Audiological evaluation of Stat3ΔOHC and Stat3ΔSC. (A) The number of OHCs was not altered, however (B) DPOAE levels were significantly reduced at 12 (p < 0.01), 16, 20 and 24 kHz (p < 0.001) of Stat3ΔOHC (n = 6) but not of Stat3ΔSC (n = 6). (C) Click ABR showed an increased hearing level of Stat3ΔOHC and Stat3ΔSC up to 20 dB SPL compared to control animals (p < 0.001). (D) In addition, tone ABR performance revealed a significantly reduced hearing level at 12, 20 and 24 kHz (p < 0.05) of Stat3ΔOHC and at 8 (p < 0.05), 12, 16, 20 and 24 kHz (p < 0.001) of Stat3ΔSC. Ctrl, Stat3ΔOHC, Stat3ΔSC: n = 6. DPOAE and Tone ABR: Ordinary two-way ANOVA with Dunnett’s multiple comparison test. Click ABR: One-way ANOVA with Dunnett’s multiple comparison test. Significances: *p < 0.05, **p < 0.01, ***p < 0.001.
