    Dr. Donavan began his professional career in acoustics in 1976. At General Motors from 1979 to 2001, Dr. Donavan led projects and group activities in tire/road noise, interior noise control, aerodynamic noise generation, and exterior vehicle passby noise. Prior to 1979, he worked at Wyle Labs and the National Bureau of Standards on issues of environmental noise and noise measurement. Although Dr. Donavan has a broad background in acoustics, his particular areas of expertise include tire noise, sound intensity methods, aeroacoustics and wind tunnel testing, and structure-borne sound analysis. He received his Doctor of Science degree from the Massachusetts Institute of Technology specializing in Acoustics with research in urban sound propagation. Dr. Donavan has authored numerous technical papers and given short courses in his areas of expertise. In 2001, he served as President of the Institute of Noise Control Engineers (INCE-USA), and was recently appointed Secretary General of the International Institute of Noise Control Engineers (I-INCE).
