A Case Study Of Cochlear Implants And Complications, Carly E. Amurao

Senior Honors Projects

A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear, allowing the individual access to sound. In recent years, there has been tremendous progress in developing technology in the area of cochlear implants to aid those with severe/profound hearing loss. Specifically, there has been a movement towards bilateral implantation. Each cochlear implant candidate has a unique hearing loss, and must reach required bench marks in order to be considered a viable candidate for a cochlear implant. This process includes: meeting the required level of hearing loss, a required trial with hearing aids that …

Musical Training Influences Auditory Temporal Processing, Saravanan Elangovan, Nicole Payne, Jacek Smurzynski, Marc A. Fagelson

ETSU Faculty Works

Background: A link between musical expertise and auditory temporal processing abilities was examined.

Material and methods: Trained musicians (n=13) and non-musicians (n=12) were tested on speech tasks (phonetic identification, speech recognition in noise) and non-speech tasks (temporal gap detection).

Results: Results indicated musicians had shorter between-channel gap detection thresholds and sharper phonetic identification functions, suggesting that perceptual reorganization following musical training assists basic temporal auditory processes.

Conclusions: In general, our results provide a conceptual advance in understanding how musical training influences speech processing, an ability which, when impaired, can affect speech and reading competency.

Tinnitus And Trauma, Marc A. Fagelson

ETSU Faculty Works

Trauma-provoked tinnitus challenges patients and clinicians. Effects of trauma may exacerbate tinnitus, and patients with both tinnitus and posttraumatic stress disorder rate distress levels as higher than patients who experience only one or the other. This presentation will highlight links between tinnitus and trauma histories relevant to clinical audiologists.

Counseling Training For Audiology Students: Using Standardized Patients, Catherine Schroy

Arts & Sciences Graduate Student Theses and Dissertations

The implementation of Universal Newborn Hearing Screening (UNHS) has resulted in earlier diagnosis of hearing loss in children. Research shows that early diagnosis of hearing loss results in better outcomes in speech and language, socio-emotional, and cognitive development. Early diagnosis, however, often comes as a surprise to parents of newborns. When parents are told their child has a hearing loss, it is often before they have been able to observe behaviors that would lead to the suspicion of hearing loss. Parents are usually told about the hearing loss diagnosis by an audiologist and are often dissatisfied with how the news …

Pre-Pulse Inhibition Assessment Of Sound Localization In Mice, Kathryn C. Brooks

Senior Honors Projects, 2010-2019

The purpose of my Honors Research Project was to assist Dr. Megan

Klingenberg in completing part of the research in her final dissertation project. Dr.

Klingenberg’s project was based off of a study done by Allen and Ison in 2010.

This study tested the auditory spatial acuity of mice using pre-pulse inhibition of

the startle reflex as the response for detecting the sound stimulus. The goal of

Dr. Klingenberg’s AuD project was “to explore the methodological, functional, and

genetic influences on sound localization using pre-pulse inhibition of the acoustic

startle response in mice”. Dr. Klingenberg’s project was broken into three …

Binaural Listening In Young And Middle-Aged Adults: Interaural Phase Differences And Speech-In-Noise Measures, Caitlin Cotter

Dissertations, 2014-2019

Difficulty understanding speech in the presence of noise is a common complaint of middle-aged and older adults with and without hearing loss. There is an incomplete picture of what contributes to difficulties understanding speech-in-noise in adults who have normal audiograms. As humans we listen binaurally, so declines in binaural processing may contribute to speech-in-noise difficulties. We examined the effects of age on the upper frequency limit of interaural phase difference (IPD) detection and IPD detection at fixed frequencies. We also examined a speech-in-noise measure of spatial separation across young and middle-aged, normal-hearing individuals.

Participants were young (n=12) and middle-aged (n=8) …

Effects Of Auditory And Visual Distracters On Acceptable Background Noise Level In Hearing-Impaired Listeners, Elizabeth A. Ripley

Dissertations, 2014-2019

Acceptable Noise Level (ANL), is an established procedure for determining the amount of background noise a listener is willing to accept while listening to speech. ANL is established by having the listener select most amount of background noise they are willing to accept while listening to a speech stimulus presented at their most comfortable listening level (MCL). While ANLs have been established as good predictors of hearing aid use, little is known on how hearing aid users accept background noise while engaged in cognitively demanding tasks. Previous research in normal hearing listeners has demonstrated that listeners will allow the most …

Hearing Loss In The Dental Office: The Effects Of High Speed Dental Drills On Dentists' Hearing, Krisztina Johnson, Jacek Smurzynski, Saravanan Elangovan, Marc Fagelson

ETSU Faculty Works

Hearing test results of 23 dentists obtained before and after working hours are compared to determine if dentists experience any temporary hearing loss. The aim of the project is to determine whether dental drills cause hearing loss and to document the consequences of the loss. Hearing evaluations include pure-tone audiometry, middle-ear testing, and measurements of otoacoustic emissions. The results are expected to convince dentists of the danger of noise exposure and the need for hearing protection

The Effect Of Dialect On Speech Audiometry Testing, Shawn L. Nissen, Richard W. Harris, Ron W. Channell, Nathan E. Richardson, Jamie A. Garlick, Dennis L. Eggett

Faculty Publications

Purpose: In this study, the authors examined the validity of using materials from 2 nonregional yet mutually intelligible dialects to evaluate an individual’s speech recognition threshold (SRT) and word recognition (WR) abilities and whether a speaker of 1 dialect could accurately administer and score materials in the other dialect. Method: Previously created SRT and WR materials were presented to 32 Mandarin listeners with normal hearing:16 speakers of Mainland Mandarin and 16 speakers of Taiwan Mandarin. Hearing abilities were examined using SRT and WR materials created for speakers from 2 different regional dialects. Presentation of the materials occur red during 2 …

Military Trauma And Its Influence On Loudness Perception, Marc A. Fagelson

ETSU Faculty Works

Excerpt: It is often the case that veterans who experience hyperacusis have hearing loss and tinnitus; what sets the patient with PTSD apart is an increased likelihood that will rate sound tolerance problems as more severe than tinnitus and hearing loss.

Psychometrically Equivalent Monosyllabic Words For Word Recognition Testing In Mongolian., Valarie Nicole Haslam

Theses and Dissertations

The purpose of this study was to record a set of Mongolian monosyllabic word lists that could be used to obtain a word recognition score. A word list was developed of 190 frequently used monosyllabic words which had been selected by a group of raters. Native male and female Mongolian talkers were utilized to make digital recordings. The 190 words were divided into 10 lists of 19 words. The lists were presented to 20 normally hearing subjects at 10 different intensity levels ranging from -5 to 40 dB HL in 5 dB increments. An S-curve distribution was used to divide …

The Effect Of Using Averaged Versus Custom Real-Ear To Coupler Difference Values In The Desired Sensation Level Approach To Prescribing Hearing Instrument Gain, John Aaron Coverstone

Dissertations and Theses

Because there are many variables and much missing information when fitting young children with hearing instruments, it is necessary to rely on prescriptive procedures such as the Desired Sensation Level (DSL) Method to create target 2cc gain values for ordering and fitting hearing instruments. Inherent in creating 2cc targets is a conversion process known as a real-ear to coupler difference (RECD) measurement. The DSL algorithms make allowances for averaged data to be used in lieu of this measurement.

The purpose of this study is to evaluate the validity of using averaged real-ear to coupler difference values included in the DSL …
