committee. Paul is also a member of the Noise and Vibration Committee of the Society of Automotive Engineers. He served as president of INCE/USA in 2001. He is currently president-elect, and will serve again as INCE/USA president in 2006. Paul is also currently the I-INCE Vice-President Pan-America, and serves as Pan-American Editor for this magazine.

Mr. Tocci is a registered Professional Engineer in the Commonwealth of Massachusetts and the State of Rhode Island. He is a Fellow of the Acoustical Society of America, a past president of the National Council of Acoustical Consultants, President of the Institute of Noise Control Engineering, and Associate Editor of the Noise Control Engineering Journal.
Richard F. Topping
RF Topping Consultants, LLC
Mr. Topping is launching R.F. Topping Consultants, LLC after a distinguished career as Vice President and Director of Arthur D. Little, Inc., and more recently as a Director of TIAX LLC. Mr. Topping concentrated his efforts at these technology development and consulting groups on the appliance, energy and HVAC Industries. He was responsible for managing internal intellectual property development for ADL's Technology and Innovation business with the goal of developing significant non-traditional revenues for the firm.
Through multiple activities as a leader of multidisciplinary design teams, Mr. Topping has experience in coordinating the development of products throughout the design, testing, prototyping and pilot production for the field testing of new energy saving equipment. Leadership responsibilities investigating automation for natural gas pipelines and other industries has provided experience in assessment of technology, defining cross-cutting concepts, and identifying technological and R&D gaps in the desired field of application.
Mr. Topping's early career exposure to gas turbine engine technologies provides excellent connections to other areas being considered by the subcommittee.
