목적: To investigate the factors related to the decrease of speech discrimination ability in patients with presbycusis and, to find out whether aging has a significant effect on speech discrimination decrement. 방법:We retrospectively analyzed the medical records of 103 patients over 40 years of age and who underwent pure tone audiometry (PTA), speech audiometry (SA), and auditory brainstem response (ABR) for hearing loss at our hospital from January 2019 to June 2021. 결과:We enrolled 120 ears of 103 patients with mean age of 65.8±11.9 years. The mean pure tone audiometry (PTA) threshold (0.5, 1, 2, and 4 kHz) was 37.2±27.7 dBHL, and the mean speech discrimination score was 82.5±22.3%. In the correlation analysis, there was a significant negative correlation between the patient's speech discrimination score and age, and all variables of PTA, and auditory brainstem response (ABR) also showed significant correlation with the patient's speech discrimination score. Among them, the mean PTA threshold average showed the strongest negative correlation with it. When the significant predictors of speech discrimination score were analyzed through multiple linear regression test, the PTA threshold average and age showed significant results 결론:The speech discrimination ability of elderly patients with hearing loss significantly decreased with the increase of the mean PTA threshold and the increase of age, and among the two, the decrease in hearing sensitivity is the more important factor.
