Hearing Health Care for Adults by National Academies of Sciences, Engineering, and Medicine,Health and Medicine Division,Board on Health Sciences Policy,Committee on Accessible and Affordable Hearing Health Care for Adults Pdf

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.

Compression for Clinicians: a Compass for Hearing Aid Fittings, Third Edition by Theodore H. Venema Pdf

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.

Active Middle Ear Implants by Klaus Böheim Pdf

In recent years, methods for coupling active implants to the middle ear, round window or combinations of passive middle ear prostheses have progressed considerably. Patient selection criteria have expanded from purely sensorineural hearing losses to conductive and mixed hearing losses in difficult-to-treat ears. This book takes into consideration recently developed methods as well as devices in current use. It begins with a fascinating and authentic history of active middle ear implants, written by one of the main pioneers in the field. In the following chapters, leading scientists and clinicians discuss the relevant topics in otology and audiology. Treatments for sensorineural hearing loss, conductive and mixed hearing losses, and results on alternative coupling sites such as the stapes footplate and the oval window are also covered, as well as articles on candidacy and cost-effectiveness. This publication is a must for ENT professionals and surgeons seeking out the latest knowledge on current research and clinical applications of active middle ear implants for all types of hearing loss.
