Responses of primary auditory fibers to combined noise and tonal stimuli.

Responses to tonal stimuli, with and without added noise of different bandwidths, were obtained from anesthetized cat auditory-nerve fibers using glass micropipettes. When low-pass noise with a cut-off frequency at least one octave below best (or characteristic) frequency was used, every fiber tested at high enough intensities showed a suppression of the… (More)
