Resumé

To understand better how hearing loss affects spatial listening abilities in complex multi-talker situations, we investigated auditory spatial attention in 8 older adults with normal audiometric thresholds below 4 kHz and 8 older adults with bilateral sloping sensorineural hearing losses ranging from moderate to severe in the higher frequencies. In a condition with real spatial separation, a target sentence from the Coordinate Response Measure (CRM) corpus was presented from one spatial location and competing sentences from two different locations, with pre-trial cues specifying the target’s identity and location. In a condition with simulated spatial separation, corresponding perceived spatial locations of the target and competitors were achieved through exploitation of the precedence effect. Seven different probability speci cations indicated the likelihood of the target being presented at the three locations (100-0-0, 80-0- 20, 60-0-40, 0-0-100, 20-0-80, 40-0-60, and 50-0-50, respectively for 0°, 45°, and 90° azimuth). As expected, hearing-impaired listeners performed worse than normal-hearing listeners across all listening conditions, but especially in conditions where the location of the target was less certain. For both groups, performance was superior when the target was presented from the more probable location than when it was presented from the less probable location. Implications for clinical practice and future research will be discussed.
