This three-day course is intended for engineers and other technical personnel
and managers who have a work-related need to understand basic acoustics
concepts and how to measure and analyze sound. This is an introductory course
and participants need not have any prior knowledge of sound or vibration. Each
topic is illustrated by relevant applications, in-class demonstrations, and
worked-out numerical examples. Since the practical uses of acoustics principles
are vast and diverse, participants are encouraged to confer with the instructor
(before, during, and after the course) regarding any work-related concerns.
Dr. Alan D. Stuart, Associate Professor Emeritus of Acoustics, Penn State, has
over forty years experience in the field of sound and vibration. He has degrees in
mechanical engineering, electrical engineering, and engineering acoustics. For
over thirty years he has taught courses on the Fundamentals of Acoustics,
Structural Acoustics, Applied Acoustics, Noise Control Engineering, and Sonar
Engineering on both the graduate and undergraduate levels as well as at
government and industrial organizations throughout the country.
