Audiological Evaluation Of Persons With Dementia: A Systematic Review, Yehudis Hoch

Dissertations, Theses, and Capstone Projects

Background: Dementia and hearing loss are both prevalent, age-related conditions and recent research has established a correlation between the two. Audiological evaluations of persons with dementia are important due to a likely comorbidity of dementia and hearing loss, the detrimental effect that hearing loss has on cognition and cognitive tests, and because the similar presentation of the two conditions can cause hearing loss to be overlooked. Hearing loss intervention is critical for this population due to the positive effects that amplification has on cognition, social engagement, and listening effort. Despite the importance of hearing assessment and intervention, audiological evaluation of …

Investigating Self-Perception Of Speech And Motivation For Return To Intervention For Post Cochlear Implantation In Young Adults, Madison Henry

Electronic Theses and Dissertations

Introduction: Cochlear Implants (CI) are designed to address severe to profound hearing loss. When implantation occurs after language develops, it is referred to as post-lingual (PL) implantation. Currently, no interventions have been identified to address the communication challenges that young adults with PL-CIs may face after they complete post-CI rehabilitation services. This study analyzes if an individualized intervention plan is beneficial for a person with PL-CIs when experiencing changing communication demands in the transition to college or the workforce. Methodology: Baseline assessments were conducted; the results of which allowed for the establishment of four co-constructed goals. These goals were targeted …

Validation Of A Virtual Auditory Space, And Its Use To Investigate How Pitch And Spatial Cues Contribute To Perceptual Segregation Of Auditory Streams, Nima Zargarnezhad

Electronic Thesis and Dissertation Repository

The human auditory system can decompose complex sound mixtures into distinct perceptual auditory objects through a process (or processes) known as Auditory Scene Analysis. Pitch and spatial cues are among the sound attributes known to influence sequential streaming (Plack 2018). In this project, the fidelity of a virtual acoustic space (the Audio Dome) in reproducing precisely located sound sources with a 9^th-order ambisonics algorithm was validated. The estimated horizontal Minimum Audible Angles aligned with previously reported values (Mills 1958) homogeneously across the space, and a robust low-frequency presentation was identified. Then, the Audio Dome was utilized to test …

The Role Of Vocal Development Patterns: Predicting Neurogenetic Risk In Infancy Using Early Vocal Development And Sex, Alyssa Cregg, Rachel Siela, Olivia Battaglia, Kaylee Bobay, Madison Chin, Athena Fordwor, Conghao Gao, Deeksha Handa, Erin Lee, Tiernan Mcdivitt, Grace Strabala, Victoria Tuell, Laurel Williams

The Journal of Purdue Undergraduate Research

Extant literature documents a higher rate of language/speech disorders in males; however, despite sex being a potential moderator of outcomes, we do not know what role it plays in early vocal behavior of infants at high risk for such disorders. The purpose of this study was to ask: (1) Do high-risk infants demonstrate atypical vocal development patterns? (2) Is the quality and quantity of early babble distinct for male and female infants, and does this pattern vary across risk? To answer these questions, we examined the canonical babbling ratio (CBR; the ratio of canonical syllables, those with a consonant and …

How Phonological And Syntactic Overlap Impact Cognate Processing Speeds In Bilinguals, Ella Marie Peterson

Undergraduate Theses, Professional Papers, and Capstone Artifacts

This paper investigates individuals who are proficient in two languages (bilinguals) and the speeds at which bilinguals process cognates (words with comparable form and meaning across languages). This paper cites two ongoing experiments: The Language Identification (LID) task and the Self-Paced Listening (SPL) task. Findings from the LID suggest that phonological overlap in cognates facilitates bilingual language processing speeds, when cognates are presented in isolation. Findings from the SPL suggest that syntactic overlap in cognates also facilitates bilingual language processing speeds, when cognates are presented in sentences. These findings are significant in that the tasks present cognates to participants in …

Methods: A literature search was performed in three databases: CINAHL, Cochrane Central, and PubMed. The PRISMA template was used to record the search and selection process. Search criteria included older adults aged 65 and up with diagnosed or self-reported hearing loss and no previous diagnosis of dementia or Alzheimer’s disease. Participants were excluded if they had been diagnosed with dementia or tested for it before the study began. Hearing loss was categorized using …

