With chapters from audiology professionals from around the world, Advances in Audiology and Hearing Science presented in two volumes-provides an abundance of information on the latest technological and procedural advances in this ever-improving field. Volume 1 primarily focuses on revised clinical protocols and provides information on new research to help guide decisions and criteria regarding diagnosis, management, and treatment of hearing-related issues. Topics include new clinical applications such as auditory steady-state response, wideband acoustic immittance, otoacoustic emissions, frequency following response, noise exposure, genomics and hearing loss, and more. The volume also includes a section on canine audiology, allowing students and professionals a broader exposure to hearing science.

The tremendous amount of work that goes into the diagnosis and subsequent management of a young child with a permanent sensori-neural hearing loss involves both professionals from health and education services and parents. Though it is now widely accepted by professionals that parents should be regarded as full members of the team supporting the hearing-impaired child, many still do not have a clear idea of what this means in practice. The purpose of this book is to share information about this work among all those involved. Written by professionals who have long experience of working in real co-operation with parents and who allow the voice of parents to come through clearly, the book has two main aims. First, to convey in a clear and readable way what professionals do, the language they use, what influences their decision-making and some of the ramifications of hearing impairment; and, secondly, to convey to professionals what it is like to discover that your child has a hearing impairment and to show what professionals can learn from parents about the experience of living twenty-four hours a day with a child who does not hear well.

Common forms of preventable hearing loss are drug and noise-induced hearing loss which are believed to be produced by a similar mechanism. The generation of reactive oxygen species appears to be a common mechanism mediating hearing loss produced by these different sources. As such, a number of laboratories have focused their research towards identifying the sources of ROS production in the cochlea following administration of chemotherapeutic agents or noise exposure. This led to the identification of ROS generating enzymes, such as xanthine oxidases, nitric oxide synthase, and NADPH oxidases which are activated and/or induced during the development of hearing loss. A consequence of these findings was the implementation of antioxidants in preclinical studies for the treatment of hearing loss. These antioxidants have provided different levels of protection in animal and human studies, but none of these have been approved by the US Food and Drug Administration for the treatment of hearing loss. More recently, it was shown that noise-induced hearing loss was associated with recruitment of inflammatory cells and mediators in the cochlea. This finding would suggest that noise could produce injury to the cochlea which stimulates local and/or circulating inflammatory cells. A similar finding was observed in the cochlea following administration of the anticancer drug, cisplatin. In addition, our laboratory and others have provided a plausible mechanism by which noise or chemotherapeutic agents could stimulate the inflammatory response. Surprisingly, this mechanism involves ROS activation of transcription factors linked to inflammatory processes in the cochlea. These studies have led to the use of anti-inflammatory agents for the treatment of hearing loss. Preliminary studies targeting inflammatory cytokines appear especially promising in preclinical studies. A primary goal of this project is to describe our current understanding of the oxidant hypothesis of noise and drug-induced hearing loss and show how this relates to cochlear inflammation. Several different aspects of the cochlear inflammatory process will be discussed in detail, ranging from the sources of inflammatory cells, chemokines, inflammatory cytokines, and cochlea resident immune cells. Molecular pathways leading to activation of the local inflammatory process will be highlighted and treatment options will be discussed. The relevance of certain clinically used anti-inflammatory interventions, such as trans-typmanic steroids will also be discussed. Furthermore, we will examine recent patents focusing on the use of anti-inflammatory agents for the treatment of drug and noise-induced hearing loss.

The auditory system is a complex neural system composed of many types of neurons connected into networks. One feature that sets the auditory system apart from other sensory systems, such as somatosensory or visual systems, is the many stages of neural processing that occur between the ear in the periphery and the cerebral cortex. Each stage is composed of specialized types of neurons connected in specific microcircuits that perform computations on the information about sound. To understand this processing, all the tools of neuroscience must be employed. The proposed text integrates cell biology, synaptic physiology, and electrophysiology to fully develop the topic, presenting an overview of the functional anatomy of the central auditory system. It is organized based on the neuronal connectivity of the central auditory system, which emphasizes the neurons, their synaptic organization, and their formation of functional pathways and microcircuits. The goal of the book is to stimulate research into the cell biology of the central auditory system and the characteristics of the specific neurons and connections that are necessary for normal hearing. Future research on the development of the central auditory including that employing stem cells will require such information in order to engineer appropriate therapeutic approaches.

