Lack Of Protocol Standardization For Vestibular Evoked Myogenic Potentials, Kendall J. Werhane
MSU Graduate Theses
Vestibular Evoked Myogenic Potentials (VEMPs) are used in the field of Audiology to allow us to evaluate otolith and vestibular nerve function, which provides us with information that prior testing could not exclusively identify. While the collection of data from VEMPs is useful for many audiologic and vestibular diagnoses, achieving accurate recordings can be challenging due to the complex nature of testing. The article below will take a deep dive into different VEMP devices and the protocol they used to record VEMPs on their participants. The purpose of developing state-of-the-art (SOTA) equipment for VEMP testing is to ensure that the …

The Effect Of Different Warm-Up Durations On Subjective And Objective Measures Of Singing In Choral Singers Over The Age Of 55, Jeremy A. Chesman
MSU Graduate Theses
Choral singing is a popular activity in the United States. Choral singers are often encouraged to warm up vocally before they sing. Considering voice conditions, like presbyphonia, that can develop shortly after retirement, more research about vocal warm-ups is needed for those over the age of 55. This study assesses the effects of various durations of vocal warm-ups on subjective and objective measures of the singing voice using a within-groups design with randomized condition order. Nine participants performed vocal warm-ups for 0, 5, 10, and 15 minutes. A song sample was then recorded and sent to two expert raters who …
Investigation To Examine The Profile Of Auditory Brainstem And Hearing Thresholds Using Tone Burst Audiometry Brainstem Response In A Preclinical Migraine Model, Megan Huelsing
MSU Graduate Theses
Migraine is a disabling neurological disease that is characterized by prominent auditory symptoms, including hyperacusis, which is defined as extreme sensitivity to sounds. The goal of this study was to investigate changes in hearing sensitivity and neural changes in the brainstem by measuring neural activity of the auditory brainstem in an established preclinical model of chronic migraine. To induce a chronic migraine state within the trigeminal system, male and female Sprague Dawley rats were subjected to three known human risk factors including neck muscle tension and REM sleep deprivation that promote latent sensitization, and exposure to a pungent odor, which …
Modulation Of Electrocochleography Responses By Contralateral Broadband Noise In Young Adults, Riley J. Rickman
Modulation Of Electrocochleography Responses By Contralateral Broadband Noise In Young Adults, Riley J. Rickman
MSU Graduate Theses
While it is known the auditory efferent system contains two distinct subgroups – the medial olivocochlear nucleus (MOC) and the lateral olivocochlear nucleus (LOC) – not much is known regarding the function of the LOC in humans. This study aims to evaluate the effect of activating the lateral olivocochlear (LOC) neurons via contralateral broad band noise (CBBN) on electrocochleography responses. A ten-minute time-blocked paradigm was utilized to evaluate both the slow and fast effect of the LOC neurons. Recordings were obtained at four points within this ten-minute block both with and without the presence of 50 dB SPL CBBN to …
Speaker Encoding For Zero-Shot Speech Synthesis, Tristin W. Cory
Speaker Encoding For Zero-Shot Speech Synthesis, Tristin W. Cory
MSU Graduate Theses
Spoken communication, for many, is an essential part of everyday life. Some individuals can lose or not be born with the ability to speak. To function on a day-to-day basis, these individuals find other ways of communication. Adaptive speech synthesis is one of those ways. It recreates a user’s previous voice or creates a voice that blends with their regional dialect. Current adaptive speech synthesis techniques that achieve human-like speech require thirty minutes, to a few hours of high-quality audio recordings of a target speaker. This amount of recorded audio is not commonly possessed by people in need of a …
Effect Of Electrocochleography Stimulus Rate And Intensity On Identification Of Noise Induced Hidden Hearing Loss In Humans, Amanda E. Mccarthy
Effect Of Electrocochleography Stimulus Rate And Intensity On Identification Of Noise Induced Hidden Hearing Loss In Humans, Amanda E. Mccarthy
MSU Graduate Theses
Noise exposure has been known to cause both temporary and permanent shifts in hearing thresholds in humans. Animal and human studies have shown noise exposure to lead to damage to the ribbon synapses of the cochlea. This damage, referred to as noise induced hidden hearing loss (NIHHL), is not detectable with standard hearing assessments, though can be the cause of difficulties understanding speech in the presence of background noise. Recent studies have begun to explore the use of electrocochleography (ECochG) to detect this neural damage in humans. Such studies strive to aid in the development of a clinical tool for …
Frequency-Modulated Multiple-Tone Distortion Product Otoacoustic Emissions In Young Children With Normal Hearing, Kathryn Arielle Vlietstra Baker
Frequency-Modulated Multiple-Tone Distortion Product Otoacoustic Emissions In Young Children With Normal Hearing, Kathryn Arielle Vlietstra Baker
MSU Graduate Theses
Distortion-product otoacoustic emissions (DPOAEs) are objective tests of the integrity of the outer hair cells of the cochlea in response to a single-tone pair stimulus. Despite advances in DPOAEs test protocols and technology, there is little research about the use of frequency modulated tones to improve response characteristics. This study evaluates the efficacy of a new frequency modulated stimulus with multiple-tone pair DPOAEs (mDPOAEs) compared to the standard stimulus protocol for mDPOAEs to determine whether frequency modulation (FM) will achieve more robust and faster results. Normative data for this novel test protocol were obtained in 11 healthy normal-hearing children aged …
Content Validity Of Aba Language Assessments In The Totality Of Skinner's Verbal Operant Theory, Taylor Marie Lauer
Content Validity Of Aba Language Assessments In The Totality Of Skinner's Verbal Operant Theory, Taylor Marie Lauer
MSU Graduate Theses
Content validity describes the degree of which a measure represents all the components of the overall construct being measured. Behavior analytic language assessments are largely based on Skinner’s verbal operant theory (1957). Three behavior analytic language assessments were utilized to measure the coverage of Skinner’s verbal behavior theory: the VB-MAPP, ABLLS-R, and PEAK. The purpose of the current study was to examine the content validity of each of these assessments coverage on the totality of Skinner’s verbal operant theory. Expressive items on each of the three assessments were compared to definitions of Skinner’s verbal operants and were coded as the …
The Effect Of Rate On Tone Burst Extratympanic Electrocochleography In Adults With Normal Hearing, Alana E. Kennedy
The Effect Of Rate On Tone Burst Extratympanic Electrocochleography In Adults With Normal Hearing, Alana E. Kennedy
MSU Graduate Theses
The recording of electrocochleography (ECochG) to tone burst stimuli with a high rate is hypothesized to provide advantages over standard click ECochG with slow rate. Specifically, the use of tone burst stimuli presented at a high rate may enhance the summating potential (SP) while also reducing neural contributions in the response. To allow for the analysis of the complex ECochG responses to high rates, the Continuous Loop Averaging Deconvolution (CLAD) technique was employed to deconvolve the responses. This study examined the effect of high rate and stimulus duration on the SP amplitude of tone burst extratympanic ECochG in 20 adult …

