This volume examines fish sounds that have a proven signal function, as well as sounds assumed to have evolved for communication purposes. It provides an overview of the mechanisms, evolution and neurobiology behind sound production in fishes, and discusses the role of fish sounds in behavior with a special focus on choice of mate, sex-specific and age-specific signaling. Furthermore, it highlights the ontogenetic development of sound communication and ecoacoustical conditions in fish habitats and the influence of hormones on vocal production and sound detection. Sound Communication in Fishes offers a must-have compendium for lecturers, researchers and students working in the fields of animal communication, fish biology, neurobiology and animal behavior.

The last decades have brought a significant increase in research on acoustic communi cation in animals. Publication of scientific papers on both empirical and theoretical aspects of this topic has greatly increased, and a new journal, Bioacoustics, is entirely devoted to such articles. Coupled with this proliferation of work is a recognition that many of the current issues are best approached with an interdisciplinary perspective, requiring technical and theoretical contributions from a number of areas of inquiry that have traditionally been separated. With the notable exception of a collection edited by Lewis (1983), there have been fewvolumes predominatelyfocused on technical issues in comparative bioacoustics to follow up the earlyworks edited by Lanyon and Tavolga (1960) and Busnel (1963). It was the tremendous growth of expertise c:()ncerning this topic in particular that provided the initial impetus to organize this volume, which attempts to present fundamental information from both theoretical and applied aspects of current bioacoustics research. While a completely comprehensive review would be impractical, this volume offers a basic treatment of a wide variety of topics aimed at providing a conceptual framework within which researchers can address their own questions. Each presentation is designed to be useful to the broadest possible spectrum of researchers, including both those currently working in any of the many and diverse disciplines of bioacoustics, and others that may be new to such studies.

Convergence in Broadcast and Communications Media offers concise and accurate information for engineers and technicians tackling products and systems combining audio, video, data processing and communications. Without adequate fundamental knowledge of the core technologies, products could be flawed or even fail. John Watkinson has provided a definitive professional guide, designed as a standard point of reference for engineers, whether you are from an audio, video, computer or communications background. Without assuming any background and starting from first principles, the four core technologies of image reproduction, sound reproduction, data processing and communications are described. Covering everything from digital fundamentals to conversion methods, sound and image technologies, compression techniques, digital coding principles, storage devices and the latest communications systems, the book shows how these technologies operate together and the necessary conversions that take place between them. Acronyms and buzzwords are introduced only after their purpose has been described in plain English - as the book serves to give a reliable grasp of the fundamentals. The criteria involved in determining image and sound quality are based on a thorough treatment of the human senses, a unique description of how motion portrayal works in managing systems. John Watkinson is an international consultant in audio video and data recording. He is a Fellow of the AES, a member of the British Computer Society and a chartered information systems practitioner. He presents lectures, seminars, conference papers and training courses worldwide and writes for many industry magazines. His other books for Focal Press are widely acknowledged as standard reference works and industry `bibles'. John is author of MPEG2, The Art of Digital Video and the Art of Digital Audio, An Introduction to Digital Video, An Introduction to Digital Audio, The Art of Sound Reproduction, Television Fundamentals, Co-author of The Digital Interface Handbook and Contributor to The Loudspeaker and Headphone Handbook.

book by Stephen Gislason emerged from his Music Notes collected over many years. The topics cover a wide range of interests from the history of instruments, music theory, composing to the most current technologies involved in music composition and sound recording. A special chapter on the Musical Brain explains current knowledge in the brain processing of sound as it applies to language and music decoding. A chapter on the Music Business reviews the dramatic changes in music marketed and discusses some of the dilemmas and controversies facing musicians. Preface This book emerged from notes I have kept for several decades. I have spent much time studying music theory, electronics applied to sound reproduction and to performance skills. I decided to assemble my music notes so that any person interested in music could benefit from simple, clear explanations. Music descriptions often are too complicated and the use of terms can be inconsistent and confusing. As with other subjects I have tackled, I assumed that with a little extra effort more precise descriptions would be welcomed by readers seeking a practical understanding of music. The book begins with a consideration of what sound is and how animals use sounds to communicate. Music is not a human invention, but we do elaborate sound communication more than other animals in our production of both speech and musical performances. The discussion continues with noise, an important topic that is poorly understood. A well informed musician will refrain from making noise and understand Ambrose Bierce when he stated: Of all noise, music is the less offensive." I include acoustic and electronic instruments in my discussions of music creation. In my world, electronics dominate every aspect of work and play and most music I create and listen to was created, stored and distributed electronically. The art and science of recording is an important study for all 21st century musicians. Increased sophistication about the nature of sound, the art of combining musical sounds, and the effect on the listener's brain are all required for music to advance beyond noise toward a more effective means of human communication.
