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.

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 …

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

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 …

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 …

Lexical Access In Individuals With Cerebral Palsy And Severe Speech And Physical Impairment, Iris Fishman

Dissertations, Theses, and Capstone Projects

This study examined lexical access in adolescents and adults with cerebral palsy and severe speech and physical impairment (CP/SSPI) who have limited language production due to severe dysarthria or anarthria. To date, the impact of a severe speech production deficit on lexical activation and the organization of the mental lexicon has not been investigated. Such an investigation may support or refute these views of an articulatory basis of speech perception and lexical development and access. The hypothesis of this study is that spoken word recognition will be severely reduced or absent in this population although individual differences may result in …

Perception Of American–English Vowels By Early And Late Spanish–English Bilinguals, Miriam Baigorri, Luca Campanelli, Erika S. Levy

Publications and Research

Increasing numbers of Hispanic immigrants are entering the US and learning American–English (AE) as a second–language (L2). Previous studies investigating the relationship between AE and Spanish vowels have revealed an advantage for early L2 learners for their accuracy of L2 vowel perception. Replicating and extending such previous research, this study examined the patterns with which early and late Spanish–English bilingual adults assimilated naturally-produced AE vowels to their native vowel-inventory and the accuracy with which they discriminated the vowels. Twelve early Spanish–English bilingual, 12 late Spanish–English bilingual, and 10 monolingual listeners performed perceptual-assimilation and categorical-discrimination tasks involving AE /i,ɪ,ɛ,ʌ,æ,ɑ,o/. Early bilinguals …

Cognitive And Neurobiological Degeneration Of The Mental Lexicon In Primary Progressive Aphasia, Jet M. J. Vonk

Dissertations, Theses, and Capstone Projects

The ease with which we use the thousands of words in our vocabulary stands in stark contrast to our difficulty establishing how they are organized in our mind and brain. The breakdown of language due to cortical atrophy in primary progressive aphasia (PPA) creates conditions to study this organization at a cognitive and neurobiological level in that the three variants of this disease, namely non-fluent, logopenic, and semantic PPA, each bear their own signature of language-specific decline and cortical atrophy. As the impaired regions in each variant are linked to different lexical and semantic attributes of words, lexical decision performance …

Occlusion Effects In Various Testing Conditions Using Insert Earphones, Amanda M. Desantolo

Dissertations, Theses, and Capstone Projects

The occlusion effect is a well-known phenomenon that can affect audiological testing. Sound energy that would typically escape is trapped when covering the ear(s) and reflected back toward the inner ear. This increases the intensity of the sound, resulting in the “appearance” of a more sensitive threshold. Many aspects of the occlusion effect have been well researched and understood, however there are still aspects that warrant further investigation, such as the degree of occlusion with insert earphones when using partial versus full insertion and whether one or both of the ears are occluded. A within-subject design (n=5) was utilized to …

Recreational Music Exposure And Music-Induced Hearing Loss: A Systematic Literature Review, Carolyn Lindenbaum

Dissertations, Theses, and Capstone Projects

Legislation regarding occupational noise exposure is the result of a long period of interest and research; more recently, the effects of recreational noise are receiving increasing attention. Various sources of recreational noise and music exposure have become more widespread among the general public, increasing research in this source of potential risk. The proliferation of personal music players that are easily available and accessible to children and adults has contributed to the spread of leisure music exposure. Leisure music exposure is also common in the attendance of concerts and clubs/discos, and bars/pubs. The present systematic literature review focused exclusively on recreational …

A Systematic Review Of Occupational Music-Induced Hearing Loss, Lilach Gez Saperstein

Dissertations, Theses, and Capstone Projects

The prevalence of noise induced hearing loss (NIHL) is a public health concern with government regulations (i.e. OHSA, NIOSH) in place to protect employees in occupational settings. Sound pressure levels (SPL) of various industries have been measured and exposure dosages monitored as per the national regulations. Previous research has demonstrated that occupational exposure to loud noise has led to audiometric evidence of NIHL. Thus, it raises the question about the impact of occupational exposure to music on hearing. For the purposes of this capstone, literature pertaining to occupational music exposure levels, and the effects on both hearing threshold levels and …

Development Of 90th Percentile Norms For Ipsilateral Acoustic Reflex Thresholds: A Feasibility Study, Iris Wertheimer

Dissertations, Theses, and Capstone Projects

The acoustic reflex threshold has been well established in the literature as an involuntary bilateral contraction of the stapedius muscle in response to loud transient sounds. Additionally, the clinical utility of the acoustic reflex threshold has been established as it allows for the differential diagnosis of many different conductive, cochlear and retrocochlear pathologies. Gelfand, Schwander and Silman (1990) have established and validated 90^th percentile normative data for use with the contralateral acoustic reflex threshold. Much of the literature on the acoustic reflex threshold has focused on the contralateral acoustic reflex threshold; however, surveys have found that many clinicians are …

