This book was released on 2018 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: A click-evoked Auditory Brainstem Response (ABR) was recorded on 28 normal hearing adult participants to determine the effects of different degrees of conductive hearing loss on the response properties of the ABR. Participants were divided at random into two groups: the normal hearing group and the simulated conductive hearing loss group. In the normal hearing group, baseline behavioral pure tone audiometry from 250-8000 Hz and acoustic immittance testing (tympanometry and contralateral acoustic reflex thresholds from 500-2000 Hz) were performed to ensure normal hearing and middle ear function. Then, ABR testing was performed in both right and left ears to click stimuli beginning at 80 dBnHL. Stimulus intensity was decreased in 10 dB increments until a stimulus intensity of 30 dBnHL was reached. At stimulus intensities less than 30 dB nHL, stimulus intensity was decreased in 5 dB increments until the participant's ABR threshold was determined. In the simulated conductive hearing loss group, baseline behavioral pure tone audiometry from 250-8000 Hz and acoustic immittance testing (tympanometry and contralateral acoustic reflex thresholds from 500-2000 Hz) were performed to ensure normal hearing and middle ear function. Then, 5 mm of moleskin was placed in the tubing for the ER3A insert receivers and pure tone air conduction thresholds were re-measured in each ear. For the conductive group, the ABR was recorded using the ER3A insert receivers with moleskin. The ABR was recorded in both right and left ears to click stimuli beginning at 80 dBnHL. Stimulus intensity was decreased in 10 dB increments until a stimulus intensity of 60 dBnHL was reached. At stimulus intensities less than 60 dBnHL, stimulus intensity was decreased in 5 dB increments until the participant's ABR threshold was determined. For both groups, results revealed an increase in the mean absolute latencies of waves I, III, and V as stimulus intensity decreased. In contrast, results showed a decrease in the mean peak-to-peak amplitudes for waves I-I' and V-V' as a function of stimulus intensity. Mean interpeak latency values were consistent across stimulus intensities. Mean absolute latency values for all waves were greater for the simulated hearing loss group than the normal hearing group. In contrast, the mean peak-to-peak amplitude values for waves I-I' and V-V' were smaller for the simulated hearing loss group than the normal hearing group. These results were compared to previous data collected in the ABR literature on both normal hearing and conductive hearing loss participants. Results for both groups in the current study were in good agreement with the ABR literature as seen in the mean ABR values and the variability represented by standard deviation measurements. The data collected from this study will be used to develop a parametric approach to generating simulated responses for the commercially available Auditory Brainstem Response (ABR) recording simulator, ISAO by Intelligent Hearing Systems. This data will serve as basis for developing functions of response characteristics such as peak latency and amplitude as well as recording parameters like intensity, rate and stimulus characteristics. Further research should be conducted to determine the effects of other stimulus parameters on the ABR. These stimulus parameters include rate, polarity, and frequency.

Available in PDF, EPUB and Kindle. Book excerpt: A recent study indicates that 20 million people in the United States have significant sensorineural hearing loss. Approximately 95% of those people have partial losses, with varying degrees of residual hearing. These percentages are similar in other developed countries. What changes in the function of the cochlea or inner ear cause such losses? What does the world sound like to the 19 million people with residual hearing? How should we transform sounds to correct for the hearing loss and maximize restoration of normal hearing? Answers to such questions require detailed models of the way that sounds are processed by the nervous system, both for listeners with normal hearing and for those with sensorineural hearing loss. This book contains chapters describing the work of 25 different research groups. A great deal of research in recent years has been aimed at obtaining a better physiological description of the altered processes that cause sensorineural hearing loss and a better understanding of transformations that occur in the perception of those sounds that are sufficiently intense that they can still be heard. Efforts to understand these changes in function have lead to a better understanding of normal function as well. This research has been based on rigorous mathematical models, computer simulations of mechanical and physiological processes, and signal processing simulations of the altered perceptual experience of listeners with sensorineural hearing loss. This book provides examples of all these approaches to modeling sensorineural hearing loss and a summary of the latest research in the field.

This book was released on 2009 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The auditory brainstem response (ABR) is an electrophysiological measure of hearing commonly used to detect hearing loss. Indeed, comparisons of ABR and behavioral thresholds have indicated that the two measures are, on average, highly correlated. However, recent research using rats has indicated that although the ABR may be correlated with behavioral measures of hearing, it does not reliably measure the degree of sensorineural threshold shift caused by exposure to loud sound. Considering these findings, the purpose of this study was to determine if the ABR can reliably estimate the degree of threshold shift caused by a conductive hearing loss. This was done by measuring the ABR and behavioral threshold shifts caused by placing an earplug in the ears of normal human observers. The results indicated that although the ABR was fairly accurate in estimating mean threshold shift for a group, it did not accurately estimate individual threshold shifts.

Available in PDF, EPUB and Kindle. Book excerpt: This volume will cover a variety of topics, including child language development; hearing loss; listening in noise; statistical learning; poverty; auditory processing disorder; cochlear neuropathy; attention; and aging. It will appeal broadly to auditory scientists—and in fact, any scientist interested in the biology of human communication and learning. The range of the book highlights the interdisciplinary series of questions that are pursued using the auditory frequency-following response and will accordingly attract a wide and diverse readership, while remaining a lasting resource for the field.
