Examining The Effect Of Training Using Natural And Noise-Vocoded Sentences On Noise-Vocoded Speech Perception In Normal-Hearing Listeners, Alexis Leiderman

Dissertations, Theses, and Capstone Projects

Auditory training has been shown to be an intervention strategy that may improve speech perception abilities in individuals with and without hearing loss. Within the cohort of individuals with hearing loss, auditory training has also been shown to have an improvement on speech perception in cochlear implant users. In several training studies, normal-hearing listeners have been exposed to noise-vocoded speech using auditory training paradigms to mimic how cochlear implant users may in turn be affected by these paradigms. These studies have highlighted certain areas for improvement in speech perception abilities based off of the training paradigms put in place. Several …

Examining The Effect Of Talker Familiarity Using Familiar And Unfamiliar Talkers On Noise-Vocoded Speech Perception In Normal-Hearing Listeners: A Training Study, Daria N. Collins

Dissertations, Theses, and Capstone Projects

Auditory training studies utilizing stimuli that are applicable to real-world processing of speech have been shown to improve speech perception abilities in normal hearing populations, those with hearing loss, and cochlear implant wearers. In particular, exposing normal hearing adults to noise-vocoded speech via auditory training studies has been shown to not only simulate the perceptual experience of a cochlear implant wearer, but have demonstrated promising improvements on speech perceptual abilities via the training paradigm. Additionally, studies have highlighted various variables that impact speech perception, including, talker familiarity. Talker familiarity has been shown to enhance speech perception both in listeners with …

Training To Avoid Distractions, Cara E. Sanderson

Dissertations, 2014-2019

Introduction: Auditory training has been extensively studied and applied to training software that is currently available for children with attention, hearing, or speech/language difficulties. The extent to which training generalizes, or transfers to an untrained task, is of great theoretical value. To our knowledge, there has not been a study that examines transference to a non-sensory masking task.

Methods: 16 adults without ADHD were trained in a contralateral masking task over the course of two days, with 900 trials per day. False alarm rates, thresholds, and reaction times were measured. Pre- and post-tests of contralateral and informational masking were conducted …

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

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 …

Dichotic Auditory Training In 6 To 15 Year Olds, Chasity M. Mccrum

Doctoral Dissertations

The purpose of this study was to determine if participants with normal auditory processing skills would improve after receiving the Dichotic Auditory Training (DAT) when compared to a group of normal participants who only received pre- and post-testing. Twenty participants, age 6:0 to 15:11 years, participated in this study. A standard audiological evaluation was completed for each participant. Pretest and posttest were completed that included (1) DAT testing, (2) SCAN-C/A, (3) Staggered Spondaic Word test, and (4) Dichotic Digits (Single/Double). The results were analyzed for statistically significant differences between pre- and post-testing results and between groups. Any significant results …

Effects Of Dichotic Auditory Training On Children With Central Auditory Processing Disorder, Kiley Edwards Stephenson

Doctoral Dissertations

(Central) auditory processing disorder (CAPD) is a condition in which individuals with normal hearing present with difficulties often associated with hearing loss. While there are currently many tests available for the CAPD assessment, there are very few therapies for the remediation of a CAPD. A new therapy program, called Dichotic Auditory Training (DAT), aimed at improving the performance of those individuals with CAPD, was the focus of this study. Eight children between the ages of seven and twelve went through the four week training. The Staggered Spondaic Word (SSW) test, the SCAN-C/A, and a test designed after the DAT …
