Morphological and functional preservation of the outer hair cells from noise trauma by sound conditioning
B Canlon, A Fransson - Hearing research, 1995 - Elsevier
Guinea pigs were sound conditioned to a low-level, long-term pure tone stimulus (1 kHz, 81
dB SPL, 24 days) before exposure to a traumatic noise (1 kHz, 105 dB SPL, 72 h). Auditory
brainstem response thresholds and distortion product otoacoustic emissions were obtained
at selected frequencies before sound conditioning and at day 1, 5, 10, and 15 during sound
conditioning as well as on the final 24th day. Auditory brainstem responses at 1 and 2 kHz
were not affected at any time during sound conditioning. The amplitude of the distortion …
