This book was released on 2022-01-07 with total page 505 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basic Concepts of Clinical Electrophysiology in Audiology is a revolutionary textbook, combining the research and expertise of both distinguished experts and up-and-coming voices in the field. By taking a multidisciplinary approach to the subject, the editors of this graduate-level text break down all aspects of electrophysiology to make it accessible to audiology students. In addition to defining the basics of the tools of the trade and their routine uses, the authors also provide ample presentations of new approaches currently undergoing continuing research and development. The goal of this textbook is to give developing audiologists a broad and solid basis of understanding of the methods in common or promising practice. Throughout the text, individual chapters are divided into “episodes,” each examining a facet of the overarching chapter’s topic. With different experts handling each episode, readers are exposed to outstanding professionals in the field. This text singularly stitches together the chapters and their episodes to build from foundational concepts to more complex issues that clinicians are likely to face on their road to full clinical competency. As collections of episodes, the writers and editors thus endeavor to present a series of stories that build throughout the book, in turn allowing readers to build a broader interest in the subject. Key Features * Heads Up sections in each chapter introduce more advanced content to expose readers to what lies beyond the basic level and further enhance the main chapter content and “entertainment value” * Take home messages at the end of each chapter serve to focus the reader’s attention, encourage review, and discourage superficial learning by “just reading the abstract” * More than 450 innovative illustrations use combinations of panels, insets, and/or gray tone to facilitate reader understanding, optimize portrayal of data, and unify concepts across chapters * Numerous case studies and references to practical clinical issues and results are included throughout the book * Keywords are highlighted in-text to improve both attention and retention of critical terms and ease of returning to review them
Download or read book Human Auditory Evoked Potentials written by Terence W. Picton and published by Plural Publishing. This book was released on 2010-09-01 with total page 649 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews how we can record the human brain's response to sounds, and how we can use these recordings to assess hearing. These recordings are used in many different clinical situations--the identification of hearing impairment in newborn infants, the detection of tumors on the auditory nerve, the diagnosis of multiple sclerosis. As well they are used to investigate how the brain is able to hear--how we can attend to particular conversations at a cocktail party and ignore others, how we learn to understand the language we are exposed to, why we have difficulty hearing when we grow old. This book is written by a single author with wide experience in all aspects of these recordings. The content is complete in terms of the essentials. The style is clear; equations are absent and figures are multiple. The intent of the book is to make learning enjoyable and meaningful. Allusions are made to fields beyond the ear, and the clinical importance of the phenomena is always considered.

Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the use of the newest generation multiple auditory steady state responses (ASSRs) and auditory late responses (ALRs) in objective hearing threshold estimation in awake adults. A within-subject performance comparison between the 40 Hz ASSR and the ALR was conducted in 25 participants. Each participant was assessed monaurally using the Interacoustics Eclipse EP25. The test ear and order of testing were counterbalanced across participants. Stimuli centred at four test frequencies: 500, 1000, 2000 and 4000 Hz were presented via Eartone 3ATM insert earphones. The 40 Hz multiple ASSR used the narrowband (NB) CE-Chirp©, whilst the ALR used the long duration (80 ms) tone bursts. Note that for the ALR, 500 and 2000 Hz were prioritised, with the inclusion of 1000 and 4000 Hz if time and participant status permitted. The total test time for the 40 Hz ASSR to obtain a four-point audiogram was obtained by the time recorded on the software. The ALR test time was calculated in two forms: “actual” and “estimated”. The “actual” test time was calculated using the number of sweeps recorded for obtaining two frequencies (500 and 2000 Hz). The “estimated” time to obtain a four-point audiogram was calculated by doubling the “actual” time. Relative accuracy in estimating the behavioural audiogram was determined by comparing thresholds from each AEP measure. Results indicated comparable threshold estimates for 500 Hz, but statistically significantly lower (p