Numerical Investigation Of Subglottal Stenosis Effects On Human Voice Production, Dariush Bodaghi

Electronic Theses and Dissertations

This dissertation aimed to advance knowledge of how subglottal stenosis impacts voice production physiology. An in-house fluid-structure-acoustic interaction approach based on the hydrodynamic/acoustic splitting technique was employed. This technique was rigorously verified for simulating phonation by matching the acoustic behavior to a compressible flow solver for phonation-relevant geometries. Simulations of an idealized 2D vocal tract model demonstrated the effects of supraglottal acoustic resonance on vocal fold kinematics and glottal flow waveform. Results showed that the acoustic coupling between higher harmonics and formats generated pressure oscillations, modifying vocal fold dynamics and glottal flow rate.

A major novelty was the incorporation and …

Knowledge And Perceptions Of Slp Graduate Students Regarding Multiculturalism, Evy Jewell Hayes, Laura Amanda Mathews

Teaching and Learning in Communication Sciences & Disorders

Populations in the United States rise daily, as do the number of people who are considered multicultural. With this comes a greater need for speech-language pathologists (SLPs) who are able to assess and treat such individuals – a training process that begins in graduate programs. The primary objective of this study was to determine the knowledge and perceptions of graduate students in speech-language pathology as it pertains to multiculturalism. A survey was conducted to explore graduate students’ knowledge and perceptions of multicultural topics. Participants were recruited from programs in the southeastern United States via email. Just under 400 surveys were …

Trumpet Directivity From A Rotating Semicircular Array, Samuel D. Bellows, Joseph E. Avila, Timothy W. Leishman

Directivity

The directivity function of a played musical instrument describes the angular dependence of its acoustic radiation and diffraction about the instrument, musician, and musician’s chair. Directivity influences sound in rehearsal, performance, and recording environments and signals in audio systems. Because high-resolution, spherically comprehensive measurements of played musical instruments have been unavailable in the past, the authors have undertaken research to produce and share such data for studies of musical instruments, simulations of acoustical environments, optimizations of microphone placements, and other applications. The authors acquired the data from repeated chromatic scales produced by a trumpet played at mezzo-forte in an anechoic …

Recursive Functional Learning In Nonfluent Aphasia, Gerald C. Imaezue

Dissertations, Theses, and Capstone Projects

People with nonfluent aphasia (PWNA) require feedback from an external agent as well self-feedback to facilitate performance of language production tasks. The extent to which PWNA can use self-feedback alone to improve their task performance is unknown. In addition, it is argued that self-feedback may reinforce or minimize performance errors over time. To test whether either is the case, we introduce an original learning mechanism, recursive functional learning, which uses self-feedback loops to optimize recursively multiple subsystems (cognitive and linguistic subsystems) that PWNA engage during task performance. We used this mechanism to underpin a novel automated procedure we developed, recursive …

Loudness Matching In Individuals With Parkinson’S Disease And Hypophonia, Catherine Johnson

Electronic Thesis and Dissertation Repository

The purpose of the present study was to investigate speech loudness perception in 15 individuals with Parkinson’s disease (IWPD) and hypophonia (reduced speech intensity) and 15 healthy control (HC) participants. A loudness matching procedure was used to examine conditions involving speech loudness targets presented at various levels (60 to 80dB SPL). The loudness response conditions included manually controlled audio playback of external speech, self-vocalized speech, amplified self-speech, and speech projected to a distance of 2 meters. For most of the loudness matching conditions, the PD group did not demonstrate the predicted deficit in loudness matching. In some loudness matching conditions, …

The Directional Effect Of Target Position On Spatial Selective Auditory Attention, Heesung Park

Dissertations, 2020-current

Spatial selective auditory attention plays a crucial role in listening in a mixture of competing speech sounds. Previous neuroimaging studies have reported alpha band neural activity modulated by auditory attention, along with the alpha lateralization corresponding to attentional focus. A greater cortical representation of the attended speech envelope compared to the ignored speech envelope was also found, a phenomenon known as 'neural speech tracking’. However, little is known about the neural activities when attentional focus is directed on speech sounds from behind the listener, even though understanding speech from behind is a common and essential aspect of daily life. The …
