By using these filtered materials, a single binaural and two monaural articulation functions were derived for each of 36 normal subjects. In the binaural condition 12 subjects received only low-pass filtered materials, while 12 others received only the high-pass signal. The remaining 12 received both signals simultaneously, one to each ear, in their binaural condition. Monaural functions for the two types of signal rose with approximately equal slopes. The slopes of the binaural functions obtained for a single signal failed to differ from those of the monaural counterpart. Conversely, the slope of the binaural function for the combined signal markedly exceeded those of the monaural ones. The technic described appears promising as a means of identifying patients with central auditory lesions. Author
