Available in PDF, EPUB and Kindle. Book excerpt: Transient-Evoked Otoacoustic Emissions (TEOAE) are nonstationary acoustic signals coming from the inner ear after acoustic stimulation by clicks and they are applied as tools in newborn hearing screening programs to allow the early identification of hearing loss and the consequent diagnosis and intervention. In any screening program, the duration of each test is a crucial parameter. For TEOAE, it is strongly influenced by the acquisition procedure, typically based on classical synchronous averaging technique over 260 sweeps, with an average acquisition time of about 2-3 minutes. This paper present an application of Principal Component Analysis (PCA) to rapidly-acquired TEOAE (averaged over only 10, 60 or 100 sweeps) for the detection of this type of cochlear response. The PAC approach is shown to be able to enhance the signal-to-noise ratio (SNR) and, in turn, to allow a correct detection of the responses. Results of the application of this approach in comparison with responses recorded, from the same wars, with classical technique will be shown. The reduction of the acquisition time to about one fourth with respect to its typical value and with approximately the same final signal-to-noise ratio will be discussed.

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 Biophysics of the Cochlea written by Ernst Dalhoff and published by World Scientific. This book was released on 2003 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of an international hearing-research conference held in Germany 2002. The conference brought together experts in genetics, molecular and cellular biology, physiology, engineering, physics, mathematics, audiology and medicine to synthesize and extend our understanding of how the cochlea works. Topics are discussed experimentally and theoretically at the molecular, cellular and whole-organ levels. Some of the topics are: mechanosensitivity of motor proteins; mechanochemical transduction by motor proteins; mechanoelectrical transduction in the stereocilia of hair cells; electromechanical transduction in the stereocilia, soma and synapses of hair cells; multidimensional vibration of the organ of Corti; and otoacoustic emissions. This book will be invaluable to researchers and students in auditory science.

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.

Download or read book Cochlear Mechanics written by Frank Böhnke and published by S. Karger AG (Switzerland). This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This special issue collects our current knowledge of the mechanical processing of acoustic signals by the cochlea and its containing structures. Many workers in diverse disciplines in otology use the facts from cochlear mechanics for the interpretation of their results. Presented here for the first time is the development of a three-dimensional mechanical model of the curved cochlea including fluid-structure couplings. An important approach for future cochlear modeling is shown by the provision of geometrical data for the input of three-dimensional finite element models by microtomographic imaging. A remarkable article tries to demonstrate a connection between outer hair cell mechanics and the complex phenomenon of tinnitus and will be of special interest for stress engineers. Owing to its strong interdisciplinarity, this issue is not only intended for biophysicists, ENT clinicians and audiologists but also for radiologists, biomechanical engineers and computer engineers.
