Figure 7.

Effect of implantation and noise on ABR click thresholds over time. The mean (line) and individual (points) click hearing thresholds of left (implanted) (dark grey) and right (not implanted) (light grey) ears are illustrated over time. Since overlaps occur, the number of points does not correspond to the number of animals. There is a significant difference between the two groups on day 0 before noise trauma, i.e., 7 days after HDD implantation with left (implanted) ears showing a higher threshold. All other time points show no significant difference in the click hearing thresholds between groups. * p ≤ 0.05.
