FIG. 2. — Thresholds for detection of the stimulus in various free-field masker conditions (Experiment 1) as a function of signal source location in the horizontal plane. Each panel shows median data from one listener, labeled as Lxx at the top of the panel. Filled and open symbols represent thresholds for masker levels of 72 and 42 dB SPL, respectively, and +'s represent unmasked thresholds. Diamonds and circles represent UN and CM conditions, respectively. Horizontal dotted lines show masker levels at 42 and 72 dB SPL.
