Book Description
Auditory Sound Transmission provides an integrated, state-of-the-art description and quantitative analysis of sound transmission from the outer ear to the sensory cells in the cochlea of the inner ear. It describes in detail the structures and mechanisms involved and gives their input and transmission characteristics. It shows how sound transmission in one part of the ear depends on the input characteristics of the next part and how sound is analyzed in the inner ear before it reaches the nervous system. The book is divided into seven chapters. The first gives the general overview of the path of sound in the ear. The second concerns the acoustics of the outer ear which is important not only for sound transmission in the ear but also for the design and calibration of earphones, as well as for clinical and research measurements of sound pressure in the ear canal. The third chapter analyzes the middle ear function which is crucial for adapting the conditions of sound propagation in the air to those in the inner ear fluids. The middle ear is prone to various malfunctions, and it is shown how they change the acoustic conditions measured in the ear canal and can be diagnosed on this basis. The next three chapters are dedicated to the most intricate mechanical part of the auditory system, the cochlea. Because of its complexity, its function is explained in three steps: first, with the help of simplifications produced by death; second, on the basis of the measured characteristics of the live organ; third, with the help of quantitative analysis. The last chapter describes cochlear mechanisms underlying pitch and loudness perception.

Book Description
Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.

Book Description
The Auditory System and Human Sound-Localization Behavior provides a comprehensive account of the full action-perception cycle underlying spatial hearing. It highlights the interesting properties of the auditory system, such as its organization in azimuth and elevation coordinates. Readers will appreciate that sound localization is inherently a neuro-computational process (it needs to process on implicit and independent acoustic cues). The localization problem of which sound location gave rise to a particular sensory acoustic input cannot be uniquely solved, and therefore requires some clever strategies to cope with everyday situations. The reader is guided through the full interdisciplinary repertoire of the natural sciences: not only neurobiology, but also physics and mathematics, and current theories on sensorimotor integration (e.g. Bayesian approaches to deal with uncertain information) and neural encoding. Quantitative, model-driven approaches to the full action-perception cycle of sound-localization behavior and eye-head gaze control Comprehensive introduction to acoustics, systems analysis, computational models, and neurophysiology of the auditory system Full account of gaze-control paradigms that probe the acoustic action-perception cycle, including multisensory integration, auditory plasticity, and hearing impaired

Book Description
Sound Propagation Sound propagates through air as a longitudinal wave. The speed of sound is determined by the properties of the air, and not by the frequency or amplitude of the sound. Sound waves, as well as most other types of waves, can be described in terms of the following basic wave phenomena.

Book Description
Acoustic Communication in Birds, Volume 1: Production, Perception, and Design Features of Sounds presents the scientific study of bird vocalizations. This book discusses the relations between the physical structure of bird vocalization and their quality as perceived by the recipient. Organized into nine chapters, this volume begins with an overview of the first sound recording of bird sound. This text then outlines some of the complex processes and events between sound production and behavior response to sound. Other chapters consider the study of neural control of vocalizations in birds. This book discusses as well the acoustic information transmitted through the wide range of habitats plays a crucial role in different avian behaviors, including individual and species recognition, territorial defense, mate selection, and song learning. The final chapter deals with a more detailed functional interpretation of a particular sound. This book is a valuable resource for ornithologists, ethologists, and research workers.

Book Description
This book examines the human factors issues associated with the development, testing, and implementation of helmet-mounted display technology in the 21st Century Land Warrior System. Because the framework of analysis is soldier performance with the system in the full range of environments and missions, the book discusses both the military context and the characteristics of the infantry soldiers who will use the system. The major issues covered include the positive and negative effects of such a display on the local and global situation awareness of the individual soldier, an analysis of the visual and psychomotor factors associated with each design feature, design considerations for auditory displays, and physical sources of stress and the implications of the display for affecting the soldier's workload. The book proposes an innovative approach to research and testing based on a three-stage strategy that begins in the laboratory, moves to controlled field studies, and culminates in operational testing.

Book Description
Three decades after the introduction of the first bone-anchored hearing aids, the available systems have improved significantly and the field is expanding faster than ever. New technologies such as digital signal processing have opened new avenues unique to bone conduction hearing aids. Better insights into the physiology of bone-conducted hearing have not only changed the field but also provided ideas for new areas of application.In this volume of Advances in Oto-Rhino-Laryngology, renowned researchers and experienced clinicians from all over the world present the latest findings and practices. Reviews on the theoretical background of bone conduction hearing, presentation of currently available hearing aid systems, chapters on monaural and binaural hearing with implantable bone conduction hearing aids, a comparison with conventional hearing aids and a glimpse into the future of implantable bone conduction hearing aids render this volume an invaluable reference book to ENT surgeons, audiologists, hearing aid acousticians and researchers alike.
