TABLE 6.

Columns 2–4 show masked thresholds (dB re 1 μA) for on-site probes, for the four subjects of experiment 3 who were tested with the TP_SYM masker. The first column shows the subject and masker electrode tested. Columns 5–7 show the results of unpaired t tests between the two conditions shown at the top of each column. These t tests were performed using the four runs tested with each masker and are not corrected for multiple comparisons. Significant differences at the 5 and 1 % levels are shown by single and double asterisks, respectively
