The hearing organs of non-mammals, which show quite large and systematic differences to each other and to those of mammals, provide an invaluable basis for comparisons of structure and function. By taking advantage of the vast diversity of possible study organisms provided by the "library" that is biological diversity, it is possible to learn how complex functions are realized in the inner ear through the evolution of specific structural, cellular and molecular configurations. Insights from Comparative Hearing Research brings together some of the most exciting comparative research on hearing and shows how this work has profoundly impacted our understanding of hearing in all vertebrates.

The Springer Handbook of Auditory Research presents a series of comprehen sive and synthetic reviews of the fundamental topics in modern auditory research. The volumes are aimed at all individuals with interests in hearing research including advanced graduate students, postdoctoral researchers, and clinical investigators. The volumes are intended to introduce new investi gators to important aspects of hearing science and to help established inves tigators to better understand the fundamental theories and data in fields of hearing that they may not normally follow closely. Each volume is intended to present a particular topic comprehensively, and each chapter will serve as a synthetic overview and guide to the lit erature. As such, the chapters present neither exhaustive data reviews nor original research that has not yet appeared in peer-reviewed journals. The volumes focus on topics that have developed a solid data and conceptual foundation rather than on those for which a literature is only beginning to develop. New research areas will be covered on a timely basis in the series as they begin to mature. Each volume in the series consists of five to eight substantial chapters on a particular topic. In some cases, the topics will be ones of traditional interest for which there is a substantial body of data and theory, such as auditory neuroanatomy (Vol. 1) and neurophysiology (Vol. 2). Other volumes in the series will deal with topics which have begun to mature more recently, such as development, plasticity, and computational models of neural processing.

Perspectives on Auditory Research celebrates the last two decades of the Springer Handbook in Auditory Research. Contributions from the leading experts in the field examine the progress made in auditory research over the past twenty years, as well as the major questions for the future.

This volume focuses on the history of research on hearing from comparative approaches. Each chapters examines the most formative studies that led to current understanding of hearing across taxa and still influence hearing research in general. Much of the early work on hearing, which goes back to Aristotle, as well as the classic work of 16th to early 20th century scientists (e.g., Spellanzani, Retzius, Ramón y Cajal, and Helmholtz) is not well known to modern investigators. Similarly, work in the first 75 years of the 20th century is also unknown or, in some cases, dismissed because it is “old.” Much of the earlier work describes research approaches and results fundamental to our understanding of hearing as well as the beauty of observation and synthesis. The pioneering work on hearing contains ideas and questions that are still germane today. Thus, the goal of this volume is to introduce, review, and put into perspective, older but exemplary, extraordinary studies by investigators that form the basis of our knowledge as well as questions being asked today. Each chapter includes the first significant observations and approaches to hearing in the taxa and/or hearing type that is the focus of the chapter with some of the most important earlier papers discussed in some detail, including the theories, formative experiments, results, and conclusions. Each chapter provides briefer notations and citations of additional important papers that are outgrowths of the founding research – or correlate and even reverse the original works. This volume is a departure from the classic approach established for the SHAR books in which the focus has been on a single topic, and on the most recent and exciting discoveries. One difference in this volume from past SHAR volumes is that we have a more coordinated approach for the chapters to ensure that this volume is, indeed, a documentation of hearing research history, not a review of the latest status of the topic. A second difference is that the focus of the volume is on the historical value of studies. In that sense, the volume maintains the tutorial value for which SHAR books are famous, but it explores the ancestry of modern research in order to help new researchers to gain perspective on important questions and on fundamental information they may not fully appreciate – to their loss. Our interest in doing this volume comes from phenomena familiar to most senior investigators - that younger investigators often have little or no sense of the history of their discipline, and they often do not know that their “hot” new idea was not only pursued, and often solved, but further that it was solved in an elegant way. We believe it is important to bring the methodologies and discoveries on hearing done before the advent of the internet to light, for the benefit and growth of new research. In deciding on the chapter divisions for this book, we considered a number of different organizational schemes, and particularly using as a focus methodological approaches (e.g., psychoacoustics, low to high frequency types, physiology, anatomy). However, we came to the conclusion that most investigators tend to be more focused on working within a particular taxonomic group, settling on particular taxa, in many cases driven by the special hearing abilities. We also concluded that that this approach is more naturally related to the evolution not only of hearing, but also to the evolution of ideas, as much of hearing science was part of the “natural philosopher” approach that was a core element of historical discoveries.

Experimental approaches to auditory research make use of validated animal models to determine what can be generalized from one species to another. This volume brings together our current understanding of the auditory systems of fish and amphibians. To address broader comparative issues, this book treats both fish and amphibians together, to overcome the differing theoretical and experimental paradigms that underlie most work on these groups.
