Beschreibung
This book provides the material for an introductory course in engineering acoustics for students with basic knowledge in mathematics. It is based on extensive teaching experience at the university level. Under the guidance of an academic teacher it is sufficient as the sole textbook for the subject. Each chapter deals with a well defined topic and represents the material for a two-hour lecture. The 15 chapters alternate between more theoretical and more application-oriented concepts. They cover the following issues:
Introduction - Mechanic and acoustic oscillators - Electromechanic and electroacoustic oscillations - Electromechanic and electroacoustic analogies - Electromechanic and electroacoustic transduction - Magnetic-field transducers - Electric-field transducers - The wave equation in fluids - Horn and stepped ducts - Spherical sound sources and line arrays - Piston membranes, diffraction and scattering - Dissipation, reflection and
absorption - Geometric acoustics and diffuse sound fields - Isolation of air- and structure-borne sound - Noise control: a survey - Appendices, e.g, complex notation for sinusoidal signals, power and intensity

This book provides the material for an introductory course in engineering acoustics for students with basic knowledge in mathematics. It is based on extensive teaching experience at the university level. Under the guidance of an academic teacher it is su?cient as the sole te- book for the subject. Each chapter deals with a well de?ned topic and r- resents the material for a two-hour lecture. The chapters alternate between more theoretical and more application-oriented concepts. For the purpose of self-study, the reader is advised to use this text in parallel with further introductory material. Some suggestions to this end are given in Appendix 15. 3. The authors thank Dorea Ruggles for providing substantial stylistic re?- ments. Further thanks go to various colleagues and graduate students who most willingly helped with corrections and proof reading. Nevertheless, the authors assume full responsibility for all contents.

From the reviews:
"Blauert … have prepared a well-written comprehensive book on engineering acoustics, with an emphasis on physical acoustics and electroacoustics. … The figures are very clear. The inclusion of example and practice problems would have been helpful. The book is a welcome addition to the acoustics literature. Summing Up: Recommended. Upper-division undergraduate, graduate, research, and professional collections." (M. G. Prasad, Choice, Vol. 46 (6), February, 2009)
"This is a wonderful book … with 14 useful chapters, each covering a specific topic with the right amount of illustration and a well-guided presentation of the material. … The book is very well structured and it constitutes an excellent study guide for both students and teachers. … a wonderful book that should be considered for the libraries of either teachers or students of acoustics at the college level." (Dominique J. Chéenne, Noise Control Engineering Journal, Vol. 57 (1), 2009)
