Responses of single fibers in the cat's cochlear nerve were studied before, during and after exposure to intense auditory stimuli. Exposure stimuli were pure tones at the fiber's CT or at 12 octave above (+12 octave) or below (-12 octave) the CF. Exposure levels were 85 dB and 90 dB SPL. The various exposures were evaluated in terms of the reduction of responding to test stimuli at the fiber's CF. At the 90-dB level the exposures at -12 octave produced greater response decrements and more prolonged recovery times than exposures at the CF. Effects of the 85-dB exposures at the CF and -12 octave were less severe, and were about equal to each other. Only a slight effect on fiber responses was found for exposure stimuli at +12 octave, whether at 85 or 90 dB. None of these exposures produced changes in CM. The relevance of these data to 'temporary threshold shift' and to basilar membrane mechanics is discussed.
