Subjective Differences Between Premium And Mid-Level Digital Hearing Aids, Dakota Sharp

Dissertations, 2014-2019

This study compared perceptual differences between premium and mid-level hearing aids from a major manufacturer in normal hearing listeners. Limited literature currently exists comparing perceptual differences between premium and mid-level digital hearing aids. This information is highly important in decision-making for clinicians and patients alike. Barry et al. (2018) evaluated four major hearing aid models’ noise reduction properties and determined that one manufacturer’s premium and mid-level devices demonstrated significant differences in noise reduction gain in frequencies associated with human speech. We programmed this device for a mild sloping to moderately-severe SNHL using the manufacturer’s proprietary fitting formula and noise reduction …

Audiologists’ Preferences In Programming Cochlear Implants, Leanne Browning

Dissertations, 2014-2019

Cochlear implants have become a viable option for those with severe to profound sensorineural hearing loss who gain little benefit from hearing aids and have poor word recognition ability. However, the techniques audiologists use to program these devices are not standardized (Sorkin, 2013). There is little data available which analyzes how audiologists handle clinical cochlear implant programming between the top manufacturers. These companies supply default settings in their products but is it unknown how often audiologists use these in practice in the United States.

In the present study, a questionnaire based on previous European data from Vaerenberg et al. (2014) …

Do Different Methods Of Hearing Aid Information Delivery Influence Knowledge Acquisition?, Lindsey Ann Parr

Dissertations, 2014-2019

The main purposes of this study were to examine whether or not there was a difference in knowledge acquisition as a function of training method (these included: face-to-face session, DVD, and pamphlet); to determine which information included in hearing aid orientation was commonly known prior to training and which showed the most learning after training; and to evaluate which training method is the most popular among participants. A sample of 65 young college students with no prior hearing aid experience completed a pre- and post-multiple-choice test of hearing aid knowledge and gave their opinion of the hearing aid orientation immediately …

Comparison Of Speech Intelligibility Over The Telephone Using A Hearing Aid Micorphone And Telecoil, Phillip K. Bond

Dissertations, 2014-2019

The purpose of the current study is to determine if the smaller, modern hearing aid has affected the speech intelligibility over the telephone using a telecoil and hearing aid microphone. Six hearing impaired listeners were situated in a quiet office and were asked to repeat aloud Connected Speech Sentences (CST) they heard through the telephone while wearing their hearing aid in telecoil only mode, microphone only mode, and without their hearing aid. The CST sentences were presented in three different signal-to-noise ratios (Quiet, +10dB, & +5dB) with the recorded speech babble of the CST test. It was discovered that the …
