Download or read book Early Detection of Music induced Hearing Loss Through a Comparison of Transient Evoked and Distortion Product Otoacoustic Emission Data Among University Music and Non music Majors with Normal Hearing written by Chere Fourie and published by . This book was released on 2017 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Otoacoustic emission (OAE) tests are clinically valuable measures of peripheral auditory function. Early detection of music-induced hearing loss was the focus of this study to determine if musicians are at a greater risk of cochlear dysfunction due to their frequent exposure to loud sounds compared to non-exposed individuals. This study was designed to explore any significant differences between pure tone audiometry, OAE testing, and auditory side effects among non-music and music major university students with normal hearing. Tinnitus was found in all subgroups, except male music majors who did not report any tinnitus symptoms. Results suggested a relationship between better hearing sensitivity and cochlea function with lack of tinnitus. No ear effects were found among the different testing measures. However, music majors were found to have higher DPOAE SNR thresholds compared to their non-music peers, indicating musical experience did not lead to testing decreases. The effects of recreational music usage was explored as a potential risk factor for both music and non music majors. Suggestions for future research include using larger sample sizes and monitoring hearing abilities in noise exposed population due to increase of recreational music exposure.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Transient-Evoked Otoacoustic Emissions (TEOAE) are nonstationary acoustic signals coming from the inner ear after acoustic stimulation by clicks and they are applied as tools in newborn hearing screening programs to allow the early identification of hearing loss and the consequent diagnosis and intervention. In any screening program, the duration of each test is a crucial parameter. For TEOAE, it is strongly influenced by the acquisition procedure, typically based on classical synchronous averaging technique over 260 sweeps, with an average acquisition time of about 2-3 minutes. This paper present an application of Principal Component Analysis (PCA) to rapidly-acquired TEOAE (averaged over only 10, 60 or 100 sweeps) for the detection of this type of cochlear response. The PAC approach is shown to be able to enhance the signal-to-noise ratio (SNR) and, in turn, to allow a correct detection of the responses. Results of the application of this approach in comparison with responses recorded, from the same wars, with classical technique will be shown. The reduction of the acquisition time to about one fourth with respect to its typical value and with approximately the same final signal-to-noise ratio will be discussed.

Download or read book Schuknecht s Pathology of the Ear written by Saumil N. Merchant and published by PMPH-USA. This book was released on 2010 with total page 970 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a dedicated text to learn pathologic images seen during EUS. The digital anatomy correlation used in this work is the natural continuation of efforts to apply the University of Colorado Visible Human data set to gastroenterology. The Visible Human data set was created by Dr. Vic Spitzer and colleagues at the University of Colorado and is currently housed at the universitys Center for Human Simulation. The data set consists of high resolution transaxial digital images captured as cadavers were abraded away at 1 mm or less depths. These images are compiled into blocks of data and each structure is identified. This information can be used to pull out and manipulate 3-D structures as well as allowing one to review planar anatomy in any orientation. Using the Visible Human dataset, one should be able to find a normal anatomy correlate to any image found during a EUS examination. However, as important as normal anatomy is, it is the abnormal features which are the crux of an EUS examination. Endosonographers are asked to define lumps, bumps, cysts to find correlates for symptoms and abnormal laboratory findings. Accuracy requires a tremendous amount of skill and experience. To help in this task, we have assembled chapters from a world-wide group of expert endosonographers. These authors have shared their insight and images to help the readers of this work better see and understand some of the complexities uncovered during a EUS evaluation.
