BACKGROUND AND OBJECTIVES: The aim of this study was to investigate the factors associated with decrease in speech discrimination ability seen in patients with presbycusis and whether aging has a significant effect on the observed decline.
SUBJECTS AND METHODS: We retrospectively analyzed the medical records of patients aged >40 years who had undergone pure-tone audiometry, speech audiometry, and auditory brainstem response for hearing loss at our hospital from January 2019 to June 2021, and investigated the factors that correlated with speech discrimination score.
RESULTS: We enrolled 103 patients with 120 ears, with a mean age of 65.8±11.9 years. The pure-tone average of the patients' thresholds at 0.5, 1, 2, and 4 kHz was 37.2±27.7 dB HL, and their mean speech discrimination score was 82.5%± 22.3%. A correlation analysis revealed a significant negative correlation between the patients' speech discrimination scores and age. In addition, all variables of pure-tone audiometry and the patients' auditory brainstem responses were significantly correlated with the speech discrimination scores. The pure-tone average had the strongest negative correlation. On analyzing the significant predictors of lower speech discrimination scores, using a multiple linear regression analysis, pure-tone average and age showed significant results.
CONCLUSIONS: The speech discrimination ability of older patients with hearing loss significantly decreases with increasing pure-tone average and age.
