  1. Frequency Lowering in the Pediatric Population: Outcomes and Considerations for Fitting

    Ross, Lauren Virginia
    Children with hearing loss are at a disadvantage for language learning because they are unable to hear many of the important, yet subtle, cues necessary for speech and language development. Even when using current digital hearing aids, children with hearing loss are often unable to hear speech cues in the high frequency range. Frequency lowering is a processing strategy in which the hearing aid transfers higher frequency inputs to a lower frequency range that can be adequately amplified by the device. Two types of frequency lowering algorithms are currently available for use in children and have been shown to be...

  2. Ear-Specific Cochlear Implant Outcomes in Younger and Older Adults

    Krygowski, Molly
    Auditory information is transmitted from the ear to the brain along an intricate network of structures that comprise the central auditory nervous system. It is well documented that the neural pathway from the ear to the contralateral auditory cortex is stronger and more efficient than the pathway from the ear to the ipsilateral auditory cortex (Lazard et al., 2012; Lipschutz et al., 2002). In the majority of individuals, a functional specialization of the left cerebral hemisphere exists for language processing (Geschwind, 1972; Geschwind & Levitsky, 1968; Kimura, 1961; Jancke et al., 2002; Tervaniemi & Hugdahl, 2003). Due to this crossed...

  3. Evaluating the TEN Test in the Identification and Monitoring of Cochlear Dead Regions and Cochlear De-afferentation in Rats with Noise Induced Hearing Loss

    Kerns, Katherine Anne

  4. Privacy and Security in the Clinical Audiology Setting: Ohio Audiologists' Knowledge of the Health Insurance Portability and Accountability Act

    Antalovich, Anne Catherine
    The purpose of this study was to investigate the knowledge possessed by professionally licensed audiologists regarding the Health Insurance Portability and Accountability Act of 1996 (HIPAA) and its implications for clinical audiological practices. The study also aimed to examine the training and enforcement of HIPAA regulations in audiology clinics and facilities. A 30-question survey was distributed to professionally licensed audiologists in Ohio via an online survey instrument. The survey focused on audiologists’ knowledge of HIPAA regulations as well as corresponding sources of education and training. Subsequently, six pre-generated discussion questions were electronically distributed to Ohio audiologists. The discussion questions focused on the HIPAA training and education provided to audiologists...

  5. Oral Bilingualism in Children Who Are Deaf and Hard of Hearing

    Strang, Megan Lisbeth

  6. The Relationship Between Nonword Repetition, Vocabulary, and Reading in Children with Cochlear Implants

    Sansom, Emily
    The aim of the present study was to investigate how children with cochlear implants (CI) perform on a nonword repetition (NWR) task compared to their normally-hearing (NH) peers. One hundred and four second-grade children participated in this study: 49 with NH and 55 with severe-to-profound hearing loss who wore CIs. Along with NWR, children were tested on four other measures: phonological processing and working memory, which were evaluated as skills that potentially underlie NWR skills; and expressive vocabulary knowledge and word reading, which were evaluated as skills that are potentially based on NWR skills. The groups’ performance on these four...

  7. The Development of an Assessment Manual for 4th Grade Oral and Written Narratives

    Low, Keri E.
    Despite advances in hearing technology, children with hearing loss remain at risk for having oral and written language difficulties. Assessing a child’s narrative ability is one of the most informative methods of measuring language competence. In-depth analyses of narrative ability in children with hearing loss, particularly children who use cochlear implants, are lacking. Furthermore, there is a clear need for research examining the differences in oral and written narrative skills in children with hearing loss. The purpose of this project was to develop an assessment tool that evaluates oral and written narrative abilities in school age children. This document reviews...

  8. Hearing Loss and Co-Occurring Developmental Disability: Recommendations for Improved Clinical Practice

    Grumm, Mandi
    It is well-known that children with developmental disabilities are at greater risk for hearing loss. Although proper audiologic care is imperative for all children with hearing loss, those diagnosed with multiple disabilities often face unique challenges due to varying degrees of cognitive and physical impairment. For some children with critical health concerns, diagnosing and treating hearing loss may not always be a primary goal for families. Pediatric audiologists must be equipped to support these families by identifying, diagnosing, and providing intervention options for children with developmental disabilities. However, traditional audiologic protocols are not always appropriate for patients with unique needs....

