Figure 2

The left column specifies the two babble thresholds collected, and under what conditions they were used to adjust the signal level; the middle column specifies the conditions under which R-SPIN thresholds were obtained; and the right column illustrates the four dialog comprehension test conditions in the experiment. The top row (A) specifies the babble, R-SPIN and dialog comprehension scenarios for the real no-separation condition. The three other conditions share the same babble threshold but differ from each other in respect to the R-SPIN and the dialog comprehension tasks. The second row from the top (B) illustrates the R-SPIN and dialog comprehension for the real spatial separation condition, the third row (C) illustrates the settings for the virtual no-separation and the fourth (D) specifies the settings for the virtual spatial separation. Orange stands for R-SPIN, red stands for talker 1, blue for talker 2, and gray for babble.
