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.

The U.S. Census Bureau has reported that 56.7 million Americans had some type of disability in 2010, which represents 18.7 percent of the civilian noninstitutionalized population included in the 2010 Survey of Income and Program Participation. The U.S. Social Security Administration (SSA) provides disability benefits through the Social Security Disability Insurance (SSDI) program and the Supplemental Security Income (SSI) program. As of December 2015, approximately 11 million individuals were SSDI beneficiaries, and about 8 million were SSI beneficiaries. SSA currently considers assistive devices in the nonmedical and medical areas of its program guidelines. During determinations of substantial gainful activity and income eligibility for SSI benefits, the reasonable cost of items, devices, or services applicants need to enable them to work with their impairment is subtracted from eligible earnings, even if those items or services are used for activities of daily living in addition to work. In addition, SSA considers assistive devices in its medical disability determination process and assessment of work capacity. The Promise of Assistive Technology to Enhance Activity and Work Participation provides an analysis of selected assistive products and technologies, including wheeled and seated mobility devices, upper-extremity prostheses, and products and technologies selected by the committee that pertain to hearing and to communication and speech in adults.

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 study compared perceptual differences between premium and mid-level hearing aids from a major manufacturer in normal hearing listeners. Limited literature currently exists comparing perceptual differences between premium and mid-level digital hearing aids. This information is highly important in decision-making for clinicians and patients alike. Barry et al. (2018) evaluated four major hearing aid models' noise reduction properties and determined that one manufacturer's premium and mid-level devices demonstrated significant differences in noise reduction gain in frequencies associated with human speech. We programmed this device for a mild sloping to moderately-severe SNHL using the manufacturer's proprietary fitting formula and noise reduction at its maximum setting. The hearing aid was mounted on KEMAR and ten Hearing in Noise Test (HINT) sentences were recorded with each device (premium and mid-level) at two different signal to noise ratios (SNR): 0 dB SNR and +5 dB SNR. Normal hearing listeners (n = 19) were blindly presented with the pair of stimuli at each signal to noise ratio condition with a three-alternative forced choice paradigm, whereby they indicate which presentation they preferred, or if there was no perceptual differences between the recordings. The preferences were made by each subject on the basis of three different criteria: noisiness, speech intelligibility, and overall quality. The findings of this study are consistent with previous research and suggest that there is no subjective difference between premium and mid-level hearing aids on measures of noisiness, speech intelligibility, and overall sound quality. Overall, data suggested that participants did not perceive a statistically significant difference between technology levels for either the 0 dB SNR condition or the +5 dB SNR condition. This suggests that in both very noisy and less noisy environments, normal-hearing listeners do not perceive any advantage when listening with premium technology. Future research should examine premium and mid-level technology with objective outcome measures and utilize subjects with hearing loss. It may be useful to examine differences between the devices on measures of listening effort as well.

This book discusses the history of hearing aids, their design, currently available advances from the perspective of an otolaryngologist. This book has been designed to fill the knowledge gap that exists amongst otolaryngologists on this topic. Being surgeons otolaryngologists pay very little attention to this topic. Current advances in the field of electronics have not only improved the quality of hearing aids but also made them very small. Miniaturization in electronics has played a vital role in shrinking the size of these hearing aids. With the advancements that are taking place in battery technology the future hearing aids will not only remain small but also would be more powerful.