Dissertations, Theses, and Capstone Projects

The objective of this systematic review was to determine the methods in which postural stability and control are being quantified in persons with Autism Spectrum Disorder (ASD), with what instrumentation and which healthcare professionals are included in this process. It is well studied that persons with Autism Spectrum Disorder (ASD), which now include those with Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) and Asperger Disorder, often suffer from vestibular modulation abnormalities (Rogers & Ozonoff, 2005; American Psychiatric Association, 2013.) These individuals may present with either an under- or over-responsiveness to vestibular inputs resulting in a variety of repetitive behaviors or …

"Marie Manje La Pom Nan." Examining The Cognitive Process Of Restructuring And Advantage Selection In The Definite Article System In Haitian Creole Among U.S. Born Heritage Speakers Of Haitian Creole, Marie-Michelle Monéreau-Merry

Dissertations, Theses, and Capstone Projects

The distributional patterns of heritage speakers’ reanalyzed first language are often grammatically divergent from native speakers. Irrespective of the heritage language, there is converging evidence that the cognitive process of reanalysis of heritage languages is often evident in less salient properties of the language, such as inflectional morphology (Polinsky & Kagan, 2007). Therefore, Haitian Creole (HC) is a candidate for restructuring. In this investigation we compared the morphophonological patterns of the definite article system at the production and perception level between two groups of early learners of Haitian Creole (i.e. native speakers vs. United States (US) born heritage speakers).

The …

Affordable And Accessible Hearing Healthcare Interventions In The United States: A Literature Review And Prospective Analysis, Garrett Thompson

Dissertations, Theses, and Capstone Projects

Age-related hearing loss is a significant public health concern with serious and far-reaching consequences including: social isolation, depression, faster cognitive decline, and increased risk of falls. Hearing loss is a widespread condition, it is in fact a leading cause of disability among older people. Hearing aids, the primary intervention for adults with hearing loss, are costly and inaccessible to many patients who need them. Among other reasons, these factors have led to a low uptake rate among the adult population; only one in seven adults who could benefit from wearing hearing aids utilizes them. Given the status quo of high …

The question of interest in this study was whether bilingual individuals show superior executive control compared to monolingual participants. Findings are mixed, with studies showing advantage, disadvantage, or no difference between bilingual and monolingual speakers. In this study, we used different experimental conditions to examine implicit learning, resistance to interference, monitoring, and switching, independently. In addition, we matched our monolingual and bilingual participants on baseline response time. Bilingual participants demonstrated faster implicit learning, greater resistance to interference, more efficient switching compared to monolingual participants. The groups did not differ in monitoring. In conclusion, depending on task complexity and on the …

Phonetic Complexity Affects Children’S Mandarin Tone Production Accuracy In Disyllabic Words: A Perceptual Study, Puisan Wong, Winifred Strange

Publications and Research

This is the first study to examine the effect of phonetic contexts on children’s lexical tone production. Mandarin tones in disyllabic words produced by forty-four 2- to 6-year-old children and twelve mothers were low-pass filtered to eliminate lexical information. Native Mandarin speaking adults categorized the tones based on the pitch information in the filtered stimuli. All mothers’ tones were categorized with ceiling accuracy. Counter to the findings in most previous studies on children’s tone acquisition and the prevailing assumption in models of speech development that children acquire suprasegmental features much earlier than segmental features, this study found that children as …

Relative Clause Sentence Comprehension By Japanese-Speaking Children With Specific Language Impairment And Children With Typical Language Development, Miho Sasaki

Dissertations, Theses, and Capstone Projects

Comprehension of sentences with relative clauses was examined in Japanese-speaking children with SLI and children with TLD. The children with SLI showed comparable comprehension with the TLD peers, when the language and memory tests’ scores were controlled. The children with TLD consistently had difficulties in OR sentences than SR sentences, in spite of that Japanese relative clauses are different from English ones. The children with SLI showed the opposite pattern. Working memory rather than language knowledge predicted better the comprehension performance for all the children.

Perception And Production Of /V/ And /W/ In Hindi Speakers, Vikas Grover

Dissertations, Theses, and Capstone Projects

This dissertation examines the ability of Hindi speakers to identify, discriminate and produce two English phonemes /v/ and /w/ which are difficult for Hindi speakers to distinguish. In Hindi, /v/ and /w/ are used interchangeably. This pattern of use has transferred to Indian English, resulting in English /v/ and /w/ words showing variable pronunciations (e.g., “whale” or “vale” for the word “whale”). Hindi speakers were asked to identify, discriminate and produce tokens of /v/ and /w/. This study also examined whether experience with American English, related to the length of residence (LOR) in the US affects Hindi listeners’ perception and …
