Download or read book Frequency Specificity of Contralateral Suppression of Distortion Product Otoacoustic Emissions written by Lisa Arnelle Ross and published by . This book was released on 2013 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The frequency specificity of the contralateral suppression effect as demonstrated in DPOAEs was measured in 20 adult participants using contralateral stimuli consisting of white noise, and. 5, 1, 2, and 3 kHz tones with presentation levels of 40, 50, and 60 dB SPL. A significant suppression effect was found with white noise in the low frequencies (1.125 to 2.531 kHz) as well as higher frequencies (5.062 to 6.328 kHz). While not reaching a level of significance, 2 and 3 kHz demonstrated a similar suppression as white noise in the higher frequencies (5.062 to 6.328 kHz) and a non-significant enhancement effect was observed in the low frequencies (2.015 to 2. 812 kHz). Future studies of contralateral suppression should examine BBN with various high frequency cut offs in order to more fully examine these phenomenon.

Book excerpt: A new edition of a best-selling text with a CD-ROM by Dr. David Kemp The new edition of the best-selling Otoacoustic Emissions: Clinical Applications provides a thorough review of the complex physiology of the ear and clinical applications of the latest research on otoacoustic emissions. The book features new chapters on such important topics as middle ear function enhanced by reflectance measurements and the use of otoacoustic emissions as a preclinical measure of susceptibility to hearing loss. Accompanying the book is a CD-ROM developed by Dr. David Kemp, Ph.D., which contains animations, movies, and interviews. The CD-ROM serves as an indispensable aid to both teaching and reviewing key concepts. From physiological phenomena to diagnostic and clinical applications, this book is a complete reference on otoacoustic emissions that will provide graduates in audiology and residents in otolaryngology and otology with all the essential information needed for research and professional practice.
Download or read book The Efferent Auditory System written by Charles I. Berlin and published by Singular. This book was released on 1999 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Six studies explore how signals going from the brain to parts of the auditory system helps the system perform a number of functions, including adapting to background noise and allowing transients and other brief stimuli to be properly coded. Studies include discussions of the olivocochlear system and protection from acoustic injury, ontogenetic and evolutionary evidence for the motoneuron nature of vestibular and cochlear efferents, de-recruitment by multiband compression in hearing aids, and clinical applications. The CD contains a brief video of hair cell control and damping.
Download or read book Establishing the Test Retest Reliability of Contralateral Auditory Suppression of Transient Evoked Otoacoustic Emissions in a Cohort of Healthy Individuals written by Indika Pradeepa Kumari Gunasena Mahawattage and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In clinical practice, Transient Evoked Otoacoustic Emissions (TEOAE) are used to assess hearing impairments in several cohorts. The TEOAE can be evoked in healthy cochlea by presenting a brief auditory stimulus in the form of a series of clicks. Similarly, TEOAE signals can be suppressed in the ipsilateral ear by presenting an alternative sound to the contralateral ear through stimulation of either the medial olivo-cochlear (MOC) reflex or acoustic reflex (AR). The suppression effect results from either due to attenuation of the otoacoustic emissions generation through the activation of MOC reflex or due to the obliteration of their transmission by the activation of middle ear muscle reflex (acoustic reflex). In individuals that suffer from brain injury, such as a concussion, the neuronal pathways that enable CASTEOAE may be disturbed which in turn will restrict the ability to generate TEOAEs and to invoke the contralateral suppression effect. Moreover, since a person performing the test cannot manipulate TEOAE signals, the technique could provide an objective measure of concussion status and severity. The following study was designed to measure the test-retest reliability of the CASTEOAE as a first step in establishing the CASTEOAE phenomenon as an evaluation tool for concussion assessment. A convenience sample of 30 healthy individuals, 16-50 years of age completed the CASTEOAE test on two separate occasions, using a 14-day between test interval. The MOC reflex was activated using broadband noise of 60 dB SPL while the Acoustic Reflex was elicited by presenting a broadband noise of 80 dB SPL to the contralateral ear. The OAE amplitudes were recorded across 5 half octave bands in each ear. The test-retest reliability was estimated with the intraclass correlation coefficient procedure using a one-way random effects model for n=30, k (trials)=2. Confidence intervals for the Intraclass Correlation Coefficients (ICCs) and measures of homogeneity of variance were also calculated for each condition. The reliability estimates for CASTEOAE test scores were calculated for TEOAE scores with and without contralateral suppression (Primary measures) of the MOC reflex and separately for the acoustic reflex. The ICCs of the total OAE responses for both MOC reflex and acoustic reflex demonstrated as high as 0.9 in both ears and the ICCs of the fractional octave band for the MOC reflex ranged from 0.6 (left ear @1000 Hz) to 0.95 (right ear @ 4000 Hz), and 0.75 (left ear @1000 Hz) to 0.97 (right ear @ 4000 Hz) for the AR. This data suggests that the MOC and AR reflexes were each significantly repeatable upon test and retest in the sample. In addition, CASTEOAE suppression of the acoustic reflex was greater than MOC reflex suppression; and each participant showed unique TEOAE distribution pattern across the 5 half octave frequency bands, which were consistent over time. The results support the use of the CASTEOAE test as a reliable non-invasive approach to evaluate the functional status of the auditory efferent system and its neural connections with the rest of the brain and the use of this stable and objective measure as a clinical tool to assess a concussion injury.
