About Spectronics

Spectronics, Inc., was established in 1988 as an outgrowth of the research in vibro-acoustics at the University of Kentucky, USA. Spectronics is fundamentally a technology development and sales company. Our primary goal has always been to concentrate on only those areas that we are expert in.

Our business model includes three primary areas. The first is the development, manufacturing, and sales of robust, high-end impedance tubes for the measurement of sound absorption in the laboratory and in situ. This activity includes the highly successful ACUPRO system and the newer ACUPAVE system for in situ testing. Second, Spectronics has pioneered the use of numerical methods in vibro-acoustics, and this work continues today in the use of boundary element, finite element, and statistical energy analysis software for the solution of engineering problems. Third, Spectronics has developed a strong set of measurement skills for industrial, product, and environmental noise analysis.

Spectronics’ founder and president, Andy Seybert, remains active and involved in every aspect of the business: research, engineering, applications, and support. Today, as in 1988, you can be sure that any question or problem you have will be addressed with the attention that you would devote to it yourself.

Andy Seybert is currently on phased retirement from the University of Kentucky where he has been a professor since 1977. This appointment allows him to be fully engaged in the day-to-day activities of Spectronics, while allowing him to continue research at the University of Kentucky. Andy has a BS degree from the University of Cincinnati and the MS and Ph.D. degrees from Purdue University, all in mechanical engineering. He is a fellow of the Acoustical Society of America, the American Society of Mechanical Engineers, and the International Institute of Acoustics and Vibration. At Purdue, Andy was affiliated with the Ray W. Herrick Laboratory where he conducted research in vibro-acoustics of engines, HVAC systems, and other product lines. At the University of Kentucky, Andy has built a research program that is internationally known for its work in both experimental methods and in numerical acoustics.

Andy, along with David Ross, were both graduate students when they published their landmark 1977 paper in the Journal of the Acoustical Society of America showing that random excitation and a pair of microphones could decompose a plane wave field in an impedance tube, including the determination of the impedance of the termination. This work led to the development of ISO and ASTM standards for the measurement of sound absorption.

In the late 1980’s Andy had the benefit of working with outstanding colleagues including David Shippy and Frank Rizzo in the application of the boundary element method to acoustics. This work continued for many years with the participation of a number of outstanding graduate students and other faculty members.

In 1996 at the urging of several former graduate students, Andy organized the University of Kentucky Vibro-Acoustics Consortium, a network of companies interested in the use of advanced vibro-acoustic methods, both computational and experimental, for the solution of NVH problems. The VAC continues today at the University of Kentucky with approximately 15 industrial partners.