Research in Communication Sciences and Disorders: Methods for Systematic Inquiry, Fourth Edition is a comprehensive yet comprehendible text meant for instructors and students of research methods in the field of communication sciences and disorders. This forward-thinking book reflects the movement toward evidence-based practice in speech-language pathology and audiology. The authors ensure that the concepts associated with evidence-based practice are integrated throughout the chapters. Rather than treating empirical research and searching for clinical evidence as separate topics, this text presents both as different applications of a process of scientific inquiry. The order of the chapters reflects the steps a researcher or clinician might complete when conducting an investigation. Also included are features that help students be more active in learning the material. Each chapter has a set of review questions or case scenarios that can be used as homework, as probe questions in class, or as a basis for group activities. In addition, the authors provide lists of supplemental readings from the research literature in the field. As with the previous edition, the fourth edition benefits instructors and students alike with access to a PluralPlus companion website. The website provides convenient lecture slides for each chapter and answers to review questions for instructors. For students, the website lists the key words for each chapter, provides links to supplemental websites and documents, and displays interactive versions of many of the figures within the text. New to the Fourth Edition New author: Jaimie L. Gilbert, PhD for an enhanced audiology perspective New chapter: Writing a Literature Review Reorganized for better flow of information. Various new and updated references to reflect the current state of research Additional illustrations and tables Expanded material on critical appraisal

This textbook is a product of William Bennett's work in developing and teaching a course on the physics of music at Yale University to a diverse audience of musicians and science students in the same class. The book is a culmination of over a decade of teaching the course and weaves together historical descriptions of the physical phenomena with the author's clear interpretations of the most important aspects of the science of music and musical instruments. Many of the historical examples are not found in any other textbook available on the market. As the co-inventor of the Helium-Neon laser, Prof. Bennett's knowledge of physics was world-class. As a professor at one of the most prestigious liberal-arts universities in the world, his appreciation for culture and humanities shines through. The book covers the basics of oscillations, waves and the analysis techniques necessary for understanding how musical instruments work. All types of stringed instruments, pipe organs, and the human voice are covered in this volume. A second volume covers the remaining families of musical instruments as well as selected other topics. Readers without a background in acoustics will enjoy learning the physics of the Science of Musical Sound from a preeminent scientist of the 20th century. Those well versed in acoustics will discover wonderful illustrations and photographs depicting familiar concepts in new and enlightening ways.

By far, the most widely used subjects in psychological and biological research today are rodents. Although rats and mice comprise the largest group of animals used in research, there are over 2,000 species and 27 families of rodents, living all over the world (except Antarctica) and thriving in many different habitat types. The vast environmental diversity that rodents face has led to numerous adaptations for communication, including vocalizing and hearing in both the sonic and ultrasonic ranges, effectively communicating in the open air and underground, and using vocalizations for coordinating sexual behavior, for mother-pup interactions, and for signaling an alarming situation to the group. Some rodent species have even developed foot drumming behaviors for communication. Comparative studies from around the globe, using both field and laboratory methodologies, reveal the vast differences in acoustic communication behavior across many rodent species. Some rodents are amenable to training and have been domesticated and bred purely for research purposes. Since the early 1900s, rats and mice have been indispensable to research programs around the world. Thus, much of what we know about hearing and vocalizations in rodents come from these two species tested in the laboratory. The sequencing of the mouse genome in 2002, followed by the rat genome in 2004, only increased the utility of these animals as research subjects since genetically engineered strains mimicking human diseases and disorders could be developed more easily. In the laboratory, rats and mice are used as models for human communication and hearing disorders and are involved in studies on hearing loss and prevention, hormones, and auditory plasticity, to name a few. We know that certain strains of mice retain hearing better than others throughout their lifespan, and about the genes involved in those differences. We know about the effects of noise, hormones, sex, aging, and circadian rhythms on hearing in mice and other rodents. We also know about normal hearing in many families of rodents, including the perception of simple and complex stimuli and the anatomy and physiology of hearing and sound localization. The importance of acoustic communication to these animals, as well as the significance of these mammals to biomedical research, are summarized in the chapters.

