Masking and Interaural Phase. II. 167 Cycles

Masking level differences obtained for 167 cps are presented. Some involved shifting the phase of the signal through various angles, and others, shifting the noise in interaural time. Where the experimental conditions are comparable to Hirsh's at 200 cps, the data agree very closely with his. The data obtained with various interaural time differences in the noise are shown to differ sharply from comparable data taken at 500 cps.
