The Effect Of Frequency Resolution On Intelligibility Sentence And Its Relevance To Cochlear Implant Design, Seth H. Roy
The Effect Of Frequency Resolution On Intelligibility Sentence And Its Relevance To Cochlear Implant Design, Seth H. Roy
Department of Computer Science and Engineering: Dissertations, Theses, and Student Research
The purpose of this study is to understand how electrical stimulation (as opposed to acoustical stimulation) of the auditory nerve is used in cochlear implants. Speech is a complex signal that changes rapidly in time and frequency domains. Since phonemes (the smallest unit of speech that distinguishes words) depend on nuanced differences in frequency patterns, it would be expected that a signal with drastically reduced frequency information would be of limited value for conveying speech. Such a frequency-poor signal is the object to be investigated in the present work. It is also the basis of the way speech is represented …

A Case Study Of Cochlear Implants And Complications, Carly E. Amurao
Senior Honors Projects
A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear, allowing the individual access to sound. In recent years, there has been tremendous progress in developing technology in the area of cochlear implants to aid those with severe/profound hearing loss. Specifically, there has been a movement towards bilateral implantation. Each cochlear implant candidate has a unique hearing loss, and must reach required bench marks in order to be considered a viable candidate for a cochlear implant. This process includes: meeting the required level of hearing loss, a required trial with hearing aids that …
List Equivalency Of The Azbio Sentence Test, Lauren C. Bush
List Equivalency Of The Azbio Sentence Test, Lauren C. Bush
Honors Theses
The AzBio Sentence Test was developed as a measure of speech perception abilities and intended to be more reliable and closer to real life conditions than the previous speech perception measures commonly used. The purpose of speech perception measures is to partially determine cochlear implant candidacy as well as pre- and post-outcomes of cochlear implantation. The AzBio Sentence test is composed of 15 lists of 20 sentences each. There is limited research conducted on the equivalency of each of these lists. Of the previous limited reasearch conducted, one study found that only 10 of the 15 lists were equivalent. The …

The Psychological Effects Of Cochlear Implants: A Comparison Of One Adult With A Cochlear Implant And One Without., Sarah Schwartzer
Williams Honors College, Honors Research Projects
This study involved the development, implementation and analyzation of two qualitative case studies, with one involving a profoundly deaf individual who possesses a cochlear implant, the other with an individual who possesses normal hearing ranges. Participants were given two quantitative measures of observation, the Acceptance and Action Questionnaire and the Thought Control Questionnaire, before participating in a semi-structured interview that was intended to gather information about the individuals, their life experiences, and the factors of psychological flexibility, adaptability and resiliency as applied to their lives. The semi-structured interview involved a set list of questions that were posed to the individuals; …
Factors That Influence Device Selection By Parents Of Pediatric Cochlear Implant Candidates, Zachary W. Moore
Factors That Influence Device Selection By Parents Of Pediatric Cochlear Implant Candidates, Zachary W. Moore
Senior Independent Study Theses
The purpose of this study was to investigate factors/variables and the importance of those factors during cochlear implant (CI) device selection by parents of recent pediatric CI recipients in the United States. The researcher created an electronic survey and asked audiologists and hearing-related professionals at various hospitals and CI centers across the United States to distribute the survey link to the parents of any of their pediatric CI patients who received CI surgery within the past two years under the age of five years. The survey included both Likert-type and open-ended questions regarding the importance of various factors/variables to the …
