Informationist Role: Clinical Data Management In Auditory Research, Karen L. Hanson, Theodora A. Bakker, Mario A. Svirsky, Arlene C. Neuman, Neil Rambo

Journal of eScience Librarianship

Informationists at NYU Health Sciences Libraries (NYUHSL) successfully applied for a NLM supplement to a translational research grant obtained by PIs in the NYU School of Medicine Department of Otolaryngology titled, “Clinical Management of Cochlear Implant Patients with Contralateral Hearing Aids”. The grant involves development of evidence-based guidelines for post-implant management of patients with bimodal cochlear implants. The PIs are also seeking to acquire new data sets to merge with grant-generated data. In light of the shifting data requirements, and the potential introduction of additional datasets, informationists will evaluate and restructure the data model and data entry tool.

Self-Ratings Of Communication Style And Discourse Performance Of Healthy Aging Adults, Hayley E. Besten

Theses and Dissertations--Communication Sciences and Disorders

This study investigated the accuracy of healthy aging adults‟ self-rating of communication style, as measured by quantifiable measures of discourse performance. Ninety cognitively healthy adults participated and comprised three age cohorts (20s, 40s, 60s). Participants completed discourse tasks that included recounting a vacation, telling a story, and describing a picture. Participants also self-rated their communication style, placing them in a talkative or reserved cohort. Communication style was measured by discourse performance variables of interest: length of output (TNW) and informativeness (%IU). When presented with an unconstrained task (recounting a vacation), talkative and reserved groups, regardless of age, produced a similar ...

Effects Of Coordinated Bilaterial Hearing Aids And Auditory Training On Sound Localization, Iman Elsabah Ibrahim

University of Western Ontario - Electronic Thesis and Dissertation Repository

This thesis has two main objectives: 1) evaluating the benefits of the bilateral coordination of the hearing aid Digital Signal Processing (DSP) features by measuring and comparing the auditory performance with and without the activation of this coordination, and 2) evaluating the benefits of acclimatization and auditory training on such auditory performance and, determining whether receiving training in one aspect of auditory performance (sound localization) would generalize to an improvement in another aspect of auditory performance (speech intelligibility in noise), and to what extent. Two studies were performed. The first study evaluated the speech intelligibility in noise and horizontal sound ...

Whole-Word Recognition From Articulatory Movements For Silent Speech Interfaces, Jun Wang, Ashok Samal, Jordan R. Green, Frank Rudzicz

Special Education and Communication Disorders Faculty Publications

Articulation-based silent speech interfaces convert silently produced speech movements into audible words. These systems are still in their experimental stages, but have significant potential for facilitating oral communication in persons with laryngectomy or speech impairments. In this paper, we report the result of a novel, real-time algorithm that recognizes whole-words based on articulatory movements. This approach differs from prior work that has focused primarily on phoneme-level recognition based on articulatory features. On average, our algorithm missed 1.93 words in a sequence of twenty-five words with an average latency of 0.79 seconds for each word prediction using a data ...

Familiality Of Auditory Evoked Potentials: Preliminary Investigation Of The Auditory Brainstem Response And Late Latency Cortical Response, Matthew B. Lucas

Electronic Thesis and Dissertation Repository

Twenty-four participants, consisting of six sibling pairs and six non-sibling pairs, participated in this study investigating the familiality of auditory evoked potentials (AEPs). The auditory brainstem response (ABR) recorded at high stimulus rates, revealed that Wave V latency increases, while amplitude decreases as stimulus rate increases. ABR Wave V latency was also found to increase with click position within a stimulus train, plateauing by the third stimulus. No evidence for familiality was found with respect to the ABR Wave V under these conditions. The late latency response (LLR) components N1 and P2 were found to decrease between the first and ...

The Effect Of Concurrent Cognitive, Linguistic And Motor Tasks On Speech Intensity In Parkinson’S Disease, Teresa J. Valenzano

Electronic Thesis and Dissertation Repository

This study investigated the effect of concurrent tasks on speech intensity in Parkinson’s disease (PD). Thirteen PD participants and twenty-two controls performed three tasks concurrent with a speech task. The speech task involved a repeated carrier phrase and a target word. The concurrent tasks involved math addition (cognitive), verb generation (linguistic), and manual visuomotor tracking (motor) at three levels of difficulty. All three concurrent tasks were associated with reduced speech intensity relative to the isolated speech task. The concurrent motor task was generally associated with the greatest reduction in speech intensity. Task performance measures were not significantly different for ...

The Effect Of Multitalker Background Noise On Speech Intelligibility In Parkinson's Disease And Controls, Talia M. Leszcz

Electronic Thesis and Dissertation Repository

This study investigated the effect of multi-talker background noise on speech intelligibility in participants with hypophonia due to Parkinson’s disease (PD). Ten individuals with PD and 10 geriatric controls were tested on four speech intelligibility tasks at the single word, sentence, and conversation level in various conditions of background noise. Listeners assessed speech intelligibility using word identification or orthographic transcription procedures. Results revealed non-significant differences between groups when intelligibility was assessed in no background noise. PD speech intelligibility decreased significantly relative to controls in the presence of background noise. A phonetic error analysis revealed a distinct error profile for ...

Loudness Perception And Speech Intensity Control In Parkinson's Disease, Jenna Paula Clark

Electronic Thesis and Dissertation Repository

This study investigated the role of loudness perception and selected auditory processes in 17 participants with hypophonia related to Parkinson’s disease (PD) and 25 controls. For most of the five loudness perception tasks (magnitude estimation, imitation, speech-to-noise judgment, magnitude production, magnitude production in noise), the PD participants produced a significantly different pattern and used a more restricted range than the controls in their self-generated estimates of speech intensity and judgments of speech loudness. Results from two self-assessment questionnaires (CETI-M, M-SAPP) found that the PD participants perceived themselves as less effective communicators than controls. An audiometric evaluation suggested that the ...

Factors In The Client-Clinician Interaction That Are Perceived To Influence Hearing Aid Adoption In First Time Hearing Aid Candidates And Their Rated Importance By Clients And Clinicians, Laya Poost-Foroosh

Electronic Thesis and Dissertation Repository

The purpose of this dissertation was to gain a better understanding of the impact of the client-clinician interaction in the hearing aid adoption process. The specific goals of this dissertation were: 1) to identify factors in client-clinician interactions that were perceived by clients and clinicians to influence hearing aid adoption in first time adult hearing aid candidates, 2) to investigate the importance of the identified factors from clients and clinicians perspectives, and 3) to compare the importance of the identified factors between clients and clinicians. These goals were achieved using a mixed-methods approach.

Three studies were undertaken. In the first ...
