Available in PDF, EPUB and Kindle. Book excerpt: AbstractConductive hearing loss results when the neural integrity of the auditory system is healthy, but sound is prevented from reaching the cochlea in its entirety. Unilateral Congenital Aural Atresia (UCAA) is a birth defect in which there is no external ear canal, resulting in the reduction of sound able to reach the middle ear. Two primary options for correcting this conductive hearing loss are canalplasty or a bone anchored hearing device (BAHD). We want to compare the benefit level from these options, specifically in two conditions: sound localization and the ability to detect speech from one ear while there is competing background noise presented to the other ear. While canalplasty has been well studied, there is little research available on whether a unilateral bone conduction implant will provide any benefit in these binaural tasks. The purpose of this study is to determine the effect BAHD use has on localization and speech in noise understanding, so that audiologists and ENTs can advise patients of their treatment options. A stereo computer and semi-circular speaker setup was used to determine sound-localization accuracy of the participants by having them select which speaker they thought the signal noise was being presented from. Performance was quantified through percent correct and root mean squared of error in degrees azimuth. Speech in noise understanding was assessed through four different test conditions in which the participant chose the color and number spoken by a randomized recording, while competing noise played from the opposite hemifield. Data were analyzed in terms of signal-to-noise ratio. Two separate studies were designed for this dissertation. In the single-subject design, one participant had asymmetrical conductive hearing loss and took both tests twice a day, alternating BAHD use daily, for a total of six days. In the multi-subject design, six patients with UCAA each took both tests while unaided, and then again with their BAHD activated. Results showed that while BAHD use does not produce significant benefits in localization or speech in noise comprehension for all users, the unaided thresholds for asymmetry of hearing and air-bone gaps (ABGs) are predictive of whether an individual will benefit from implantation or not in these tasks. More specifically, if pre-implantation thresholds are poor (~>44dB), then activation of the BAHD improves these two aspects of binaural processing; conversely, with relatively minor asymmetry BAHD activation makes binaural processing worse.

Download or read book Hearing Loss written by National Research Council and published by National Academies Press. This book was released on 2004-12-17 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Hearing Health Care for Adults written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. 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.

This book was released on 2017-09-01 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The Institute of Medicine carried out a study mandated by Congress and sponsored by the Department of Veterans Affairs to provide an assessment of several issues related to noise-induced hearing loss and tinnitus associated with service in the Armed Forces since World War II. The resulting book, Noise and Military Service: Implications for Hearing Loss and Tinnitus, presents findings on the presence of hazardous noise in military settings, levels of noise exposure necessary to cause hearing loss or tinnitus, risk factors for noise-induced hearing loss and tinnitus, the timing of the effects of noise exposure on hearing, and the adequacy of military hearing conservation programs and audiometric testing. The book stresses the importance of conducting hearing tests (audiograms) at the beginning and end of military service for all military personnel and recommends several steps aimed at improving the military services' prevention of and surveillance for hearing loss and tinnitus. The book also identifies research needs, emphasizing topics specifically related to military service.
Download or read book Captioning and Subtitling for d Deaf and Hard of Hearing Audiences written by Soledad Zárate and published by UCL Press. This book was released on 2021-01-14 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Captioning and Subtitling for d/Deaf and Hard of Hearing Audiences is a comprehensive guide to the theory and practice of captioning and subtitling, a discipline that has evolved quickly in recent years. This guide is of a practical nature and contains examples and exercises at the end of each chapter. Some of the tasks stimulate reflection on the practice and reception, while others focus on particular captioning and SDH areas, such as paralinguistic features, music and sound effects. The requirements of d/Deaf and hard of hearing audiences are analysed in detail and are accompanied by linguistic and technical considerations. These considerations, though shared with generic subtitling parameters, are discussed specifically with d/Deaf and hard of hearing audiences in mind. The reader will become familiar with the characteristics of d/Deaf and hard of hearing audiences, and the diversity – including cultural and linguistic differences – within this group of people. Based on first-hand experience in the field, the book also provides a step-by-step guide to making live performances accessible to d/Deaf and hard of hearing audiences. As well as exploring all linguistic and technical matters related to the creation of captions, aspects related to the overall set up of the captioned performance are discussed. The guide will be valuable reading to students of audiovisual translation at undergraduate and postgraduate level, to professional subtitlers and captioners, and to any organisation or venue that engages with d/Deaf and hard of hearing people.
