Sound Communications

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.

Since the first edition was published seventeen years ago social and technical changes have altered the world of acoustic communication. This book draws upon many traditional disciplines that deal with specific aspects of sound, and presents material within an interdisciplinary framework. It establishes a model for understanding all acoustic and aural experiences both in their traditional forms and as they have been radically altered in the 20th century, Digital technology has completely redefined the listening and consumption patterns of sound. We are now able to benefit from the march of technology via a companion CD-ROM, which accompanies this volume for the first time.

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.
