Vowel Production In Down Syndrome: An Ultrasound Study, Micalle Carl
Vowel Production In Down Syndrome: An Ultrasound Study, Micalle Carl
Dissertations, Theses, and Capstone Projects
The present study investigated the articulatory and acoustic characteristics of vowel production in individuals with Down syndrome (DS). Speech production deficits and reduced intelligibility are consistently noted in this population, attributed to any combination of phonological, structural, and/or motor control deficits. Speakers with DS have demonstrated impaired vowel production, as indicated by perceptual, acoustic, and articulatory data, with emerging evidence of vowel centralization. Participants in the study included eight young adults with DS, as well as eight age- and gender-matched controls. Ultrasound imaging was utilized to obtain midsagittal tongue contours during single-word productions, specifically targeting the corner vowels /ɑ/, /æ/, …

Otologic Blast Injuries, Michelle Singer
Dissertations, Theses, and Capstone Projects
The otologic system functions as a highly sensitive pressure transducer. Because of this, the ear is the most commonly affected organ in primary blast injury. Frequently encountered symptoms include hearing loss, tinnitus, and tympanic membrane perforations. The ear is repeatedly overlooked during triage and easily forgotten in subjects with multiple injuries after major catastrophic events such as explosions. This systematic review provides an overview of the most common otologic injuries observed after blast exposure in a variety of settings and populations. An analysis of 35 studies and an additional 23 reviews was performed in attempt to uncover patterns of otologic …
Associations Of The Medial Olivocochlear Reflex And Speech-In-Noise Abilities In Normal Hearing Adult Listeners: A Systematic Review, Imari J. Greaves
Associations Of The Medial Olivocochlear Reflex And Speech-In-Noise Abilities In Normal Hearing Adult Listeners: A Systematic Review, Imari J. Greaves
Dissertations, Theses, and Capstone Projects
This systematic review analyzed the research concerning the medial olivocochlear reflex (MOCR) and speech-in-noise abilities in normal hearing adult listeners. In an attempt to understand the underlying difficulties in this population, the following research questions were proposed: 1) Does the research indicate that the magnitude of MOC suppression measured via OAEs is related to a normal hearing subject’s ability to recognize speech-in-noise? 2) Are MOC effects measured via OAEs lateralized? Is there a right ear advantage as suggested by Khalfa, Morlet, Micheyl, Morgon & Collet (1997)? Ten studies met the standards for inclusion for this review. Analysis of the 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 …
