Book SynopsisThis textbook provides materials for an introductory course in Engineering Acoustics for students with a basic knowledge of mathematics. The contents are based on extensive teaching experience at the graduate level. Each of the 14 main chapters deals with a well-defined topic and represents the material for a two-hour lecture. The chapters alternate between more theoretical and more application-oriented concepts. The presentation is organized to be suitable for self-study as well.For this third edition, the complete text and many figures have been revised. Several current amendments take account of advancements in the field. Further, a completely new chapter has been added which presents approaches and solutions to all assigned exercise problems. The new chapter offers the opportunity to explore the underlying theoretical background in more detail. However, the study of the problems and their proposed solutions is no prerequisite for comprehending the material presented in the book's lecture part.Trade Review“The book is systematic but concise, covering the acoustic basics required for engineering applications, as well as electroacoustic transducers, room acoustics, noise control, and more aspects of the fundamentals. … it is also beneficial to engineers and technicians engaged in the development of related technologies, so it is hereby recommended.” (ACTA ACUSTICA, Vol. 48 (4), 2023)“As its title suggests, the book takes a structured, engineering approach. … It also serves as a reference book to delve deeper into individual topics or to revisit buried knowledge. … Acoustics for Engineers is convincing in its brevity and structure and is consequently recommended to all readers who, in addition to a well-illustrated presentation of the fundamentals of acoustics and electro-acoustics, are interested in their derivations, correlations, and analogies, as well as in the calculation of typical problems.” (Martin Schneider, vdt Magazin, Issue (2), 2022)Table of ContentsIntroduction.- Mechanic and Acoustic Oscillations.- Electromechanic and Electroacoustic Analogies.- Electromechanic and Electroacoustic Transduction.- Magnetic-Field Transducers.- Electric-Field Transducers.- The Wave Equation in Fluids.- Horns and Stepped Ducts.- Spherical Waves, Harmonics, and Line Arrays.- Piston Membranes, Diffraction and Scattering.- Dissipation, Reflection, Refraction, and Absorption.- Geometric Acoustics and Diffuse Sound Fields.- Insulation of Air- and Structure-Borne Sound.- Noise Control – A Survey.- Solutions to the Exercise Problems.- Appendices.

Book SynopsisThe limiting influence of the environment on sonar has long been recognised as a major challenge to science and technology. As the area of interest shifts towards the lit­ toral, environmental influences become dominant both in time and space. The manyfold challenges encompass prediction, measurement, assessment and adaptive responses to maximize the effectiveness of systems. Although MCM and ASW activities are dom­ inated in different ways and scales by the environment, both warfare areas have had to consider the significantly changing requirements posed by operations in the littoraL The fundamental scientific issues involved in developing models relating acoustics to the environment are matched in difficulty by the need for data for their validation and eventual practical use for prediction. In many instances the need is for on-line adaptation of systems to changing circumstances whilst other needs are for the Ionger term planning activities. This book and the attached full-color CD are the proceedings of a conference organ­ ised by the SACLANT Undersea Research Centre, held at Villa Marigola, Lerici, Italy, on 16-20 September 2002. The fundamental problems associated with environmental 1 variability and sonar were explored at a previous SACLANTCEN conference in 1990. These problems have not gone away but, on the one hand are exaggerated by the move to the littoral and on the other hand, are open to treatrnent in new ways that advances in technology and computer power allow.Table of ContentsPreface.

Book SynopsisWaves are essential phenomena in most scientific and engineering disciplines, such as electromagnetism and optics, and different mechanics including fluid, solid, structural, quantum, etc. They appear in linear and nonlinear systems. Some can be observed directly and others are not. The features of the waves are usually described by solutions to either linear or nonlinear partial differential equations, which are fundamental to the students and researchers.Generic equations, describing wave and pulse propagation in linear and nonlinear systems, are introduced and analyzed as initial/boundary value problems. These systems cover the general properties of non-dispersive and dispersive, uniform and non-uniform, with/without dissipations. Methods of analyses are introduced and illustrated with analytical solutions. Wave-wave and wave-particle interactions ascribed to the nonlinearity of media (such as plasma) are discussed in the final chapter.This interdisciplinary textbook is essential reading for anyone in above mentioned disciplines. It was prepared to provide students with an understanding of waves and methods of solving wave propagation problems. The presentation is self-contained and should be read without difficulty by those who have adequate preparation in classic mechanics. The selection of topics and the focus given to each provide essential materials for a lecturer to cover the bases in a linear/nonlinear wave course.

Book SynopsisThis book is the first volume of the bioacoustics series published by the Society for Bioacoustics. This volume provides an overview of the advances and recent topics in acoustic communication in various animals. Most animals produce vibrations and sounds by moving their body parts, including vocal organs. These sounds can be research targets of bioacoustics studies. How animals use these sounds, especially in inter-individual relationships, is the focus of this volume, “Acoustic Communication in Animals”. The authors’ expertise varies from molecular biology, neurobiology to psychology, and human brain imaging. Their research subjects range from invertebrates to humans. Despite the variety of topics, chapters are developed under the consideration of ethology and evolution. Readers will recognize the profundity of the topics in each chapter. In addition, the view and understanding of natural sound sequences produced by animals can vary among different cultures. Research from Japan and regions that have been underrepresented in previous literature can offer new ideas and unique perspectives in the study of bioacoustics. Readers can grasp the progress of this research field in a broad range of species in one book. The book presents multi- and interdisciplinary topics and appeals to researchers and students in fields including psychology, physiology, zoology, ethology, and neurosciences.Table of ContentsChapter 1.
