This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Multiple Auditory Steady-State Response (MASTER) technique enables the rapid and objective assessment of hearing by statistically evaluating electrophysiological responses evoked by multiple tones which are presented simultaneously. The technique offers several advantages over transient stimuli techniques used to assess hearing. Firstly, since eight stimuli may be presented simultaneously, in the time normally required to evaluate one stimulus, MASTER provides a relatively rapid assessment of hearing. Secondly, the stimuli are more frequency specific than transient stimuli since steady-state stimuli contain spectral energy only at the carrier frequency and at the sidebands, which occur at spectral frequencies equal to the difference between the carrier and modulation frequency. Lastly, the technique reduces the necessity for expert evaluation of a subject's responses since these are evaluated objectively, statistically, and automatically by a computer program. The experiments presented here build upon the original work on the technique that occurred only a short time ago (Lins, 1995), and serve to form a sufficient foundation for the technique to start to be evaluated as a viable clinical tool. Chapter 1 demonstrates some limitations of the technique that should be considered when designing test stimuli. For example, in order to insure that simultaneously presented stimuli do not interact, they should be separated by at least one octave in normal hearing subjects. Chapter 2 provides a description of the theory, design, and implementation of a Windows based data acquisition system. In Chapter 3 the use of both amplitude and frequency modulated stimuli is examined. We show that by using both of these types of modulation the technique is more efficient, even at threshold intensities. In Chapter 4, the phase values of the responses are examined and a technique is proposed for accurately converting phases into latencies. As with amplitude, steady-state phase values are stable over time, show changes with intensity that are similar to those seen with transient stimuli, and are unchanged by the presentation of multiple stimuli. The work presented here suggests the MASTER technique can function as a useful clinical tool in objective audiometry, and suggests several directions that may be useful for future research.

Download or read book Mechanisms and Dynamics of the Human Auditory Steady state Response written by Daniel J. Bosnyak and published by . This book was released on 2003 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiment 1 investigated how auditory evoked potentials change as stimulus rate increases from the transient to the steady state range. Only the 13 Hz response-produced a frequency-amplitude characteristic with a prominent peak in response amplitude at 40 Hz. A new signal processing procedure, based on the Hotelling T2 statistic but applied in a procedure similar to a spectrogram, was used to show dynamics in the steady-state response which were not observable in the time-domain averages.
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.
Download or read book Auditory Brainstem Evoked Potentials written by Ananthanarayan Krishnan and published by Plural Publishing. This book was released on 2021-10-06 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Auditory Brainstem Evoked Potentials: Clinical and Research Applications provides a solid foundation of the theoretical principles of auditory evoked potentials. This understanding is important for both the development of optimal clinical test strategies, and interpretation of test results. Developed for graduate-level audiology students, this comprehensive text aims to build a fundamental understanding of auditory evoked brainstem responses (ABR), and their relationship to normal and impaired auditory function, as well as its various audiologic and neurootologic applications. In addition to covering the classical onset ABR, the book provides a thorough review of sustained brainstem responses elicited by complex sounds, including auditory steady state response (ASSR), envelope following response (EFR), and frequency following response (FFR), and the growing clinical and research applications of these responses. By exploring why certain stimulus manipulations are required to answer specific clinical questions, the author provides the resources needed for students and clinicians to make reasoned decisions about the optimal protocol to use in a given situation. Key Features: * A full chapter devoted to laboratory exercises * Numerous illustrations to help explain key concepts * Description of neural bases underlying amplitude and latency changes * Troubleshooting techniques * End-of-chapter summaries

Download or read book Ringing ears the neuroscience of tinnitus written by Jos J. Eggermont and published by Frontiers E-books. This book was released on with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tinnitus (ringing in the ears) is a prevalent and often debilitating disorder with approximately 10% of people (incorporating ages from children to the elderly) perceiving it continuously, and in 1-3% of the population it seriously affects the quality of life. The most common cause of tinnitus is hearing loss, and its prevalence has surged as a result from the various large-scale military actions in the Middle East in the last decade. Recent advances have been made in the area of behavioral animal models, in the understanding of human brain imaging aspects of tinnitus, and in addressing the long-range changes in human brain connectivity. Furthermore continued exploration of the three major animal models of tinnitus: salicylate-induced, noise trauma induced, and resulting from somatic interactions with the auditory system has further delineated the relative roles of cochlear activity vs. central auditory system changes. Evidence for the role of neural synchrony changes in tinnitus originates both from human EEG and MEG studies as well as from neuron pair-correlation studies in animals.

Download or read book Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

Download or read book Accuracy of Auditory Steady State Response ASSR for Prediction of Behavioral Pure tone Thresholds written by Ryan Potter and published by . This book was released on 2013 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study attempted to determine the most appropriate clinical protocol for using the Auditory Steady-State Response for the prediction of pure tone behavioral thresholds. Behavioral and Auditory Steady-State Response thresholds were measured at 500 - 4000 Hz from sixteen normal-hearing subjects. All subjects were tested using both the single-frequency ASSR test approach as well as the multiple-frequency ASSR test approach in an attempt to determine which approach was the most accurate predictor of behavioral pure-tone thresholds. Additional test parameters, such as the EEG recording channel (ipsilateral versus contralateral) and overall test duration were evaluated in order to determine the most appropriate clinical protocol for obtaining Auditory Steady-State Response thresholds. The results of this study revealed that using a combination of the multiple-frequency ASSR test approach to initially bracket threshold and the single-frequency ASSR test method to better define threshold would most likely yield the most accurate estimation of pure-tone behavioral thresholds in the most acceptable amount of time. The study also determined that a two channel recording (ipsilateral and contralateral) should be employed to yield the most sensitive ASSR thresholds.
