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.

Book excerpt: Many U. S. Air Force Flight Surgeons, medical officers, and others concerned with the conduct of hearing conservation programs have expressed the need for a set of guidelines to be used in the interpretation of audiometric data. Although the air conduction audiogram does not provide sufficient information to allow a definitive diagnosis to be made, it usually gives an indication as to whether a hearing loss is conductive or sensorineural in origin. In addition, determination may be made from the audiogram as to what further testing should be carried out and what action may be necessary to prevent further hearing loss. A method for interpretation of audiometric data is presented. An explanation of the various audiometric contours is given, followed by a step-by-step procedure for analyzing the pure-tone audiogram. In addition, recommendations are made concerning the handling of patients whose audiograms are not within normal limits. Utilization of these procedures within a compreshensive program of hearing testing, noise control, and education is recommended wherever personnel work in hazardous noise. They should also be helpful in dealing with other types of hearing losses. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2018-04-03 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bone conduction is usually understood as the hearing sensation based on the vibrations of the skull bone and surrounding tissues. The fact that vibration of the skull bones can result in a sound percept has been known for a long time. However, it is difficult to give a general definition of BC sound. Normally, BC sound is described as the sound energy transmitted through the body (comprising the solid and fluid parts) then the outer, middle and inner ear are involved and finally produce a perception of sound. Even if BC sound perception has been studied for more than a century, the whole pattern of BC sound transmission is still not complete. There are limitations for experimental investigation of BC sound, such as the complexity of experimental manipulations and individual differences between subjects resulting in difficult to interpret outcomes. One way to overcome some of those issues is the use of a simulation model for BC sound. However, until now, the published models are unable to provide a holistic response of BC sound in the human. Therefore, the primary aim of this thesis is to develop a finite element model that could simulate BC sound transmission in the human. Based on cryosectional images of a female, the LiUHead was developed as a FE model of the human head with the structure and material properties of real human. Most the structures and tissues which could contribute to the BC transmission were included in the LiUHead. The simulation results of the LiUHead agreed with experimental data obtained in both cadaver heads and live humans. After the development and validation of the LiUHead, the model was used to investigate BC sound. Since BC sound is transmitted in and between the tissues, the power transmission of BC sound was investigated in the LiUHead in the frequency domain. When the stimulation was applied on the surface of the skull at the mastoid position, the results of the simulations show that, as the name suggest, the skull bone dominants the BC sound transmission. The soft tissues and cartilages are as the second most important media of the BC sound while the skull interior is the least important for the BC transmission. Moreover, according to the power flux in the skull, the BC vibrations are mainly concentrated at the skull base. Other important transmission pathways are located at the occipital bone at the posterior side of the head, but the power transmitted over the face, forehead and vertex is minor. There is power interaction between the skull bone and skull interior near the stimulation position but the transmission of sound power through the brain seem to be minimal. Since the power or energy is difficult to measure in an experimental setting, this investigation gave unique knowledge about BC sound transmission in the head and the interaction between the tissues. As a common application for BC sound, bone-conduction devices are used to stimulate the hearing and is a method for hearing loss rehabilitation. Nowadays many different kinds of BCDs are available. However, most studies failed to compare the different types of BCDs in the same conditions as well as between several BCDs as it is not possible to compare several BCDs within the same subject due to the implantation required for several BCDs. The model gives a unique opportunity to evaluate various BCDs in the same head. Eight different BCDs, including four kinds of skin-drive BCDs, three kinds of direct-drive BCDs, and one in-the-mouth device, were applied to the LiUHead and the simulation results were evaluated. The results proved that the direct-drive BCDs and the in-the-mouth device gave similar vibration responses at the cochlea. At low frequencies, the skin-drive BCDs had similar or even better cochlear responses than the direct-drive BCDs. However, the direct-drive BCDs gave stable responses at mid-frequencies and gave higher responses than the skin-drive BCDs at high frequencies. These results are beneficial evaluating and for designing and improving current BCDs. The ultimate goal of this thesis is to provide a computational model for BC sound that can be used for evaluation of BC sound transmission. This was accomplished by the LiUHead that gave results comparable to experimental data and enabled investigations that cannot easily be conducted in experiments.

Available in PDF, EPUB and Kindle. Book excerpt: The middle ear plays a vital role in the sense and sensitivity of hearing. Of the various characteristics that distinguish mammals from other vertebrates, several pertain specifically to the middle-ear system, such as the presence of three middle-ear bones and the four-layer composite structure of the tympanic membrane. The Middle Ear attempts to elucidate the role this system plays in sound transmission, as viewed from both scientific and clinical perspectives.
Download or read book Hearing Its Function and Dysfunction written by E.D. Schubert and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is one in a series of monographs being issued under the general title of "Disorders of Human Communication". Each monograph deals in detail with a particular aspect of vocal communication and its disorders, and is written by internationally distinguished experts. Therefore, the series will provide an authoritative source of up-to-date scientific and clinical informa tion relating to the whole field of normal and abnormal speech communication, and as such will succeed the earlier monumental work "Handbuch der Stimm und Sprachheilkunde" by R. Luchsinger and G. E. Arnold (last issued in 1970). This series will prove invaluable for clinicians, teachers and research workers in phoniatrics and logopaedics, phonetics and linguistics, speech pathology, otolaryngology, neurology and neurosurgery, psychology and psychiatry, paediatrics and audiology. Several of the monographs will also be useful to voice and singing teachers, and to their pupils. G. E. Arnold, Jackson, Miss. August 1980 F. Wincke1, Berlin B. D. Wyke, London Preface Despite years of interest and research in the hearing process, much of the exact detail of auditory processing remains in the realm of conjecture. We do have some rudimentary understanding of the way the system records changes in frequency and intensity and of the relations between the ear's spectrum analysis and our identification of sound quality. Some of these operations we can duplicate with auditory models of our own, or with laboratory analyzers that can serve as auditory analogs.
