ABR Thresholds of auditory brainstem response before and after noise exposure (NE). Statistical data representative of ABR (auditory brainstem response) thresholds before and one day after noise exposure (n = 13 from 13 animals) in guinea pigs. Four frequencies were tested: 2 kHz, 4 kHz, 8 kHz, and 16 kHz. *Significant difference from pre-NE group at the same frequency (P < 0.01).
