Abstract [en]

The addition of visual cues to amplified auditory signals by hearing aids resulted in better identification of speech stimuli relative to unaided audiovisual or aided auditory-only conditions (Walden et al., 2001). An important question that remains unexplored is whether hearing-aid users have the same level of ability for audiovisual speech perception relative to their age-matched normal hearing counterparts.

Here we present the preliminary findings from collected data of 18 elderly hearing-aid users and 18 normal-hearing listeners in gated-audiovisual identification of different types of speech stimuli (consonants, words, and final words in low-predictable and high-predictable sentences). In terms of isolation point (IP; the shortest time from the onset of an speech stimulus required for correct identification of that speech stimulus), results showed that elderly hearing-aid users needed more IPs for identification of consonants and words than elderly normal-hearing individuals under quiet condition. There were no differences between two groups in IPs needed for identification of final words embedded in low-predictable or high-predictable sentences. In terms of accuracy, both elderly hearing-aid and elderly normal-hearing groups achieved ceiling on audiovisual identification of speech stimuli under quiet condition.
