Fig. 9. Reduction of DPOAE in Cx26+/− mice after noise exposure.
Mice were 6 months old and 3 months after noise exposure. Cx26+/− mice without noise exposure served as control. (A) Reduction in DPOAE in Cx26+/− mice after noise exposure in the I/O plot. In comparison with control Cx26+/− mice without noise exposure, DPOAE in noise-exposed Cx26+/− mice was significantly reduced. (B) The reduction of DPOAE in the noise-exposed Cx26+/− mice in the frequency range. I1/I2 = 60/55 dB SPL. DPOAE in the noise-exposed Cx26+/− mice appears to have significant reduction in comparison with control Cx26+/− mice without noise exposure. *P < 0.05 and **P < 0.01, two-tailed t test.
