• Aim– Examine (1) age-related changes in ability to identify
consonants in consonant-vowel-consonant syllables in noise and (2) sentence reception thresholds (SeRTs).
• Relevance– Speech understanding in noise declines with age,
even with normal hearing. • Could reflect reductions in phonological processing ability
or impairments in semantic and lexical processing required for sentence understanding.

Method
• Tested 16 older subjects with normal hearing (ONH) and 16 younger subjects with normal hearing (YNH).– Experiment 1:
• California Syllable Test (CaST).
– Experiment 2:• Quick Speech in Noise Test.• Hearing in Noise Test.

Results• Experiment 1
– ONH subjects performed worse than YNH subjects, particularly for hard-to-identify consonants.
– Otherwise showed similar influences of consonant position, lexicality, and vowel nuclei.
– CaST performance was independently affected by age and audiometric thresholds.
• Experiment 2 – No significant age-related
changes in SeRTs. – SeRT preservation in ONH
subjects reflected age-resistant ability to identify easy consonants in noise and intact top-down contextual and lexical processing.

Age-related increases in consonant identification thresholds varied for different consonants.

Conclusion
• These results establish benchmark values that can be used to evaluate success of audiological rehabilitation in older subjects with hearing impairment.
