Paolo L. Gatti is an independent vibration consultant with a degree in nuclear physics and has thirty years of experience in engineering vibrations, non-destructive testing and statistical data analysis.
I would recommend this book to those who would want to understand the math behind the principles and equations used in vibrations. It is logically presented and very comprehensive at a high level in describing the mathematics of vibrations. It also could be helpful as a supplemental text in a high-level engineering graduate course on mechanical vibrations. James K. Thompson, Institute of Noise Control Engineering of the USA
