Are Central Auditory Processing Skills in Middle Aged Adults Different from Young Ones?

Area of Science:

• Audiology
• Speech Perception Research
• Gerontology

Background:

• Auditory processing abilities can decline with age.
• Understanding age-related differences in speech perception is crucial for audiological assessments.
• Standardized tests are needed to evaluate these differences effectively.

Purpose of the Study:

• To compare speech perception abilities between middle-aged and young adults using Persian audiological tests.
• To evaluate the performance on the Persian version of the University of Cincinnati Auditory Processing Inventory (P-UCAPI), Persian words recognition score (P-WRS), Persian words in noise (P-WIN), and Persian competing words (P-CW) tests.
• To identify potential age-related deficits in auditory processing, especially in challenging listening conditions.

Main Methods:

• A cohort of 100 adults was recruited from the Audiology Department of Rohani Hospital in Iran.
• Participants were divided into middle-aged and young adult groups.
• Statistical analyses including paired sample t-test, independent sample t-test, and One-way ANOVA were employed to compare test scores (P-UCAPI, P-WRS, P-WIN, P-CW).

Main Results:

• No significant difference was found in the total P-UCAPI scores between the two age groups.
• Middle-aged adults scored significantly lower on the P-WIN test compared to young adults, with a notable deficit in the left ear.
• These results indicate a specific difficulty for middle-aged individuals in understanding speech amidst background noise.

Conclusions:

• Middle-aged adults exhibit poorer speech perception in noisy environments compared to their younger counterparts.
• The P-WIN test effectively identified age-related challenges in auditory processing, particularly in the left ear.
• These findings underscore the importance of considering age in audiological evaluations for speech perception in noise.
