Table 3.
The mean threshold in the baseline (no-modulation) condition (expressed in signal-to-masker ratio in dB) and masking release (dB) reported for each listener group and masking condition. Masking release is computed relative to the SRT in the baseline no-modulation condition. Standard deviations are shown in parentheses below each mean.