  9. Increasing Adherence: Learning to Counsel Your Patients for Better Outcomes

    Cherry, Megan M.
    The biomedical conceptual model emphasizes the concept of disease or absence of disease for diagnosis whereas the biopsychosocial model emphasizes social and emotional factors for diagnosis. This concept of incorporating social and emotional factors has led to development and research into the importance of the patient-healthcare professional relationship. A patient who trusts his or her healthcare professional is more likely to divulge emotional issues. Additionally, it is important to train healthcare professionals to identify emotional issues and to work with the patient to increase quality of life. The patient’s concerns must be addressed for the patient to follow the clinician’s...

  10. The effects of high-pass masking on stimulus rate changes in the auditory brainstem response

    Hambley, Ellen R.
    The auditory brainstem response (ABR) to tonal stimuli is routinely used in a clinical setting to obtain estimates of hearing sensitivity. The latency and amplitude of ABR waveforms vary with stimulus frequency, intensity, and rate. However, interactions among these stimulus parameters on the ABR have only recently been fully examined. A study measuring effects of all three stimulus parameters in the same subjects demonstrated a latency shift of ABR Wave V in response to an increase in stimulus rate that was significantly greater for low frequency, low intensity stimuli than for other stimulus conditions tested (Hess and Hood, 2012). The...

  11. The Use of Mild Gain Hearing Aids for Adults with Auditory Processing Difficulties

    Moore, Donna
    The purpose of the present study was to investigate the effect of mild gain hearing aids with directional microphones and noise reduction in adults with auditory processing difficulties. Eleven adults with normal peripheral hearing but complaints and case history consistent with auditory processing difficulties completed speech in noise testing with and without the use of hearing aids and completed questionnaires addressing listening difficulties following testing with and without hearing aids. They also answered a question about their perception of anxiety during testing with and without hearing aids. The adults demonstrated significant improvements on speech in noise testing and on the...

  12. A Comprehensive Review of the Vestibular System

    Byerly, Alicia Michelle
    The vestibular system is housed within the bony labyrinth of the inner ear and is made up of three semicircular canals, which respond to angular head movements, and two otolithic organs, which respond to linear head movements. There are multiple diseases and disorders that can negatively impact the function of the vestibular system and result in symptoms including vertigo and imbalance. Audiologists perform many diagnostic evaluations to assist with the differential diagnosis of vestibular disorders, including videonystagmography (VNG), posturography, rotational chair, and vestibular evoked myogenic potentials (VEMP). These evaluations are essential in determining the site of lesion and treatment options...

  13. The Speech Critical Band (S-CB) in Cochlear Implant Users: Frequency Resolution Employed During the Reception of Everyday Speech

    Wigand, Jason
    It is widely recognized that cochlear implant (CI) users have limited spectral resolution and that this represents a primary limitation. In contrast to traditional measures, Healy and Bacon [(2006) 119, J. Acoust. Soc. Am.] established a procedure for directly measuring the spectral resolution employed during processing of running speech. This Speech-Critical Band (S-CB) reflects the listeners’ ability to extract spectral detail from an acoustic speech signal. The goal of the current study was to better determine the resolution that CI users are able to employ when processing speech. Ten CI users between the ages of 32 and 72 years using...

  14. The Effect of a Contract on Patient Compliance in an Auditory Training Program

    Tarney, Erin B.
    The purpose of the present study was to assess the effect of a signed contract on patient compliance rates with the Listening and Communication Enhancement (LACE) aural rehabilitation program. A secondary purpose of this study was to assess subjective and objective treatment outcomes of the LACE program related to patient compliance rates. Twenty older adults with bilateral sensorineural hearing loss and who are users of binaural hearing aids were randomly placed into either the no contract (i.e., control) group or the contract (i.e., experimental) group, with the experimental group signing a contract before beginning the LACE program, and the control...

