The Effects Of Various Modes Of Feedback On Preferred Ipod Listening Levels, Justine A. Mcdermott

Dissertations, 2014-2019

The current study was conducted in an effort to promote safe listening habits of personal media player device users. Devices such as the iPod are known to have high output capacities well within the range of potentially hazardous sound levels, thus there is a concern that personal listening may pose a risk to hearing. Intuitive and real-time feedback representing the risk of hearing damage based on selected Preferred Listening Levels (PLLs) was provided to subjects they listened to an iPod. Objective: To provide listeners with tools to judge ‘what is too loud’ (and potentially damaging to hearing) so that they …

The Effect Of Early Hearing Loss On Bobwhites’ Responses To Pure Tones: A Possible Animal Model Of Prelingual Deafness, Bethany Leanne Magee

Dissertations, 2014-2019

This study aimed to look at the behavioral responses of Bobwhite quail to pure tone stimuli by measuring peep suppression. We also considered if a duration of early hearing loss would affect Bobwhite’s responsiveness to the tones. Bobwhites were tested individually at all different ages post hatch day. The pure tones were presented at several different intensity levels and peep suppression was calculated as a measure of responsiveness to the stimuli. Mock trials were conducted as a measure of control to determine the birds’ typical peep rate. Some of the Bobwhite quail were injected with gentamicin 0-1 post-hatch day in …

The Acute Effects Of Gentamycin Ototoxicity On Bobwhite Quail Basilar Papilla And Auditory Brainstem Responses, Kristie Wilson

Dissertations, 2014-2019

The present study aimed to investigate the effectiveness of a single dose of gentamycin in elevating Auditory Brainstem Response (ABR) thresholds and causing inner ear hair cell loss or damage. A total of twenty-two Bobwhite quail were used (n=7 control, n=15 experimental); experimental group quail were injected with a 200 mg/kg dose of gentamycin within 24 hours of hatch (P0). Three to four days post-hatch or injection the quail underwent ABR testing. Thresholds were measured using a 1,000 Hz, 2,000 Hz, and 4,000 Hz tone pip and a click beginning at 90 dB nominalSPL. Resulting waveforms were analyzed using MATLAB …

Ultrasonic Vocalizations In Eph/Ephrin Mutant Mice, Bryna Rickenbach-Cline

Dissertations, 2014-2019

Purpose: Murine mammals, more commonly known as mice, emit ultrasonic vocalizations or “yelps” to communicate. It has been found that adult mice use these vocalizations to communicate with each other, and infant mice utilize ultrasonic vocalizations to communicate with their mother. It is known that a relationship exists between hearing ability and vocalization (Bass-Ringdahl, 2010). This study aims to record yelps/ vocalizations of four strains of mouse pups to determine how the development of hearing relates to the vocalizations that are emitted. It is thought that mice with compromised genes that encode for signaling proteins that are essential to the …

The Effects Of Musical Training On Perception And Neural Representation Of Temporal Fine Structure, Verleyne Andrews-Rodgers

Dissertations, 2014-2019

One of the most common complaints of persons with sensorineural hearing loss is difficulty hearing in background noise. Temporal fine structure (TFS) is one of the factors that contributes to understanding speech in the presence of background noise. TFS refers to the periodic information in speech which helps us to identify which speech sound we are listening to. TFS is also negatively affected by hearing loss, as well as age. In a quest to discover how TFS processing and thus speech-in-noise understanding can be improved, this study examined the effects of musical training on behavioral and physiological measures of temporal …

Quantifying Head Acceleration During Vestibular Rehabilitation, Anne Hogan

Dissertations, 2014-2019

Dizziness can often be a serious and confounding condition that ranges in severity from annoying to debilitating and affects many people. The most common and effective treatment for persistent dizziness is vestibular rehabilitation therapy, which falls into three categories: adaptation, sensory substitution, and habituation. While more is known about adaptation and sensory substitution, questions remain regarding the exact mechanisms of recovery for habituation. Precisely, the optimal stimulation to the vestibular system, as measured in intensity of head accelerations, is unknown for habituation treatment. In this dissertation are drafts of two manuscripts. The first explores the average intensity of linear and …

The Effects Of Auditory And Visual Distracters On The Toleration Of Background Noise In Normal Hearing Listeners, Lauren Shastany

Dissertations, 2014-2019

The primary objective of this study was to evaluate the effect of auditory and visual cognitive loads on the preferred background noise levels in normal-hearing listeners. This study investigated the preferable background noise levels (primary task) when normal hearing listeners were presented with auditory and/or visual cognitive distractions (secondary task). It was hypothesized that normal hearing listeners’ preferable background noise level would decrease in the presence of either distracter and that the synergistic effect of the two distracters would result in even lower preferable background noise level. Preferable background noise levels were measured on 24 normal-hearing listeners under four conditions. …

Effects Of Noise On Cognitive Function During Dual Tasks Across Normally Aging Adults, Jennine Harvey

Theses and Dissertations (ETD)

This study expands upon methods used to investigate cognition and speech perception which have been limited by lack of (a) pre-screening of cognitive function in participants, (b) reporting visual or auditory accuracy and reaction time measures across experimental conditions that examine reaction times, and (c) comprehensive test battery that includes performance across multiple levels of dual task paradigms (DTPs). This study aims to examine group performance on dual tasks (DT) increasing in cognitive (task difficulty) and perceptual load (noise) with age. Participants were divided into two groups based upon age. Group 1 consisted of 14 listeners (Female=11) who were 40-59 …

