Education: Patricia Davies received her B.Sc. in Mathematics from the University of Bristol in 1977, and her M.Sc. and Ph.D. in Sound and Vibration from the University of Southampton in 1981 and 1985, respectively. Her Ph.D. research was focused on time-domain modeling applied to acoustics and vibrations problems. She stayed at the Institute of Sound and Vibration Research (ISVR) until December 1986 doing postdoctoral research on statistical modeling of shock propagation through structures.
Employment: Between 1977 and 1979 she did voluntary work teaching mathematics in at a Teachers College in Northern Nigeria. She worked at the London Research Station of British Gas in 1980 and 1981, investigating modeling of gas demand based on weather predictions and writing programs to detect faults in pipeline telemetry data. In January 1987 she joined the faculty of Mechanical Engineering at Purdue University working in the Mechanics and the Systems, Measurements and Controls Groups, the latter group she chaired between 1994 and 1998. She returned to ISVR at Southampton to do a sabbatical in 1999. She is currently a Professor of Mechanical Engineering at Purdue and teaches courses in measurements, controls, signal processing and mechanics.
Research Activities: Dr. Davies is a faculty member at the Ray W. Herrick Laboratories, part of the School of Mechanical Engineering, where she conducts research in the areas of: (1) Nonlinear System Identification, (2) Vibration Measurements, (3) Sound Quality and Perception Based Engineering, (4) Acoustical Arrays for Sound Source Visualization, and (5) Event-based Signal Processing. She has applied her research to: modeling the dynamics of the polyurethane foam used in car seats; visualizing automobile noise sources during pass-by tests; predicting reciprocating pump failure; analyzing infant and mother laughter; and modeling human response to refrigerator, HVAC, chiller and large machinery noise. She has co-authored over 80 journal and conference papers. She currently leads a group of engineering and psychology professors who research issues related to perception-based engineering. The mission of this research group is to integrate into the design of engineering systems, the ways in which people perceive and are affected by machinery outputs. Currently her research is funded by Ford Motor Company, Caterpillar, Isuzu and the National Science Foundation. In the past she has also received research funding from the US Army Research Office, GE Appliances, LG Electronics, Whirlpool, Carrier, Vipac, Plymouth Tube Company and Alpine Electronics.
Professional Activities: Dr. Davies is a member of INCE, IEEE, ASEE, SAE and ASA. From 1994-1996, she was the chair of the ASEE Engineering Acoustics and Vibrations Committee. She is the co-chair of an ANSI working group (S12-WG36) on Sound Quality. With Gordon Ebbitt, she organized the technical program for the 1998 and 2002 Sound Quality Symposiums (SQS98 and SQS2002) and helped Richard Lyon organize an International Workshop on Product Sound Quality (PSQ2001+). She is currently a member of the INCE board of directors, and chair of the Perception and Effects of Noise Committee which is part of the Technical Activities Board at INCE.
