In this study, ReSound Binaural Directionality III is compared to two commercially available binaural beamformers to explore the possible advantages and disadvantages of these very different approaches to applying hearing aid directionality.
How Asymmetric Directional Hearing Aid Fittings Affect Speech Recognition
by Brent C. Kirkwood, PhD
Charlotte T. Jespersen, MA
The speech intelligibility benefits of directional microphones in hearing aids have been well documented. There is little disagreement that hearing aid directionality can be beneficial for hearing aid users in noisy situations in which a user’s goal is to understand speech. The author’s outline how, by automatically adapting, hearing aids can help maintain speech intelligibility as the acoustic environment changes.
