The most comprehensive book on electroacoustic transducers and arrays for underwater sound Includes transducer modeling techniques and transducer designs that are currently in use Includes discussion and analysis of array interaction and nonlinear effects in transducers Contains extensive data in figures and tables needed in transducer and array design Written at a level that will be useful to students as well as to practicing engineers and scientists

This improved and updated second edition covers the theory, development, and design of electro-acoustic transducers for underwater applications. This highly regarded text discusses the basics of piezoelectric and magnetostrictive transducers that are currently being used as well as promising new designs. It presents the basic acoustics as well as the specific acoustics data needed in transducer design and evaluation. A broad range of designs of projectors and hydrophones are described in detail along with methods of modeling, evaluation, and measurement. Analysis of projector and hydrophone transducer arrays, including the effects of mutual radiation impedance and numerical models for elements and arrays, are also covered. The book includes new advances in transducer design and transducer materials and has been completely reorganized to be suitable for use as a textbook, as well as a reference or handbook. The new edition contains corrections to the first edition, end-of-chapter exercises, and solutions to selected exercises. Each chapter includes a short introduction, end-of-chapter summary, and an extensive reference list offering the reader more detailed information and historical context. A glossary of key terms is also included at the end.

Underwater Electroacoustic Transducers is a practical handbook for users and designers of underwater transducers. This book continues to be a primary authoritative text in the field since first published by the Bath University Press in 1991. It is now more than 25 years since the original edition of this book was written and much work, aimed at new applications and the development and use of new materials, has been carried out since that time. Indeed, while the fundamental principles of underwater transducer design have remained unchanged in those subsequent years and, hence, the main body of the book remains as before, a new Chapter 13 was added to reflect the considerable work on the development and use of piezoelectric single crystals that has transpired. Further, Chapter 12 (New Materials and Concepts) was also updated to inform us of the research on the development and use of lead-free materials in response to the increased interest in reducing the use of lead in the environment. The main body of this book addresses underwater transducer design methods. They are discussed and illustrated by concentrating on the design of piezoelectric transducers in the 2 - 20 kHz range, most commonly used in today's sonar systems. Design of sonar transducers at lower frequencies is also discussed. Treatment is down-to-earth and avoids complex mathematics. For the user: the book discusses the main features of the various types of transducer designs, identifies the important requirements, and assists in the drawing up of realistic specifications. For the designer: the book details the theoretical and practical aspects in developing your design to most effectively suit the application and the requirements specified by the user.

Part of a series which is aimed primarily at a professional engineering or postgraduate student audience, this book concerns the basics of the propagation of sound in the sea, the problems of waveform analysis, underwater acoustic equipment and underwater acoustic communication.
