Noise induced ABR threshold shifts 2 hours after the noise exposure. (A) The narrow band noise (120 dB SPL with 1000 Hz bandwidth for 1 h) induced about 30 dB SPL threshold shift at 12 kHz on the exposed ear, and about 20 dB shift at 12 kHz and no threshold shift at 4 to 6 kHz. (B) There were less than 10 dB threshold shifts on non-exposed ears. (* p<0.05)
