Abstract

Objective: Speech perception difficulties in aged people are usually shown in adverse auditory conditions like a high background noise that decreases SPEECH TEMPORAL RESOLUTION. In our study, SPEECH TEMPORAL RESOLUTION was compared between young and elderly adults via measurement of word discrimination score in both continuous and INTERRUPTED NOISEs.Method: Monosyllabic word discrimination score in three signal to noise ratios of 10, 0 and -10 dB with continuous and INTERRUPTED NOISEs was measured to determine effect of stimulus redundancy and SPEECH TEMPORAL RESOLUTION among 30 young adults with the age range of 18 to 30 years old, and 32 elderly people with the age range of 60 to 80 years old with normal hearing of both genders.Results: A significant difference was shown between the word discrimination scores with the three signals to noise ratios of both continuous and INTERRUPTED NOISEs in each group, and in both groups, too (p<0.011). Word discrimination score was lower in continuous than INTERRUPTED NOISEs in both groups (p<0.001). Temporal resolution was lower in aged people than in young adults in the three signals to noise ratios and significant in -10 dB level (p<0.001). Sex had no effect on the results.Conclusion: Lower function of elderly people with normal hearing in speech recognition in the presence of temporal-modulated than CONTINUOUS NOISEs can be defined as their weak performance to use speech redundancy and free of noise. Our result reconfirms the effect of age on speech perception difficulties of elderly people than loss of hearing thresholds.
