Development Of Realistic Stimuli For The Evaluation Of Listening Effort Using Auditory Evoked Potentials, Christie Hoo Yee Leung

Dissertations, Theses, and Capstone Projects

Purpose – Listeners often report difficulty perceiving speech in background noise, such as when listening in a restaurant. A common complaint of difficulty perceiving speech in noisy restaurants leads to the development of the present study, where audio recordings of connected discourse mixed with restaurant noise at different signal-to-noise ratios were made to determine the effect of restaurant noise on listening effort. Listening effort has previously been examined with psychophysiological measures, a dual-task paradigm, and qualitative measures using a variety of auditory stimuli ranging from simple tonal stimuli to complex speech stimuli, such as consonant-vowel syllables, words, and full sentences, …

Audiometric Status, Self-Perception Of Hearing Disorders, And Noise Dose In Audio Post-Production Engineers, Laura M. Sinnott

Dissertations, Theses, and Capstone Projects

Numerous studies have assessed the risk of hearing injury for musicians and other sound professionals due to excessive sound exposure, however no studies have investigated whether audio post-production engineers have this same risk. This preliminary study first measured 23 participants’ hearing thresholds and prevalence of audiometric notches. Second, a questionnaire, the Questionnaire for Sound Professionals (QUSP), was designed and administered to determine whether correlations between audiometric status and self-perception of hearing loss and hearing disorders existed. Third, sound dosimetry measurements were conducted at film audio post-production studios to assess whether this population is at risk for permanent hearing loss due …

Individual Differences In Stimulus Frequency Otoacoustic Emission Phase, Joshua J. Hajicek

Dissertations, Theses, and Capstone Projects

Otoacoustic emissions (OAEs) are sounds that originate in the cochlea and are measured in the ear canal. OAEs provide a noninvasive tool for investigating cochlear mechanics. Stimulus-frequency OAEs (SFOAEs) are evoked by presenting a single frequency tone, called a probe tone, which have an advantage over other OAEs because they are the least influenced by cochlear nonlinearities. However, because the SFOAE are generated in the cochlea with the same frequency as the stimulus, additional techniques, such as the use of suppressor tones are needed to enable separation of the probe tone from the SFOAE.

The primary goal of this investigation …

The Effects Of Dance Therapy On Voice In Patients With Parkinson's Disease In A Multicultural Population, Ivon N. Ramirez

Theses and Dissertations

Current literature suggests that dance therapy in individuals with Parkinson’s disease shows noticeable improvement in motor functions, for example gait and balance improvement. Additionally, patients with Parkinson’s disease who participate in dance therapy may perceive positive benefits on their quality of life. Therefore, it is believed that increases in core support and improvements in posture, as a result of dance therapy, will have effects on the voice in patients with PD.

This thesis pulls from literature supporting treatment approaches in the field of speech-language pathology for voice patients with Parkinson’s disease. The aim of this study was to evaluate the …

Ethnographic Insight Into The Developmentally Diverse Worlds Of Twins: “L & J”, Allison Gallant

Senior Honors Projects

According to the National Institute of Deafness and Other Communication Disorders (2016), approximately 3 of every 1000 infants are born with a detectable level of hearing loss in one or both ears: with 90% of these infants being born to hearing parents. Immediately following the birth of a deaf child, parents are often bombarded with decisions regarding interventions to “fix” their child’s “disability”. This decision can impact how their child will experience the world and others. The situation is a very different stressor when a hearing child is born to deaf parents. Embracing one’s deaf identity and engaging in “deaf …

Decibel Levels And Employee Perceptions Of Noise Levels In Child Care Facilities, Emily K. Pope

Honors Program Theses and Projects

This quantitative study investigated decibel levels and employee perceptions of the noise levels in four child care facilities. Using a sound level meter, the decibel levels of each facility were measured when the rooms were unoccupied and when they were unoccupied and, information about the acoustic environment was collected. Employees (n= 22) completed a survey rating noise levels during activities throughout the day and the potential implications of the noise levels on their voice and hearing. Results showed that the child care facilities adhered to OSHA standards for permissible noise in work environments (90dBA for 8 hours). The sound-level measurements …

Promoting Aphasia Awareness, Yvonne M. Faria, Fiona Mcnulty, Veronica C. Gonzalez, Peggy S. Conner

Publications and Research

The National Aphasia Association defines aphasia as an impairment of language, affecting the production or comprehension of speech and ability to write. This communication disorder is typically acquired after a brain injury resulting from an accident or stroke. Nearly 180,000 Americans acquire aphasia each year. Despite efforts to increase awareness about aphasia, via organizations such as the National Aphasia Association, general knowledge is still limited. In 2000 Elman and colleagues collected data on the number of news articles that mentioned the term “aphasia” and compared it to similar health conditions with comparable or lower prevalence rates. They found that these …

Examining Social Pragmatic Communication: Evidence From Parent And Professional Questionnaires, Katelyn Adams

Honors Theses

Hyter (2007) defined pragmatics as “daily interactions among groups of people with varying worldviews, each influenced by a history of social practices” (p.131). People use aspects of pragmatics in their everyday life depending on the context of their current social situation. For example, one’s pragmatic language could differ in a day from talking with a boss at work to having a conversation with a friend on the phone. These variations in conversational processes result in the assessment of pragmatics being a difficult task.

In this honors thesis, I examined results from Dr. Yvette Hyter’s assessment battery, the Assessment of Pragmatic …

Speech Naturalness Before And Following Treatment In Adults Who Stutter, Alexis Novelli

Honors Theses

Purpose: The speech of persons who stutter can often sound unnatural. This can be due to a variety of factors including the presence of stuttering itself and/or the unintended consequence of speech-altering treatment. Understanding factors that contribute to speech naturalness within the stuttering population can direct improved management approaches. This study examines associations between speech task, behavioral measures of stuttering, and selected acoustic measures on listener ratings of speech naturalness for a group of adults immediately before and after participation in an intensive fluency-shaping treatment program. A secondary aim of this study is to assess the use of a novel …

The Dixit Method Of Language Sampling In Early Adolescence, Tanner Smith

Masters Theses & Specialist Projects

The current study examined two methods of language sampling (interview and the Dixit Method) in early adolescents with typical language development. The purpose of this study was to examine the effectiveness of the two procedures in eliciting lexical diversity in spoken language samples in the early adolescent population. To examine lexical diversity, traditional methods of analysis (type token ratio, average type token ratio, and mean length of utterance) were applied. However, because literature historically alludes to flaws in these traditional methods, the researchers also applied an ecological approach to analysis of lexical diversity proposed by Scott Jarvis (2013). Student participants …
