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 book discusses both fundamental and practical aspects of electroacoustic tranducers and arrays used for generating and receiving underwater sound in commercial and naval applications. It provides current information intended to aid those working in this field and teach those entering it. The book describes the six major types of electroacoustic transducers and the latest methods of tranducer analysis and design, including analysis of nonlinear effects and information on modern transducer materials. Many different transducer designs are analyzed and described, including novel designs such as the hybrid transducer. The problems that occur when large numbers of transducers are used together in arrays, such as acoustic interactions in transmitting arrays and noise limitations in receiving arrays, are also discussed in detail.

This book is concerned with the theory, development and design of electroacoustic transducers for underwater applications, and is more comprehensive than any existing book in this field. It includes the basics of the six major types of electroacoustic transducers, with emphasis on the piezoelectric ceramic transducers that are currently most widely used. It presents the basic acoustics, as well as specific acoustic data, needed in transducer design and includes analysis of nonlinear effects in transducers. A large number of specific transducer designs, including both projectors and hydrophones, are described in detail as well as methods of modeling, evaluation and measurement. Analysis of transducer arrays, including the effects of mutual radiation impedance, as well as numerical models for transducers and arrays are also covered. The book contains an extensive Appendix of useful current information, including data on the latest transduction materials, and numerous diagrams that will facilitate its use by students and practicing engineers and scientists.
