A clinical audiologist performed pure tone audiometry (PTA) using a GSI-61 audiometer in the ENT department of Zhongda Hospital. Air conduction thresholds in the left and right ear were assessed at 0.25, 0.5, 1, 2, 4, and 8 kHz using standard clinical procedures (Figure 1). Impedance testing was conducted to rule out middle ear dysfunction test and conductive hearing loss.

Hearing thresholds at 0.25, 0.5, 1, 2, 4, and 8 kHz. (B) Mean right-ear audiogram of SNHL group and Control group. (A) Mean left-ear audiogram of SNHL group and Control group.
