Noise-Induced Tinnitus Using Individualized Gap Detection Analysis and Its Relationship with Hyperacusis, Anxiety, and Spatial Cognition
Figure 4
Auditory brainstem responses from the exposed left ear (A) and unexposed right ear (B).
In the exposed ear (A), both the tinnitus(+) and tinnitus(−) groups showed significant threshold shifts across tone-burst frequencies at 1 and 8 weeks post-exposure, with the strongest elevations occurring at 12 and 16 kHz. Overall, the tinnitus(+) group had significantly higher hearing thresholds than the tinnitus(−) group, although the thresholds were not significantly higher at any individual frequency or click. (B) No significant threshold shifts were seen in the unexposed ear for tinnitus(+) and tinnitus(−) groups. The control group showed no changes in either ear (A–B). Error bars represent SEM.
