Figure 2. Hearing loss at 2h after noise exposure.
DPOAEs recorded before and after noise exposure at f2 frequencies 4, 8 & 12 kHz for ten animals subjected to proteomic screening indicate that exposure to 0.5 – 8 kHz noise at 112 dB SPL for 2 h induced a significant decrease in the DPOAE amplitudes at 2h after noise exposure. The results are expressed as mean ± standard error, n = 10. The traces pre- and post- NF are the noise floor levels of the DPOAE recordings done before and after noise exposure.
