Résumé

The effect of within-and between-talker variability on word identification in noise by younger and older adults was demonstrated. The participants included 16 younger and 16 older adults that spoke English and had pure-tone audiometric thresholds of &le25 dB HL at frequencies from .25 to 3 kHz in the test ear. The stimuli used were the eight sentence lists of the SPIN-R test and each list contained 25 low-context and 20 high context-sentences. Each participant was tested on the eight lists with list order counterbalanced and sentences were presented monaurally under TDH-50P earphones at 50 dB SL. Each sentence was presented with corresponding files of multi-talker babble at 0 dB S:N and each participant was instructed to report the last word of every sentence. The results show that the younger adults correctly identified more words in noise than older adults and the word identification was best for talking conditions with louder noise environments.
