Trama

This textbook provides graduate and advanced undergraduate students with a comprehensive introduction to the application of basic principles and concepts for physical and engineering acoustics. Many of the chapters are independent, and all build from introductory to more sophisticated material. Written by a well-known textbook author with 39 years of experience performing research, teaching, and mentoring in the field, it is specially designed to provide maximum support for learning.  Derivations are rigorous and logical, with thorough explanations of operations that are not obvious. Many of the derivations and examples have not previously appeared in print. Important concepts are discussed for their physical implications and implementation. Many of the 56 examples are mini case studies that address systems students will find to be interesting and motivating for continued study. The example solutions address both the significance of the example and the reasoning underlying the formulation. Tasks that require computational work are fully explained. This volume contains 168 homework exercises, accompanied by a detailed solutions manual for instructors. Building on the foundation provided in Volume I: Fundamentals, this text offers a knowledge base that will enable the reader to begin undertaking research and to work in the core areas of acoustics.

Autore

Jerry H. Ginsberg’s technical education began at the Bronx High School of Science, from which he graduated in 1961. This was followed by a B.S.C.E. degree in 1965 from the Cooper Union, and an E.Sc.D. degree in engineering mechanics from Columbia University in 1970, where he held Guggenheim and NASA Fellowships. From 1969 to 1973 he was an Assistant Professor in the School of Aeronautics, Astronautics, and Engineering Science at Purdue University. He then transferred to Purdue's School of Mechanical Engineering, where he was promoted to Associate Professor in 1974. In the 1975-1976 academic year, he was a Fulbright-Hayes Advanced Research Fellow at the École Nationale Supérieure d'Électricité et de Mécanique in Nancy, France. He came to Georgia Tech in 1980 as a Professor in the School of Mechanical Engineering, which awarded him the George W. Woodruff Chair in 1989. He retired in June 2008. His prior publications include five textbooks in statics, dynamics, and vibrations, most in several editions, as well as more than one hundred twenty refereed papers covering these subjects. Dr. Ginsberg became a Fellow of the Acoustical Society of America in 1987, and a Fellow of the American Society of Mechanical Engineers in 1989. The awards and recognitions he has received include Georgia Tech Professor of the Year (1994), ASEE Archie Higdon Distinguished Educator in Mechanics (1998), ASA Trent-Crede Medal (2005), ASME Per Bruel Gold Medal in Noise Control and Acoustics (2007), and the ASA Rossing Prize in Acoustics Education (2010). In addition to his technical activities, he is an exceptional photographer.
