Table 1.

Mean speech recognition thresholds (SRTs, dB SNR) with and without simulated UHL for children and adults in each masker. The target and masker were either co-located (co-loc), or the masker was presented from the side (msk-side); in the simulated UHL condition, the masker was presented either ipsilateral (msk-ipsi) or contralateral (msk-contra) to the simulated loss. Standard deviations appear below each mean, in parentheses.

^*Indicates mean difference between children and adults is significant (p < .05) with Bonferroni adjustment for multiple comparisons.
