Differences in signal-to-noise ratio (SNR) loss on the QuickSIN test between sessions with and without personal sound amplification products.
Each line represents an individual’s data.

Results for the word discrimination task (predicted values).
(A) The bar graph displays the main effect of signal-to-noise ratio (SNR) for accuracy. (B) The bar graph displays the main effect of session for accuracy. (C) The bar graph displays the main effect of SNR on reaction time. Each dot represents one participant. Error bars represent 95% confidence intervals of the mean.
