Rats in groups 2, 3, and 4 were exposed to 120 dB noise in the 4 kHz octave band for 4 hours. The auditory brainstem response (ABR) test was performed in all groups on day 1 after noise exposure and was repeated in groups 1, 2, and 3 on day 5. Auditory brainstem response thresholds were recorded at 8, 12, 16, 20, and 32 kHz frequencies.