Treatment Of Stuttering In Children: Clinician Perceptions Of Therapy Approaches, Kolbee Gilmore

Rehabilitation, Human Resources and Communication Disorders Undergraduate Honors Theses

The purpose of this study was to investigate the range of therapy approaches used to treat children who stutter in order to determine if there was a trend for clinicians to use technological devices rather than verbal methods. The questions of the study included the frequency at which each approach was used, whether or not the results differed based on the approach used, whether developmental age group was a factor regarding results, and the clients’ opinions on each approach. A brief survey was electronically distributed to 100 speech-language pathologists who have conducted therapy using either of the two approaches. The …

Self-Reported Symptoms Of Central Auditory Processing Dysfunction Following Mild Traumatic Brain Injury, Devon Beebe

Renée Crown University Honors Thesis Projects - All

Mild traumatic brain injury (mTBI), also known as concussion, has emerged as a major public health concern in the United States and worldwide. Of the estimated 1.7 million head injuries that occur nationally each year, about 75% are mTBI. Despite the “mild” label, a significant percentage of these individuals continue to experience a wide array of life-altering physical, emotional, and cognitive post-concussion symptoms for months and years following injury. The central auditory nervous system is vulnerable to several injury mechanisms in TBI and, as a result, auditory problems can be among these long term problems.

Although evidence of auditory processing …

Aerodynamic And Acoustic Features Of Vocal Effort, Allison Rosenthal

Speech-Language Pathology - Theses

Many voice disorders are associated with an effortful voice; however, there have been very few studies that have examined the physiological changes that contribute to this sense of effort. Determining the factors that contribute to change in vocal effort may help clinicians to effectively target these variables when working with people with voice disorders so that voice improvement is accompanied by decreased vocal effort after treatment. Prior research has shown that alterations in aerodynamic and acoustic variables are often associated with voice disorders involving increased muscular effort, and change in these variables is correlated with abnormal voice qualities. The current …

I tackle voice from a multi-dimensional approach integrating research and clinical practice. What follows is based on extensive research that I have reviewed over the years, on coursework that I have taught in related areas (including anatomy and physiology of speech, language and hearing; phonetics, linguistics, and neurological bases of speech, language and hearing) and on my own experience as a licensed speech language pathologist who has diagnosed and treated patients …

Gait Analysis Of Teenagers And Young Adults Diagnosed With Autism & Severe Verbal Communication Disorders, Michael J. Weiss, Matthew F. Moran, Mary E. Parker, John T. Foley

All PTHMS Faculty Publications

Both movement differences and disorders are common within autism spectrum disorders (ASD). These differences have wide and heterogeneous variability among different ages and sub-groups all diagnosed with ASD. Gait was studied in a more homogeneously identified group of nine teenagers and young adults who scored as “severe” in both measures of verbal communication and overall rating of Autism on the Childhood Autism Rating Scales (CARS). The ASD individuals were compared to a group of typically developing university undergraduates of similar ages. All participants walked a distance of 6-meters across a GAITRite (GR) electronic walkway for six trials. The ASD and …

A Comparison Of Caregiver And Speech-Language Pathologist's Ratings Of Speech Outcome In Oral Cleft Clinic, Emily Swain

Honors Theses

Background: Cleft lip and/or palate is one of the most common congenital anomalies. The goal of treatment of cleft palate is normal speech, but a proportion of children with clefts exhibit speech disorders. Various outcome measures are used, but relatively few have focused on self-assessment or caregiver perception of outcome. The studies that have been done focus on comparing parents' and speech-language pathologists' ratings of speech outcome. These studies can be used to determine the degree to which caregivers are satisfied with speech outcome over time.

Purpose: The purpose of this study was to describe the relationship between speech ratings …

The Measurement Of Auditory Interhemispheric Transfer Time (Ihtt) In Children With Normal Auditory Processing Abilities, Brittany Suzanne Keahey

Doctoral Dissertations

Interhemispheric transfer time (IHTT) is the time it takes for information to be transmitted from one hemisphere to the other. The goal of this study was to determine if differences existed in the IHTT of children 6 to 9 years of age with normal auditory processing abilities by the use of an objective measure (auditory late evoked potentials [ALEPs]), specifically waves P1, N1 and P2. It was hypothesized that there would be no difference in IHTT between the groups due to the age range of participants being tested. The 16 participants were divided into two groups based on age and …

Asymmetrical Speech In Noise Assessment For Children With (Central) Auditory Processing Disorders, Jessica Vaughn

Doctoral Dissertations

The primary purpose of this investigation was to determine if children with (Central) Auditory Processing Disorder have better word recognition abilities for monosyllabic words under monaural speech-in-noise conditions than binaural speech-in-noise conditions. Fifteen participants, five females and ten males, ages 8-10 years, were included in this study. There were 7 children placed in the experimental group with a diagnosis of (C) APD identified from the Louisiana Tech University Speech and Hearing Center. There were 8 typically developing children placed in the control group. Each participant had pure-tone thresholds of 0-20 dB HL for 250-8000 Hz bilaterally. The SCAN-3 for children, …
