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
Notes that in the decade since the first edition, speech audiometry has been almost entirely replaced by electrophysiological tests in many countries for advanced diagnosis, but that many countries do not have such sophisticated equipment or training, and that audiology is still used for rehabilitation. Explains such aspects as the basic properties of speech, speech tests in quiet and noise as a measure of auditory processing, equipment and its calibration, speech tests of hearing for children, and experiences in a number of countries and institutions.

Book Description
In communication acoustics, the communication channel consists of a sound source, a channel (acoustic and/or electric) and finally the receiver: the human auditory system, a complex and intricate system that shapes the way sound is heard. Thus, when developing techniques in communication acoustics, such as in speech, audio and aided hearing, it is important to understand the time–frequency–space resolution of hearing. This book facilitates the reader’s understanding and development of speech and audio techniques based on our knowledge of the auditory perceptual mechanisms by introducing the physical, signal-processing and psychophysical background to communication acoustics. It then provides a detailed explanation of sound technologies where a human listener is involved, including audio and speech techniques, sound quality measurement, hearing aids and audiology. Key features: Explains perceptually-based audio: the authors take a detailed but accessible engineering perspective on sound and hearing with a focus on the human place in the audio communications signal chain, from psychoacoustics and audiology to optimizing digital signal processing for human listening. Presents a wide overview of speech, from the human production of speech sounds and basics of phonetics to major speech technologies, recognition and synthesis of speech and methods for speech quality evaluation. Includes MATLAB examples that serve as an excellent basis for the reader’s own investigations into communication acoustics interaction schemes which intuitively combine touch, vision and voice for lifelike interactions.

Book Description
Otolaryngology Head and Neck Surgery is the medical and surgical specialty addressing disorders of the head and neck in both adult and pediatric populations. The goal of the encyclopedia is to serve as a single and comprehensive source of all the information that is essential for students and practitioners of the specialty. The vast amount of information included in the encyclopedia is divided into 5 volumes in line with the subspecialties of general otolaryngology, head and neck surgery, pediatric otolaryngology, otology–neurotology, and facial plastics. All volume editors are internationally recognized otolaryngologists with experience in publishing. Each section editor recruited experienced authors from all over the world to contribute on structured topics, and all entries are supported by published references. Thus, all information included in the encyclopedia is from credible sources and has been carefully screened for accuracy. The strength of the encyclopedia is its online availability and quick search features, which allow rapid retrieval of definitions and more in-depth information. Key words are hyperlinked to provide a gateway to numerous referenced manuscripts, journals, and books.

Book Description
Hearing Impairment - An Invisible Disability is the first work of its kind to comprehensively cover all aspects of hearing impairment. It covers the following categories through more than 100 contributions from all over the world to constitute an encyclopedia of hearing impairment: - Hearing Basics: What does hearing impairment mean? Its causes and effects are explained through many real-world examples. - Children: Childhood is a time when hearing impairment often begins, so proper treatment at an early stage can help alleviate difficulties and allow for as normal a life as possible. Many case studies from both the developed and developing parts of the world, including Indonesia and Latin America in the latter category, are provided to aid comprehension. - Hearing Aids: Through newly emerging technology and with the help of electronics companies, new and affordable hearing aids are being developed and marketed. The authors take a closer look at this burgeoning field. - Medical Aspects: Medical treatment of hearing impairment has recently shown remarkable change, manifested in improved techniques and applications all over the world. Although mainly of relevance to researchers and practicing physicians, the clear explanation of the medical and technical terminology is likely to be of interest to all concerned with the future of hearing impairment. - Social and International Help: With a wealth of assistance from individuals, NGOs, and international organizations specifically tailored to help the hearing impaired, those in need of guidance can gain confidence from the knowledge that substantial support is available to help them pursue a full and varied life.

Book Description
The acoustics of a space can have a real impact on the sounds you create and capture. Acoustics and Psychoacoustics, Fifth Edition provides supportive tools and exercises to help you understand how music sounds and behaves in different spaces, whether during a performance or a recording, when planning a control room or listening space, and how it is perceived by performers, listeners, and recording engineers. With their clear and simple style, Howard and Angus cover both theory and practice by addressing the science of sound engineering and music production, the acoustics of musical instruments, the ways in which we hear musical sounds, the underlying principles of sound processing, and the application of these concepts to music spaces to create professional sound. This new edition is fully revised to reflect new psychoacoustic information related to timbre and temporal perception, including an updated discussion of vocal fold vibration principles, samples of recent acoustic treatments, and a description of variable acoustics in spaces, as well as coverage of the environment’s effect on production listening, sonification, and other topics. Devoted to the teaching of musical understanding, an accompanying website (www.routledge.com/cw/howard) features various audio clips, tutorial sheets, questions and answers, and trainings that will take your perception of sound to the next level. This book will help you: Gain a basic grounding in acoustics and psychoacoustics with respect to music audio technology systems Incorporate knowledge of psychoacoustics in future music technology system designs as appropriate Understand how we hear pitch, loudness, and timbre Learn to influence the acoustics of an enclosed space through designed physical modifications
