Dose-Dependent Pattern of Cochlear Synaptic Degeneration in C57BL/6J Mice Induced by Repeated Noise Exposure

Figure 3

Dose-response relations between repeated noise exposure intensities with ABR threshold shifts at 1 day (a) and 14 days (b) after NE. The error bar represents the SEM for 8-12 mice in each group. Red arrows represent thresholds at 32 kHz frequency greater than 90 dB after the noise exposure.
