Fixed effects of gain and noise filtering indices on DNN performance improvement. (A) Distribution of gain change and noise filtering indices over electrodes within each background noise class. (B) Fixed effect is shown with confidence intervals from a linear mixed effects model (with subject label as the random effect) predicting an electrode’s DNN correlation improvement over a STRF from gain change and noise filtering indices for each type of noise transition, along with the Pearson correlation to measure the model’s prediction strength in a given noise condition. Red and blue indicate positive and negative effects, respectively. Gray effects were not statistically significant.