The evolution of vertebrate hearing is of considerable interest in the hearing community. However, there has never been a volume that has focused on the paleontological evidence for the evolution of hearing and the ear, especially from the perspective of some of the leading paleontologists and evolutionary biologists in the world. Thus, this volume is totally unique, and takes a perspective that has never been taken before. It brings to the fore some of the most recent discoveries among fossil taxa, which have demonstrated the sort of detailed information that can be derived from the fossil record, illuminating the evolutionary pathways this sensory system has taken and the diversity it had achieved.

The Auditory System at the Cocktail Party is a rather whimsical title that points to the very serious challenge faced by listeners in most everyday environments: how to hear out sounds of interest amid a cacophony of competing sounds. The volume presents the mechanisms for bottom-up object formation and top-down object selection that the auditory system employs to meet that challenge.

Each volume is independent and authoritative; taken as a set, this series is the definitive resource in the field.

This volume will serve as the first Handbook of its kind in the area of hearing aid research, often the least-defined, least-understood, part of the multi-disciplinary research process. Most scientific training is very advanced within the particular disciplines but provides little opportunity for systematic introduction to the issues and obstacles that prevent effective hearing-aid related research. This area has emerged as one of critical importance, as signified by a single specialized meeting (the International Hearing Aid Conference, IHCON) that brings together specialists from the disparate disciplines involved, including both university and industry researchers. Identification of the key steps that enable high-impact basic science to ultimately result in significant clinical advances that improve patient outcome is critical. This volume will provide an overview of current key issues in hearing aid research from the perspective of many different disciplines, not only from the perspective of the key funding agencies, but also from the scientists and clinicians who are currently involved in hearing aid research. It will offer insight into the experience, current technology and future technology that can help improve hearing aids, as scientists and clinicians typically have little or no formal training over the whole range of the individual disciplines that are relevant. The selection and coverage of topics insures that it will have lasting impact, well beyond immediate, short-term, or parochial concerns.

This volume presents a set of essays that discuss the development and plasticity of the vertebrate auditory system. The topic is one that has been considered before in the Springer Handbook of Auditory Research (volume 9 in 1998, and volume 23 in 2004) but the field has grown substantially and it is appropriate to bring previous material up to date to reflect the wealth of new data and to raise some entirely new topics. At the same time, this volume is also unique in that it is the outgrowth of a symposium honoring two-time SHAR co-editor Professor Edwin W Rubel on his retirement. The focus of this volume, though, is an integrated set of papers that reflect the immense contributions that Dr. Rubel has made to the field over his career. Thus, the volume concurrently presents a topic that is timely for SHAR, but which also honors the pioneer in the field. Each chapter explores development with consideration of plasticity and how it becomes limited over time. The editors have selected authors with professional, and often personal, connections to Dr. Rubel, though all are, in their own rights, outstanding scholars and leaders in their fields. The specific audience will be graduate students, postdoctoral fellows, and established psychologists and neuroscientists who are interested in auditory function, development, and plasticity. This volume will also be of interest to hearing scientists and to the broad neuroscience community because many of the ideas and principles associate with the auditory system are applicable to most sensory systems. The volume is organized to appeal to psychophysicists, neurophysiologists, anatomists, and systems neuroscientists who attend meetings such as those held by the Association for Research in Otolaryngology, the Acoustical Society of America, and the Society for Neuroscience.

