Figure 1

Pure tone audiometry (PTA) test of the long-term bilateral moderately severe sensorineural hearing loss (SNHL) patients and healthy controls (HCs). (a) Mean (±SEM) PTA of right ears of the SNHL group and HCs. Compared to HCs, thresholds are significantly higher in right ears of the SNHL group at 0.25, 0.5, 1, 2, 4, and 8 kHz, p < 0.001. (b) Mean (±SEM) PTA of left ears of the SNHL group and HCs. Compared to HCs, thresholds are significantly higher at every frequency, p < 0.001. (c) There was no significant difference between left and right ears in long-term bilateral SNHL subjects, p > 0.05.
