Figure 5: Recovery from noise injury. DP-grams (L1/L2 = 55/35) obtained at 1 day, 1 week and 4 weeks post noise exposure are illustrated for the control, noise and CAE+noise groups. Both the noise-only group and the CAE+noise group were exposed in the same noise exposure chamber at the same time. Note that the CAE treated group showed faster recovery than the noise exposure group. The continuous gray lines in each panel represent baseline recordings and the broken gray lines are the noise floor. Errors bars are standard errors of the means.
