Fig. 3.
ABR thresholds of WT (circles) and BKα–/– mice (triangles) (A–D) and number of ears with DPOAEs found (E). (A–C) ABR thresholds (dB SPLrms) to click stimuli, given for individual mice (open symbols) and as mean (filled symbols) ± standard deviation as a function of age (A, 4 weeks; B, 8 weeks; C, 12–17 weeks). (D) ABR thresholds as a function of stimulus frequency for WT (circles) and BKα–/– (triangles) mice of 8–17 weeks of age. (E) Number of ears with DPOAEs found. DPOAE function below 10 dB SPL could not be detected due to limitations of the method.
