Download Hearing Loss Book in PDF, ePub and Kindle
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 Auditory Evoked Potentials Book in PDF, ePub and Kindle
Written by experts with extensive clinical and scientific experience, this comprehensive textbook presents the state of the art in auditory evoked potentials. Opening chapters explain the nature of electrical fields that generate surface recorded potentials, summarize the imaging modalities that complement evoked potential studies, and review acoustics and instrumentation. Major sections examine the anatomy and physiology of the auditory periphery, brainstem, and cortex and the principles and clinical applications of auditory, myogenic, visual, somatosensory, and vestibular evoked potentials. Chapters present hands-on laboratory exercises and clinical case studies. A full-color insert includes 3D images from multi-channel evoked potentials and functional imaging.

Download Auditory Processing Of Temporal Fine Structure: Effects Of Age And Hearing Loss Book in PDF, ePub and Kindle
The book is concerned with changes in the perception of sound that are associated with hearing loss and aging. Hearing loss affects about 7% of the population in developed countries, and the proportion is increasing as the average age of the population increases. The audiogram is the most widely used diagnostic tool in audiology clinics around the world. The audiogram involves measuring the threshold for detecting sounds of different frequencies. Sometimes the audiogram is the only diagnostic tool that is used. However, hearing problems are not completely characterized by the audiogram. Two individuals with similar audiograms may show very different abilities in the detection and discrimination of sounds at above-threshold levels. Also, a person may have hearing difficulties despite having an audiogram that is within the range conventionally considered as ‘normal’. One factor that may influence the discrimination of sounds, especially the ability to understand speech in background sounds, is sensitivity to temporal fine structure (TFS).This monograph reviews the role played by TFS in masking, pitch perception, speech perception, and spatial hearing, and concludes that cues derived from TFS play an important role in all of these. Evidence is reviewed suggesting that cochlear hearing loss reduces the ability to use TFS cues. Also, the ability to use TFS declines with increasing age even when the audiogram remains normal. This provides a new dimension to the changes in hearing associated with aging, a topic that is currently of great interest in view of the increasing proportion of older people in the population.The study of the role of TFS in auditory processing has been a hot topic in recent years. While there have been many research papers on this topic in specialized journals, there has been no overall review that pulls together the different research findings and presents and interprets them within a coherent framework. This monograph fills this gap.

Download The Effect of Auditory Training on the Auditory Discrimination Ability of the Contralateral Ear Book in PDF, ePub and Kindle
The purpose of this study was to determine whether one ear of a profoundly deaf student could duplicate a response rate similar to the response rate achieved by the opposite ear on an auditory training program. The formal hypothesis of this study was: a student that reaches criterion level of acceptable performance in the right ear on one presentation of Auditory Training Program No. V will achieve the same criterion level of acceptable performance during the first presentation of the last twenty test slides of Auditory Training Program No. V to the left ear. In observation of clinical performance oft hearing impaired patients, it was reported that often the-discrimination score of one ear improves or remains the same after a hearing aid is fitted to that ear for a length of time. At the same time, the contralateral ear, i.e., the ear not fitted with a hearing aid, fails to maintain or improve its ability to respond to speech discrimination tests. Since a review of the literature failed to reveal any existing research explaining this observation, an investigation into this problem appeared warranted. Three subjects were selected for the purpose of this investigation, two males and one female. Each subject was a student in high school at the Oregon State School for the Deaf. Of the three subjects, two were juniors, and one was a senior. All three subjects possessed hearing levels below 110dB (ISO 1964 standards). To evaluate the hypothesis, each subject was first given a pretest trial to determine the discrimination ability of each ear when presented with Auditory Program No. V. Then the right ear of all three subjects was trained to a predetermined criterion level of acceptable performance. For each day that a treatment phase was presented to a subject, the remaining successive subject(s) was/were given the twenty test slide sequence of the auditory training program. A post-test of the left ear followed the training of the right ear, and this was compared to the pretest score achieved by the left ear at the beginning of the treatment period. To support the hypothesis of this study, the left ear would have to demonstrate a response rate comparable to the trained right ear on one presentation of the training program. Results of the study indicate that the left ears of two of the subjects tested, obtained response rates comparable to the response rates achieved by their right ears. However, the results also showed that the left ear on the third subject tested failed to compare with the response rate obtained by his trained right ear. It was suggested that this gave added support to the reported clinical observations, since out, of the three treatment subjects tested, one subject was found who could not respond with the left ear. It was concluded that a more intense investigation of the research problem be considered. Suggestions were also given in regards to improving the multiple-base- line design utilized in this study.
