Auditory and Cognitive Effects of Aging on Perception of Environmental Sounds in Natural Auditory Scenes.
Purpose: Previously, Gygi and Shafiro (2011) found that when environmental sounds are semantically incongruent with the background scene (e.g., horse galloping in a restaurant), they can be identified more accurately by young normal-hearing listeners (YNH) than sounds congruent with the scene (e.g.,...

This study investigated how age and high-frequency audibility affect this Incongruency Advantage (IA) effect. Method: In Experiments 1a and 1b, elderly listeners (N = 18 for 1a; N = 10 for 1b) with age-appropriate hearing (EAH) were tested on target sounds and auditory scenes in 5 sound-to scene ratios (So/Sc) between -3 and -18 dB. Experiment 2 tested 11 YNH on the same sound-scene pairings lowpass-filtered at 4 kHz (YNH-4k). Results: The EAH and YNH-4k groups exhibited an almost identical pattern of significant IA effects, but both were at approximately 3.9 dB higher So/Sc than the previously tested YNH listeners. However, the psychometric functions revealed a shallower slope for EAH listeners compared with YNH listeners for the congruent stimuli only, suggesting a greater difficulty for the EAH listeners in attending to sounds expected to occur in a scene. Conclusions: These findings indicate that semantic relationships between environmental sounds in soundscapes are mediated by both audibility and cognitive factors and suggest a method for dissociating these factors. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: N holdings: @attributes: islocal: N |
