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 …