Insect Hearing provides a broadly based view of the functions, mechanisms, and evolution of hearing in insects. With a single exception, the chapters focus on problems of hearing and their solutions, rather than being focused on particular taxa. The exception, hearing in Drosophila, is justified because, due to its ever growing toolbox of genetic and optical techniques, Drosophila is rapidly becoming one of the most important model systems in neurobiology, including the neurobiology of hearing. Auditory systems, whether insectan or vertebrate, must perform a number of basic tasks: capturing mechanical stimuli and transducing these into neural activity, representing the timing and frequency of sound signals, distinguishing between behaviorally relevant signals and other sounds and localizing sound sources. Studying how these are accomplished in insects offers a valuable comparative view that helps to reveal general principles of auditory function.

Translational Research is the interface between basic science and human clinical application, including the entire process from animal studies to human clinical trials (phases I, II, and III). Translational Research moves promising basic science results from the laboratory to bedside application. Yet, this transition is often the least-defined, least-understood part of the research process. Most scientific training programs provide little or no systematic introduction to the issues, challenges, and obstacles that prevent effective research translation, even though these are the key steps that enable high-impact basic science to ultimately result in significant clinical advances that improve patient outcome. This volume will provide an overview of key issues in translation of research from "bedside to bench to bedside", not only from the perspective of the key funding agencies, but also from the scientists and clinicians who are currently involved in the translational research process. It will attempt to offer insight into real-world experience with intellectual property and technology transfer activities that can help move auditory technologies ahead, as scientists and clinicians typically have little or no formal training in these areas. Translational Research in Audiology and the Hearing Sciences will be aimed at graduate students and postdoctoral investigators, as well as professionals and academics. It is intended to function as a high-profile and up-to-date reference work on Translational Research in the auditory sciences, emphasizing research programs in the traditional areas including drugs and devices, as well as less traditional, still emerging, areas such as sensorineural hearing loss, auditory processing disorder, cochlear implants and hearing aids, and tinnitus therapies.

The International Symposium on Hearing is a prestigious, triennial gathering where world-class scientists present and discuss the most recent advances in the field of human and animal hearing research. The 2015 edition will particularly focus on integrative approaches linking physiological, psychophysical and cognitive aspects of normal and impaired hearing. Like previous editions, the proceedings will contain about 50 chapters ranging from basic to applied research, and of interest to neuroscientists, psychologists, audiologists, engineers, otolaryngologists, and artificial intelligence researchers.

Although the fundamental principles of vocal production are well-understood, and are being increasingly applied by specialists to specific animal taxa, they stem originally from engineering research on the human voice. These origins create a double barrier to entry for biologists interested in understanding acoustic communication in their study species. The proposed volume aims to fill this gap, providing easy-to-understand overviews of the various relevant theories and techniques, and showing how these principles can be implemented in the study of all main vertebrate groups. The volume will have eleven chapters assembled from the world's leading researchers, at a level intelligible to a wide audience of biologists with no background in engineering or human voice science. Some will cover sound production in a particular vertebrate group; others will address a particular issue, such as vocal learning, across vertebrate taxa. The book will highlight what is known and how to implement useful techniques and methodologies, but will also summarize current gaps in the knowledge. It will serve both as a tutorial introduction for newcomers and a springboard for further research for all scientists interested in understanding animal acoustic signals.

This book represents the first interdisciplinary text on the emerging field of rehabilitative surgery, in which state of the art procedures from multiple surgical specialties are combined. It proposes a completely new framework for understanding, coordinating, and providing treatment for paralyzed or severely neurologically impaired patients and explains the potentially critical impact of surgery in creating a new baseline of functional status, thereby improving the patient's daily life. Every major aspect of reconstructive surgical treatment is considered, including anesthesia, orthopedic surgery, plastic surgery, neurosurgery, general surgery, vascular surgery, and otolaryngology. The most up-to-date and evidence-based surgeries are clearly described and evaluated, with coverage of treatment of pressure sores, placement of feeding tubes, and upper extremity interventions to improve function and hygiene. Cutting-edge protocols are presented for the surgical treatment of severe nerve injuries, spinal cord injuries, and stroke or cerebrovascular accidents, and a first description and evaluation of phrenic nerve repair to assist weaning of paralyzed patients from ventilators is provided. Both surgical and nonsurgical readers will find this book to be an ideal guide and reference.
