Comparison of hair cell numbers in left and right ears of animals matched ABR criteria for noise-induced damage. Remaining numbers of outer (OHC) and inner hair cells (IHC) were nearly symmetrical in both ears (n = 4). There were no significant differences in numbers of OHC or IHC between left (L) and right (R) ears with paired t-test.