A Multi-Generational Deaf Family: A Case Study On Literacy, Rubecca Sue Wilson
MSU Graduate Theses
Literacy is a crucial component of life in our society, and the journey to becoming fluent readers begins before conventional classroom instruction. Literacy rates of adults who are deaf and hard of hearing are consistently in the fourth grade, age nine to ten years, range. In order to help build more skilled readers who are deaf and hard of hearing, it is critical to increase understanding of how deafness affects the development of literacy. This case study was of a family of six with all members' deaf and American Sign Language (ASL) as their first language. The purpose of this …
The Effect Of Wideband And Narrowband Noise On The Olivocochlear Bundle And The Cochlear Microphonic, Catherine Nicole Palmietto
The Effect Of Wideband And Narrowband Noise On The Olivocochlear Bundle And The Cochlear Microphonic, Catherine Nicole Palmietto
MSU Graduate Theses
In humans, activation of the olivocochlear bundle (OCB) can have a suppression or enhancement effect on cochlear processes. This phenomenon was studied via OCB activation effects on otoacoustic emissions (OAEs). However, it has been suggested that cochlear microphonics (CMs) can provide better, more detailed information regarding OCB function. In the present study, 22 normal hearing female subjects between the ages of 18-30 were recruited and the OCB was examined via the recording of CMs under changes in three conditions: OCB activating noise, stimulus polarity and stimulus frequency. Specifically, the present study examines the effects of activating wideband noise and narrowband …
Effects Of Sleep Deprivation With 110-Minute Rest Period On Postural Control In Young Adults, Whitney L. Hayden
Effects Of Sleep Deprivation With 110-Minute Rest Period On Postural Control In Young Adults, Whitney L. Hayden
MSU Graduate Theses
Computerized Dynamic Posturography (CDP) is used by many different professionals as an objective tool to measure different aspects of postural control. For audiologists, CDP is used to assess the vestibular system and its interactions with the somatosensory and visual systems. There is evidence that postural control is negatively affected by sleep deprivation. To date, there is limited knowledge on whether a 110-minute rest period will improve or even restore postural control abilities back to baseline. The present study was designed to further study the effects of sleep deprivation on different aspects of postural control and to examine the effectiveness of …

Two surveys were sent to teachers and teacher candidate graduate students from a Midwestern university. Participants were asked to answer one of the two surveys depending on whether they had their teaching certificate or were working to receive their teaching certificate. The participants answered survey questions about their college experience with rubrics and their experience and opinions of rubrics in their own, or future, classrooms. The research demonstrated that: …
Sleep Deprivation And Recovery: The Effects Of P300 Three And Six Hours Post Recovery, Kimberly A. Brauer
Sleep Deprivation And Recovery: The Effects Of P300 Three And Six Hours Post Recovery, Kimberly A. Brauer
MSU Graduate Theses
The P300 waveform is an auditory evoked potential (AEP) elicited through a decision making process. Due to the endogenous nature of the P300 response, which requires participants to actively respond to an auditory stimuli, it has been used as on objective measure to evaluate the cognitive processes of attention and memory. Previous studies have looked at the P300 before and after sleep deprivation as well as after brief rest periods. Evidence shows that a decline in P300 amplitudes and increase in latency are seen after 24 hours of sleep deprivation and improvements in the P300 are seen after a recovery …
Spatial Irregularities Of Compound Action Potential Origination In Individual Cochleae, Kaitlyn M. Kennedy
Spatial Irregularities Of Compound Action Potential Origination In Individual Cochleae, Kaitlyn M. Kennedy
MSU Graduate Theses
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 …