  15. Parent Experience with a Dual Diagnosis of Autism Spectrum Disorder and Hearing Impairment

    Stefanski, Julie
    The aim of the present study was to evaluate the experiences of parents raising children with a dual diagnosis of hearing impairment and autism spectrum disorder (ASD). Subjects were recruited through outreach to a network of professionals in related fields, as well as the Autism Research Institute’s Network for Deaf/Hard of Hearing and Blind/Visually Impaired. Five qualifying parents consented to participation in the study and shared their experiences in a one-on-one interview. Results were analyzed using strategies from the thematic network analysis theory, a qualitative research model. Parents reflected on their experiences during the diagnostic processes, throughout interventions and therapy,...

  16. Binaural Auditory Processing Among Middle-­Aged Adults

    Miller, Traci A.
    Binaural listening, or listening with both ears, allows a listener to better localize and understand speech than with one ear alone. For some aging adults, however, this binaural advantage does not exist, or is reduced relative to normal for speech-in-noise tasks. In addition, some older adults tend to exhibit an exaggerated right ear-­advantage (REA), or better recognition of signals presented to the right ear than the left during dichotic listening tasks, compared to young adults (i.e., Noffsinger et al., 1996). There is limited research, however, exploring if these age-­related changes in binaural listening begin to be demonstrated in mid-­life. The...

  17. Utilizing Social Media to Connect Adolescents and Young Adults with Hearing Loss

    Middaugh, Jessica L.
    The aim of the present study was to develop a social media network designed for adolescents and young adults with hearing loss. Five adolescents and young adults with hearing loss were recruited through central Ohio audiologists. Participants responded to two electronic surveys and took part in a focus group with their peers. Results indicated elements, or suggestions, that should be incorporated when designing a social media network for this population. A supplemental study was also conducted with four young adults with normal hearing who participated in a focus group and responded to the same questions relating to the social media...

  18. Importance of Motivational Interviewing Therapeutic Techniques in Audiology Clinical Work

    Livorno, Kristyn A.
    Hearing loss affects individuals, not just in a physical manner but in an emotional one. The beginning of a sensory loss is a form of psychological trauma that may cause shock and confusion. These emotional and psychological changes may create a reduced quality of life and increased social isolation. Individuals who are learning about their particular hearing loss or using hearing aids for the first time are likely to go through various emotions, which may include embarrassment, frustration, anxiety, depression, or fatigue which may affect how they interact socially. It is important that audiologists understand the necessity of counseling for...

  19. Noise-Induced Changes in Electrocochleography in the Fischer 344/NHsd Rat

    Kobel, Megan Janette
    There is a growing body of evidence suggesting that cochlear de-afferentation can occur without accompanying outer hair cell (OHC) loss after noise exposure. Due to the high incidence of noise exposure in the United States, there is a need to develop assessments that can identify and monitor this de-afferentation in noise-exposed listeners. The current study was undertaken to investigate changes in the components of electrocochleography (EcochG) in the Fischer F344/NHsd rat in order to assess long-term cochlear deafferentation from hazardous noise. Changes in the action potential (AP) and cochlear microphonic (CM) input-output (I/O) functions were measured after noise exposure. The CM/AP ratio was examined to account for between-test...

  20. Survey on Knowledge and Attitudes of Hearing Loss and Assistive Listening Technology with Children

    Hayes, Danyelle Nicole
    The aim of this study was to determine the level of experience obtained by classroom teachers located in Columbus, Ohio in the area of the educating children with hearing loss. Other areas of interest in the survey included the additional education regarding hearing loss in children and the willingness to make accommodations for children with hearing loss. A 35-question survey was sent to approximately 2,000 teachers in central Ohio. Questions in the survey focused on the teachers’ experience with hearing loss, educating children with hearing loss and their willingness to work with students with hearing impairment. Subjects were contacted twice...
