Background and Objectives Patients with hearing loss and tinnitus experience difficultyin engaging in daily conversations. However, only few studies have examined how tinnitus af-fects individual speech discrimination to comprehend speech. This study aimed to analyze thecorrelation between tinnitus frequency and speech discrimination in patients with hearingloss and tinnitus. Subjects and Method A total of 275 ears with hearing impairment were retrospectively an-alyzed via audiometry and tinnitogram. The ears were divided into three groups depending onthe frequency of their tinnitus. Average pure tone audiometry (PTA), hearing threshold of tin-nitus frequency, speech discrimination test (SDT), degree of discrepancy between tinnitusfrequency and worst PTA frequency were collected and compared among the three groups. Results No significant difference was observed in PTA in the three patient groups. Hearingthreshold of tinnitus frequency was the highest at 78.27 dB in the high-frequency group andthe lowest at 45.14 dB in the low-frequency group. SDT was significantly lower (53.69%) inthe low-frequency group. The correlation between tinnitus loudness and SDT was the stron-gest in the low-frequency group. The degree of discrepancy between tinnitus frequency andworst PTA frequency was also significantly observed in the low-frequency group. Conclusion Patients who are severely affected by tinnitus are found to have significant dis-crepancy between tinnitus frequency and worst PTA frequency, indicating decreased SDT.
