Binaural interaction in cat and man. I. Signal detection and noise cross correlation
Susan A. Hoppe, Ted L. Langford · The Journal of the Acoustical Society of America · 1974
Detection of diotic 500-Hz tones partially masked by diotic and dichotic noise was studied in the cat and compared with similar detection data for man. The interaural correlation of the masker was varied by delaying the channel to one ear from 0 to 5 msec in steps of 1 msec. An avoidance response was used to measure detectability. The absolute sensitivity of the cat was less than that of man and smaller MLDs were found for the cat at each delay. The temporal interval over which the binaural system of the cat is able to effect a correlation between events occurring at the two ears was estimated to be smaller, while the critical band appears to be wider than in man.
