Recognition And Comprehension Of Speech In Noise In School-Aged Children With Unilateral Hearing Loss, Amanda M. Griffin Aug 2015

Recognition And Comprehension Of Speech In Noise In School-Aged Children With Unilateral Hearing Loss, Amanda M. Griffin

Doctoral Dissertations

Sentence recognition and auditory comprehension abilities of young adults with normal hearing (NH) and school-age children with NH and unilateral hearing loss (UHL) were tested in a mixed design. In Experiment 1, subjects’ sentence recognition abilities were measured in the presence of speech spectrum noise (SSN) and two-talker child babble (TTB) in co-located and spatially-separated target and masker configurations. In all conditions, reception thresholds for sentences (RTS) improved with age from six-to 12 years. Speech spectrum noise proved to be a more effective masker than TTB in all listening conditions, suggesting subjects were able to take advantage of temporal and …


Effectiveness Of Proloquo2goTm In Enhancing Communication In Children With Autism During Aba Therapy, Taylor Eastin Krcek May 2015

Effectiveness Of Proloquo2goTm In Enhancing Communication In Children With Autism During Aba Therapy, Taylor Eastin Krcek

Doctoral Dissertations

Autism is a bio-neurological developmental disorder presenting in early childhood that has a profound effect on an individual's ability to communicate. The iPad® with the Proloquo2GoTM app is a multilingual Augmentative and Alternative Communication (AAC) solution designed to assist people who have difficulty speaking or cannot speak at all. This study examines the effectiveness of the Proloquo2GoTM app delivered via iPad® to enhance the tacting, manding, and verbal completion repertoires of children with autism. Participants included five children between the ages of three and four years old diagnosed with an autism spectrum disorder (ASD) and with low to …


The Effect Of Auditory Processing Abilities On Acceptable Noise Levels, Brandee E. Richardson Apr 2015

The Effect Of Auditory Processing Abilities On Acceptable Noise Levels, Brandee E. Richardson

Doctoral Dissertations

The purpose of the present study was to determine typical acceptable noise levels (ANLs) in children diagnosed with auditory processing disorder (APD) and compare those to ANLs in children without APD. Sixteen participants, eight children with APD and eight children without APD, were administered a complete audiological evaluation and a series of APD tests [Filtered Words, Competing Sentences, and Auditory Figure Ground (0) subtests of the SCAN– 3C; Staggered Spondaic Word test; and Pitch Pattern test] to determine normal or abnormal auditory processing ability. Conventional ANLs were measured on each participant to determine acceptance of background noise. The results …


Ear Specific Anl Measurements In Individuals With Unilateral And Asymmetrical Sensorineural Hearing Loss, Rebecca Howard Apr 2015

Ear Specific Anl Measurements In Individuals With Unilateral And Asymmetrical Sensorineural Hearing Loss, Rebecca Howard

Doctoral Dissertations

The present study sought to determine if ANLs differ between ears within subjects with unilateral or asymmetrical SNHL. ANL was measured in four conditions (i.e., binaural, better ear, poorer ear unmasked, and poorer ear masked) in fifteen adults, nine with unilateral SNHL and six with bilateral asymmetrical SNHL. A significant difference between ANL in the four conditions (i.e., binaural, better ear, poorer ear unmasked, and poorer ear masked) was identified; however, the subjects with unilateral and asymmetrical SNHL behaved similarly throughout the testing. When comparing the four conditions, the results showed a significant difference between both the binaural ANL and …


Grant Proposal: Effects Of Sound Field Amplification On Standardized Test Scores, Jessica Ivey Coker Apr 2015

Grant Proposal: Effects Of Sound Field Amplification On Standardized Test Scores, Jessica Ivey Coker

Doctoral Dissertations

Research has shown that the majority of classroom environments lack appropriate acoustical standards to ensure optimal learning conditions. During the early school grades, it is especially crucial that students overcome poor listening environments to obtain the fundamental educational skills necessary for academic success. Furthermore, the State of Louisiana conducts standardized test assessments (LEAP and iLEAP) to measure the students' knowledge and skills gained. These standardized test scores not only determine if the student progresses to the next grade, but also influences the amount of federal revenue and how the revenue is allocated to the schools. A proposed remedy to …