Download or read book Slow Cortical Auditory Evoked Potentials and Auditory Steady state Evoked Responses in Adults Exposed to Occupational Noise written by Leigh Biagio and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In individuals claiming compensation for occupational noise induced hearing loss, a population with a high incidence of nonorganic hearing loss, a reliable and valid behavioural pure tone (PT) threshold is not always achievable. Recent studies have compared the accuracy of behavioural PT threshold estimation using the slow cortical auditory evoked potentials (SCAEP) and auditory steady-state responses (ASSR) but there is no consensus regarding recommended technique. A review of the literature indicated that no comparison has been completed on the use of SCAEP and a single frequency ASSR technique. A research project was therefore initiated with the aim of comparing the clinical effectiveness (accuracy) and clinical efficiency (time required) of SCAEP and ASSR for behavioural PT threshold estimation in adults exposed to occupational noise. Adult participants were divided into a group with normal hearing (behavioural PT thresholds
Download or read book Threshold Estimation in Normal and Impaired Ears Using Auditory Steady State Responses written by Riette Bosman and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Auditory Steady State Response (ASSR) procedure has been established as a frequency specific, objective audiologic measure, which can provide reliable thresholds to within 10 dB of the behavioral thresholds. In order for ASSR to find its place in the existing framework of audiometric procedures, the full potential of the procedure needs to be explored. The aim of this study was to determine the accuracy of monotic ASSR in estimating hearing thresholds in a group of 15 normal hearing subjects and 15 hearing-impaired subjects. A comparative research design was implemented. Indicating that results obtained in the study was compared to relevant literature where dichotic multiple ASSR was implemented. This was done in order to ascertain ASSR's capabilities with regard to stimulus presentation methods. Monotic single ASSR predicted behavioural thresholds in the normal hearing subjects within an average of 24 dB across the frequency range (0.5, 1, 2 & 4 kHz). In the hearing-impaired group, ASSR thresholds more closely resembled behavioural thresholds, with an average difference of 18 dB, which is consistent with recent literature. The literature suggests that better prediction of behavioural thresholds will occur with greater degrees of hearing loss, due to recruitment. The focus in this group also centered on the accurate prediction of the configuration of the hearing loss. It was found that ASSR could reasonably accurately predict the configuration of the hearing loss. In the last instance, monotic single and dichotic multiple ASSR were compared with regard to threshold estimation and prediction of configuration of the hearing loss in the hearing-impaired group. Little difference was reported between the two techniques with regard to the estimation of thresholds in both the normal hearing and hearing impaired groups. In conclusion it was established that monotic ASSR could predict behavioural thresholds of varying degrees and configurations of hearing loss in normal and hearing-impaired subjects with a reasonable amount of accuracy. At this stage, however, more research is required to establish the clinical validity of the procedure, before it is routinely included within an objective test battery.
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.

Available in PDF, EPUB and Kindle. Book excerpt: Auditory steady-state responses (ASSRs) have been shown to be accurate in predicting thresholds of individuals with hearing loss. Although new stimuli are being proposed and clinically implemented, there are no data to indicate whether response interactions would be adversely affected by their use. This study investigated the effects of three different stimuli (AM, AM/FM and AM2) at two different intensities (60 dB HL and 80 dB HL) on response amplitudes and interactions in normal-hearing adults. Stimuli were generated by the Rotman MultiMASTER research system and presented via air conduction through EAR-3A insert earphones. Carrier frequencies of 0.5, 1, 2, and 4 kHz were 80-Hz modulated in three conditions: individually (monotic single; MS), simultaneously in one ear (monotic multiple; MM), and simultaneously in both ears (dichotic multiple; DM). It was predicted that stimuli with broader spectra would result in greater amplitudes. This was demonstrated in the MS condition by the AM/FM stimulus, which evoked responses significantly larger than those to both AM and AM2 stimuli at all frequencies except 0.5 kHz at 60 and 80 dB HL. In the multiple (MM and DM) conditions, response amplitudes to AM2 were significantly larger than AM and AM/FM response amplitudes at both intensities. It was also predicted that more interactions would be found when using stimuli with broader spectra, even at moderate intensities. This was illustrated by the drop in amplitude by the AM/FM stimulus in the multiple conditions versus in the single condition, even at 60 dB HL. Relative efficiency values in the multiple conditions were never less than that found in the single condition at 60 dB HL; at 80 dB HL, the majority (83%) of comparisons were more efficient in the multiple conditions than the single condition. Based on these results, the optimal stimulus to use appears to be dependent on the chosen condition. In the single condition, AM/FM stimuli result in the largest response amplitud.
