TABLE II.

Linear mixed-effects model (LMM) summary describing the effects of the SNR and masker-present gain reduction estimate on speech recognition (RAU). The interaction between the SNR and masker-present gain reduction estimate was a nonsignificant factor and was removed from the model during model testing. Significant fixed effects are shown in bold with a Satterthwaite approximation used to generate p-values.
