Recenzje

" Jerry H. Ginsberg offers what will surely become a quintessential 'graduate-level' acoustical text. ... There is something for everyone in Acoustics: A Textbook for Engineers and Physicists whether they are in architectural acoustics, underwater acoustics, psychological and physiological acoustics, or electroacoustics. Ginsberg has created the "ultimate" graduate-level textbook in acoustics." (Brandon Cudequest, Journal of the Audio Engineering Society, Vol. 66 (3), March, 2018)

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.

This graduate and advanced undergraduate textbook systematically addresses all core topics in physical and engineering acoustics. 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. Presentation begins from a foundation that does not assume prior study of acoustics and advanced mathematics. Derivations are rigorous, thoroughly explained, and often innovative. Important concepts are discussed for their physical implications and their implementation. Many of the examples are mini case studies that address systems students will find to be interesting and motivating for continued study. Step-by-step explanations accompany example solutions. They address both the significance of the example and the strategy for approaching it. Wherever techniques arise that might be unfamiliar to the reader, they are explained in full. Volume I contains 186 homework exercises, accompanied by a detailed solutions manual for instructors. This text, along with its companion, Volume II: Applications, provides a knowledge base that will enable the reader to begin undertaking research and to work in core areas of acoustics.

• Provides broad and comprehensive treatment of the basic principles and phenomena encountered in physical and engineering acoustics
  
• Approaches derivations and examples in a logical, lucid, and rigorous manner, with special attention given to the reasons behind the formulation, and detailed explanation of operations that might be unfamiliar to the student
  
• Contains 64 innovative examples, some based on real-world systems, which highlight the connection between physical phenomena and derived principles
  
• Embeds coverage of numerical methods into the examples, including discussion of algorithms and associated macrocode, with Matlab code available online
