This book was released on 2016-10-06 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: The loss of hearing - be it gradual or acute, mild or severe, present since birth or acquired in older age - can have significant effects on one's communication abilities, quality of life, social participation, and health. Despite this, many people with hearing loss do not seek or receive hearing health care. The reasons are numerous, complex, and often interconnected. For some, hearing health care is not affordable. For others, the appropriate services are difficult to access, or individuals do not know how or where to access them. Others may not want to deal with the stigma that they and society may associate with needing hearing health care and obtaining that care. Still others do not recognize they need hearing health care, as hearing loss is an invisible health condition that often worsens gradually over time. In the United States, an estimated 30 million individuals (12.7 percent of Americans ages 12 years or older) have hearing loss. Globally, hearing loss has been identified as the fifth leading cause of years lived with disability. Successful hearing health care enables individuals with hearing loss to have the freedom to communicate in their environments in ways that are culturally appropriate and that preserve their dignity and function. Hearing Health Care for Adults focuses on improving the accessibility and affordability of hearing health care for adults of all ages. This study examines the hearing health care system, with a focus on non-surgical technologies and services, and offers recommendations for improving access to, the affordability of, and the quality of hearing health care for adults of all ages.
Download or read book Binaural Interference a Guide for Audiologists written by James Jerger and published by Plural Publishing. This book was released on 2018-02-23 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Binaural interference occurs when the speech input to one ear interferes with the input to the other ear during binaural stimulation. The first published study on binaural interference twenty-five years ago demonstrated that some individuals, particularly older individuals, perform more poorly with two hearing aids than with one and/or more poorly with binaural than monaural stimulation on electrophysiologic as well as behavioral measures. Binaural interference is relevant to every audiologist because it impacts the successful use of binaural hearing aids and may explain communicative difficulty in noise or other challenging listening situations in persons with normal-hearing sensitivity as well as persons with hearing loss. This exciting new book written by two highly respected audiologists first traces the history of its study by researchers, then reviews the evidence, both direct and indirect, supporting its reality. This is followed by a discussion of the possible causes of the phenomenon and in-depth analysis of illustrative cases. The authors outline a systematic approach to the clinical detection, evaluation and amelioration of individuals who exhibit binaural interference. Suggestions are furnished on improved techniques for evaluation of the binaural advantage in general and on sensitized detection of the disorder in particular. The book ends with recommendations for future directions. Given the adverse impact of binaural interference on auditory function and its occurrence in a significant subset of the population with hearing loss, as well as in some individuals with normal-hearing sensitivity, research on binaural interference only recently has begun to flourish, and adaptation of audiologic clinical practice to identify, assess, and manage individuals with binaural interference has yet to become widespread. The authors intend for the book to provide impetus for pursuing further research and to encourage audiologists to explore the possibility of binaural interference when patient complaints suggest it and when performing audiologic evaluations. The book is intended for practicing clinical audiologists, audiology students, and hearing scientists.

Download or read book Compression for Clinicians written by Theodore H. Venema and published by Plural Publishing. This book was released on 2016-10-30 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compression for Clinicians: A Compass for Hearing Aid Fittings, Third Edition explains many developments that have taken place in the world of hearing aid compression, fitting methods, and real ear measurement. The text aims to make difficult concepts easier to understand and to explain in plain language many topics pertaining to compression. Directional microphones and digital features of noise reduction, feedback reduction, and expansion are also covered. The third edition recognizes two distinct clinical populations of sensorineural hearing loss: mild to moderate, on one hand, and more severe, on the other. These two clinical populations are well served by a corresponding pair of compression types: wide dynamic range compression and output limiting compression. Another double distinction held throughout the text is the two-part task for all hearing aids: providing gain and also increasing the signal-to-noise ratio. Gain is addressed by compression, while listening in noise is addressed by directional microphones and digital noise reduction. The Third Edition: Includes new chapters on common clinical encounters (Chapter 1), real ear measurement (Chapter 5), and adaptive dynamic range optimization (Chapter 10)Distinguishes between "sensory" and "neural" hearing loss and devotes a separate chapter to each of these types of sensorineural hearing lossContains updated coverage of digital hearing aids, directional microphones, and digital noise reductionRetains a strong focus on the historical development of compression from yesterday's analog hearing aids to digital hearing aids of today Compression for Clinicians is intended for those studying to become hearing health care professionals, including audiologists and hearing instrument practitioners. It is also intended for practicing clinicians who simply want to refresh their knowledge base concerning hearing loss and hearing aids. Clinically relevant and very thorough, it provides a compass in the world of compression hearing aids.

Download or read book Speech Mapping and Probe Microphone Measurements written by H. Gustav Mueller and published by Plural Publishing. This book was released on 2017-04-05 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written in an engaging, easy-to-read format by three of the industry's leading experts, Speech Mapping and Probe Microphone Measurements is an essential clinical companion for all practitioners fitting and dispensing hearing aids. The key to successful hearing aid fittings is the patient-specific programming of gain and output. As outlined in all Best Practices Guidelines, the cornerstone of this process is the real-ear verification. Although speech mapping and probe-microphone measures have been used clinically for decades, new techniques and procedures continue to emerge. This is the first handbook to be published in 25 years that is dedicated to this critical clinical measure. Starting with an emphasis on evidenced-based practice, and the need to develop a well-researched gold standard, Speech Mapping and Probe Microphone Measurements takes you through the process of conducting valid and reliable speech mapping testing. Following a review of the basics of signal types, presentation levels, and patient and probe positioning, the chapters flow to the patient-centered real-ear verification process. In addition to extensive step-by-step guidelines regarding the routine testing and adjustment of gain and output, protocols for the evaluation of special features and fittings also are outlined. As a bonus, the authors provide a review of how speech mapping findings can be used with other measures that are part of the overall hearing aid fitting protocol.
