Objective Differences Between Premium And Mid-Level Digital Hearing Aids, Chelsea C. Barry

Dissertations, 2014-2019

This ongoing study compared premium and mid-level hearing aids from major manufacturers on noise reduction and general electroacoustic characteristics. The findings of this study will contribute to the scarce independent literature evaluating currently available hearing aid technology. Measuring the overall gain reduction in response to a steady state noise can objectively test noise reduction. However, such a method does not specifically test a hearing aid’s ability to reduce speech in specific narrow frequency bands. Hanline & Rout (2008) developed a set of stimuli to evaluate multichannel noise reduction algorithms more precisely. We used these stimuli to test noise reduction abilities …

Development Of A Questionnaire To Assess Attitudes Toward Hearing Aids, Corinne O'Shaughnessy

Dissertations, 2014-2019

Many reasons have been postulated as to why persons with hearing loss are reluctant to engage in the hearing rehabilitation process. While not the only determinant, an individual's attitudes toward hearing loss and hearing aids have been shown to affect adoption of amplification adversely and eventual outcomes of hearing aid use. Several attempts have been made to develop test instruments for attitudes toward hearing loss, but nothing specific to attitudes toward hearing aids or hearing aid technology. The primary objective of this study was to develop a questionnaire to assess attitudes toward hearing aids using the ABC model of attitude …

Hearing Loss And Third Party Disability: A Systematic Review, Kathleen H. Wallace

Dissertations, Theses, and Capstone Projects

Objective: The purpose of this investigation is to conduct a systematic review of the quality of life (QoL), social, and emotional aspects of third party disability experienced by communication partners of persons with hearing loss (PHL), including a comparison of communication partners of users of hearing aids, users of cochlear implants, and unaided persons with hearing loss.

Methods: A comprehensive search utilizing various peer-reviewed databases accessible through the City University of New York (CUNY) Graduate Center Library was conducted to identify relevant studies evaluating quality of life, social, and emotional outcome measures of communication partners of persons with hearing loss …

The Effect Of Hearing Aid Use On Cognition In Older Adults With Adult Onset Hearing Loss: A Systematic Review, Jona Cano

Dissertations, Theses, and Capstone Projects

The goal of this paper was to systematically review literature in order to investigate whether the use of amplification in the form of hearing aids by older adults positively impacts cognitive status. If the results of this review uncover a positive association between hearing-aid use and cognition, then hearing aids can be recommended as an intervention method for the mitigation of cognitive decline. The eight studies included in this paper were reviewed based on the research design and the cognitive outcome measures employed. Additionally, the secondary measures of health utilized by study investigators were also evaluated. Of the eight studies …

Bone Conduction Transmission And Head‐Shadow Effects For Unilateral Hearing Losses Fit With Transcranial Cic Hearing Aids, Marc A. Fagelson, Colleen Noe, Jennifer Blevins, Owen Murnane

Owen D. Murnane

Bone conduction transmission and head‐shadow effects were determined with transcranial completely‐in‐the‐canal (TCCIC) CROS hearing aids. Five subjects with documented profound unilateral hearing loss and experience with traditional CROS/BICROS fittings (TCROS) were tested with a CIC hearing aid placed in their poorer ear. Peak SPL was measured at the tympanic membrane and ranged from 105–115 dB SPL at 2000 Hz. Pure‐tone crossover thresholds and functional gain tested at frequencies from 250–8000 Hz varied considerably more than the SPL measures. The pure‐tone results indicated that sensitivity in the better ear was moderately associated with functional gain across frequency. Speech recognition was then …
