Release From Masking: Behavioral And Physiological Masking Level Differences, Sarah L. Hodgson

Dissertations, 2014-2019

Binaural hearing offers several advantages over monaural hearing and is believed to be one factor that is involved in the ability to understand speech in background noise. Binaural hearing involves analysis of interaural timing and intensity differences in signals arriving at the two ears which provides listeners with sound localization cues as well as signal in noise detection. When sounds arrive at each ear at slightly different times, there may be a release from the effects of background noise, allowing listeners to detect softer sounds in noise. Masking Level Differences (MLDs) have been widely used to evaluate behavioral binaural processing. …

Wideband Acoustic Immittance And Dpoae Changes In Older Adults, Mandy M. Williams

Dissertations, 2014-2019

This study examined the effect of middle ear aging in adults using wideband acoustic immittance (WAI) measures. WAI and traditional 226 Hz tympanometry were measured in 25 young adult ears (ages 18-25) and 26 older adult ears (ages 50-71) with normal middle ear status. While minimal differences between older and younger adults were observed with 226 Hz tympanometry, significant age effects were seen with WAI measures. The older adults demonstrated a statistically significant increase in middle ear absorbance at lower frequencies (226-1,260 Hz) and decreased absorbance at higher frequencies (4,000-5,040 Hz) compared to the younger adult group. While the effect …

The Effect Of Auditory Fatigue On Reaction Time In Normal Hearing Listeners At Different Signal To Noise Ratios, Haley Athey

Dissertations, 2014-2019

This study examined the effect of listening fatigue on the reaction time of young, normal hearing listeners at +5 and +10 dB signal to noise ratio. Reaction time was measured in a single task paradigm on twenty listeners (ages 19-30 years) before and after a fatigue-inducing listening task. The participants also completed a subjective rating questionnaire at the two intervals. Results indicated that there was no significant difference between the reaction times before and after listening fatigue. However, for a subgroup of stimuli (nonsense syllables ending with consonants) the reaction time was 52 msec longer after listening fatigue. The participants …

The purpose of the current study is to examine the effects of EAA on social skills and expressive language in 2-4 children diagnosed with developmental disability. Participants engaged in …

Creating Therapy Materials To Improve Communication Of Young Children, Allison J. Corey

Senior Honors Projects

Once children start preschool, they should be able to speak in simple sentences and use basic syntax. When they complete preschool and begin kindergarten, they should be using complete, complex sentences, have an extensive vocabulary, and use correct grammar. However, sometimes a child’s language doesn’t develop as expected resulting in speech delays or impairments. This problem could arise for a multitude of reasons, for example, the child may be on the autism spectrum, he/she may have a specific language delay, or it may be due to an articulation/phonology problem. The role of a speech language pathologist (SLP) in a school …

Spatial Irregularities Of Compound Action Potential Origination In Individual Cochleae, Kaitlyn M. Kennedy

Graduate Theses/Dissertations

The present study aims to evaluate the origin of compound action potential (CAP) responses in the guinea pig ear using the following method. Pipettes were sealed into the cochlear apex of 26 guinea pigs to inject ototoxic pharmaceuticals that inhibit nerve responses without affecting cochlear function. The rate of the injection was adjusted once each minute to account for variations in the diameter of the cochlea and to maintain a steady flow of pharmaceuticals. CAP measurements collected at around 90-second intervals using tone burst stimuli during the injections allowed evaluation of the neural responses over time. Responses to higher stimulation …

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 …

The Effect Of Grief On Bonding With A Deaf Child, Gabriela Cardona

Senior Honors Projects

Since hearing screenings for children happen after birth, there is no way for

parents to prepare themselves for having a child with hearing loss and any

lifestyle changes that will follow. Many parents have trouble coping with and

accepting the news of having a deaf or hard-of-hearing child. This diagnosis also

often brings along with it the stress of additional necessary appointments and

decisions. The parent’s idea of a “perfect and ideal” child is gone. Parents need

to grieve the loss of this idea while also tending to their child and giving their

child the opportunities and support needed for …

Effects Of Talker Variability On Spectral Contrast Effects., Asim Mohiuddin

College of Arts & Sciences Senior Theses

Spectral contrast effects are context-dependent effects that influence the way we perceive certain sounds. Evidence of these effects can be seen in experiments where a precursor sound (e.g. a sentence) is followed by a target vowel sound (like /ɪ/ as in "bit" or /ɛ/ as in "bet"). If the precursor's frequency was emphasized in areas more consistent with the frequency of /ɛ/, listeners tend to perceive the target sound to be the opposite i.e. /ɪ/. A recent study shows using sentence precursors from 200 different talkers diminishes these effects questioning previous claims that talker variability has no influence on spectral …

The Effect Of Easy Onset Time Treatment On Voice Onset Time In Stuttering, Candace M. Franklin

Honors Theses

For over 70 million people who stutter, it is a disorder that can affect a person’s social, emotional, and professional life on a daily basis (Gordon, 2002). Stuttering is defined as a fluency disorder that includes the repetition of words, pauses in speech, or sound prolongation (Hedge, 2001). Although there are many different theories as to what causes stuttering, the etiology of stuttering remains undetermined. As a result, much research has been done on various treatment approaches to try and ease the effects of stuttering. One particular approach is the Easy Onset Time approach. This approach encourages the client to …

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 …

Variability In Clinically Measured Wideband Acoustic Immittance Over Time In Young And Old Adults, Allison G. Mcgrath

Dissertations, 2014-2019

Wideband acoustic immittance (WAI) measures of the middle ear have the potential to increase our ability to detect changes in the middle ear transfer function not seen using traditional tympanometry. In order to use this new tool diagnostically we must first understand its normal clinical variability. The present study aimed to investigate the variability that occurs when wideband acoustic immittance (WAI) is measured clinically within subjects as a function of subject age, as a function of time, and as a function of pressure. A total of thirty-six ears from eighteen subjects were studied (n=18 young adults ears, n=18 older adult …
